Dead start, no beeping and black screen.

Question

Hello,

I just signed up and I have a problem,

the computer won't start anymore, the only thing that lights up is the LED and the fan starts running, but that's it, no BIOS loading and no startup... I don't understand, and I know nothing about electronics...

I cleaned it out (haha), I took apart and reassembled the graphics card, the same for the RAM. Nothing... just a neutral whirring from the fan when I turn it on and no reaction from the drives or the hard disk...

My hardware:
Pentium 4
Motherboard Cosmos?
50 GB hard drive
Nvidia GeForce2 440MX I think
It's the stupid marketing from Packard Bell Imedia version Images and Sound...

There you go...
I mainly have questions about repairs in stores, how much does it cost, what are the tricks to avoid being scammed... etc... but I'll come back for now if you have any ideas to avoid going that route, I thank you....

Hello everyone,
I'm posting here for information as I just fixed a PC today that had a black screen and was impossible to restart.
I'll skip the numerous hardware tests that were done before this PC could reboot.

*For your information, here are the symptoms that this PC had =>
it shut down abruptly while browsing the internet, couldn't restart, total black screen, the fans were running, the "Asus" logo was lit, all peripherals were fine, so the problem was either a dead motherboard (very likely) because NO BEEP during the various startups or a dead CPU (possible but very unlikely).

*So here are the two things I did =>

1.) The only thing I hadn't done yet was swap the 2 memory sticks (2* 1GB) from the yellow slots to the black ones, so I did that.

2.) I removed the power cord from the power supply, the motherboard battery, and switched the "CLRTC" jumper to position 2 and 3 to perform a ClearCmos and waited a good minute (at least we're sure).

3.) I left the memory sticks in the black slots, moved the "CLRTC" jumper from position 2-3 back to 1-2 (normal position), replaced it with a new battery (I had forgotten my tester at home), and reconnected the power cord.
Fortunately, the PC restarted (don't forget to take a quick tour in the BIOS to reconfigure the boot settings, language, date, and time...)

I hope this can help you a bit, and take advantage of having the PC open to thoroughly and gently clean the various fans and, for the best, change the thermal paste.
Good luck.

In my opinion, the store is only going to repair it at best if it's guaranteed and broken for good at worst, it's a new equipment purchase in perspective.
As for the problem, you should find a kind soul to check the essential components, like a good friend who enjoys tinkering with their PC. Could you please specify if there is a beep on startup, a display, the keyboard LED, ...?

Hi! If you have an internal modem, try removing it; sometimes that's all it takes. Try with the other PCI cards (white connector in your PC). If you're getting a repair done at a shop, first ask them if they charge for diagnostics, then ask for a quote after the diagnostics.

Thank you,  the problem now is that I have unplugged everything and left only the motherboard, the graphics card, and the RAM. A green light comes on, the fan spins, but the screen tells me there is no signal and to check the video cable... which I have done... nothing...  I tested a clear CMOS, I removed the battery... nothing I’m looking...

RevesNoirs · Answer

When I turn on my computer, a green light comes on at the base. I hear the fan running, but there is the message "No Signal."

PS: A lot of explanation... I’m repeating myself, but maybe this last explanation will be clearer.

Thank you for all your help.

revesnoirs · Answer

Is it possible to recover the hardware or do I have to buy a new PC?

RevesNoirs · Answer

The question is mainly:  in the event that my motherboard is dead.. what would be the best financial way to rebuild the PC?? is it possible to recover the processor?

jc49 · Answer

first, you need to make sure that your motherboard is dead (it could also be the graphics card...) After that, it depends on which Pentium 4 you have, how much RAM you have, etc... Provide more details.

Coolpit · Answer

I have the same problem as Shakatak
I did the same thing, removed the fan, removed the CPU
put the CPU and fan back in and poof, nothing when starting up... :(
black screen
the CPU fan spins
the hard drive spins, basically everything seems to be powered, but... black screen
the red LED on the front stays on as well as the charging light (green) and... nothing... I remain in complete darkness, the most frustrating...
I need help urgently...
I've been on the forum for hours looking for similar problems and solutions but so far... black screen... :)

Thanks in advance
config: Athlon 1400, 400 DDR, ASUS A7M266, GeForce 2GTS
PS: I haven't made any changes in the BIOS or on my PC, I just removed and reinserted the CPU, that's all...

Hi, I had the same situation as you.
Unplug everything and try with the bare minimum.
If it still doesn't work, remove the battery for 5 hours
and if there's still no success, have someone test your processor (that was my issue). I thought it was the motherboard.

cyje · Answer

Same for me, but I have one more piece of information. My PC works with a flat screen, but not with any CRT screen... There is something different in the way the display is handled between TFT and CRT. But I'm lost, I don't understand why? If someone knows, they will be my savior...  I would just recommend before changing everything (motherboard and processor), to try with a flat screen...  I found information elsewhere suggesting to unplug everything except the VGA cable, and to restart the machine like that, to possibly fix an EPROM offset.  Best wishes (bright) to everyone.  cyje

Hello,

here's the situation: I have a PC at home (my sister's) that shows "no signal or cable disconnected" on the screen for a few seconds when we try to start it and then goes into sleep mode.
I've tried

clearing the CMOS = still nothing
removing and replacing the BIOS battery = nothing
moving the jumper and then putting it back in its original position = nothing

when a graphics card is dead, does the fan keep spinning? I don't think so.

I suspect it's between the GPU and the motherboard, but I don’t think the motherboard is dead since at startup the keyboard lights blink once and then nothing.

Do you think it's the GPU??

pioopioo · Answer

Here is the translation of your text:

Here, I just read all this, but my problem is this: I removed my processor to see if it would work in another one of my PCs, and unfortunately, it didn't fit, so I put it back in. Then I wanted to turn my PC back on, and everything powers up—fans, mouse, keyboard, everything—except the screen; there's not even a beep. The screen is as if the PC were off. Yet, I didn't touch anything else in the PC; I just removed the processor and put it back in, and since then, my computer doesn't work anymore. Please help me.

Hello,
For about 3 months, I’ve also had this issue of 3 beeps leaving a black screen!
I turn off the power for 30 minutes and restart it! If it doesn’t start, I have to insist, and sooner or later it eventually restarts! Yes, I know it’s annoying and likely indicates that my 5-year-old motherboard is nearing the end of its life... The tested memory sticks, 2X 512 MB, are fine. But I repeat, you have to insist before changing your motherboard if you don’t have the budget yet!

Hello,

I also have a similar problem with my girlfriend's PC:

- I gave her my hardware (motherboard, graphics card, CPU, RAM) to integrate into her case. Everything was working fine, but we got a message saying that the graphics card was not getting enough power and that it would go into economical mode (or something like that). We managed to run it like this for a while with a low resolution.
By the way, I should mention that the graphics card is a 6600GT (Leadtek).

- Then we changed her power supply to a more powerful one, and that's when nothing worked anymore: no beeping, black screen, and keyboard LEDs turned off. (What still works: motherboard LED, case and CPU fan, mouse LED.)

Of course, I checked the power supply, and it's working.
I thought we had damaged the graphics card or the AGP port on the motherboard. Indeed, the graphics card fan hasn't turned since then.
Unfortunately, I can't test the graphics card with mine because I've switched to PCI. In fact, I can't test anything at all with mine.

So for Christmas, I bought her a new graphics card (which doesn't require direct power connection this time), but it hasn't changed anything.

How can I tell if it's the CPU or the motherboard?

Alexielle · Answer

Similar problem with my friend's PC.
I press the button to turn it on.
1- The fan is running loudly (the last 2-3 times it was turned on, it did the same but everything else
worked normally).
2- No startup beep.
3- The screen remains black.
4- Unable to open the DVD drive (except a DVD is stuck inside...)
Any idea to help us?
Thanks.

Hello
I have two DDR 256 RAM sticks, one for each. My problem is quite weird (lol)
if both RAM sticks are in place, only one RAM works even though both are fine.
Well, if you have any suggestions, thank you.

Good evening
I have a problem similar to yours
Indeed, I got a WWII computer from a friend that works perfectly on a CRT monitor but does not work at all on a TFT or even a plasma screen; it has no graphics card, just an integrated chipset. If someone can help me, I would be very grateful
No BIOS display, nothing with a flat screen, I'm stuck...
Best regards
Thank you for your insight

same problem, on two machines, ! ! !
-1st pc
-p4d 3.2
-8600gt pcie gigabyte
-msi motherboard
-2x 512 @533mhz ddr2 corsair
-500w noname power supply
-intel heatsink
-----------------------------------------
2nd pc
-p4d 3.4
-9600gt Asus Silent version powered
-Asus p5nsli motherboard
-3x1ghz @667mhz ddr2 corsair
-750w Advance power supply
-asus processor fan

same issue on both machines black screen at startup and no beeps
I tested all the components on the 2nd pc, and nothing is defective !! ! ! !! !
incomprehensible
on pc 1 I managed to find the fault
-intel heatsink poorly positioned and overheating, I moved it a bit, and boom perfect startup....

-for pcs with a powered graphics card, the problem often comes from the power supply which burns out .... do not buy Advance or noname, you really need to spend money on a reputable power supply !!!!
-this problem often also comes from the processor (pentium d) overheating a lot at startup, and if it is dirty or poorly positioned the motherboard will refuse to start ..
personally I still have an issue on pc n1, I changed the motherboard, the processor, the graphics card, even tested another power supply..........so it's a mess, I advise people with the same problems as me to test their parts on another pc (and yes it's better to always have a test machine at home it helps ..) otherwise ask a friend

-this fault results in either:
-dead motherboard !!
-dead processor !!
-dead graphics card !!
-dead power supply !!
-or memory dead or incompatible !!

Have others also found solutions to their problems? Because I'm having the same issue after cleaning the processor's fan, and everything was working normally just before, so I don't think a part is dead...

artaxerxes06 · Answer

Hello everyone,
I'm having a startup problem with my PC (Packard Bell, AMD 4200+ processor, GeForce 7500 LE graphics card, Windows XP that came with the PC). When it was turned off: Upon powering on, the fan is running, the hard drive light turns on, but nothing happens, meaning Windows doesn't start and the monitor indicates that there is no signal detected. However, when I unplug the power and the monitor, hold the power button for a long time, and plug everything back in, after several attempts, the computer starts working again, which means Windows boots up normally. Additionally, when I put the computer to sleep, I can restart it normally by pressing the space bar. Could it be the motherboard battery, as mentioned in the forum, or something else, like a problem with the hard drive or graphics card, or...?
Could someone help me? Thank you in advance.

Hi, I'm new and I'm asking for help with my problem. I changed the case of my PC and when I try to turn it on, nothing happens, no lights, no beeps, no fans, nothing. So I unplugged everything and put it back in my old case, and the same problem occurred. I wondered if it was the power supply, so I changed it but still nothing. Then I removed all the PCI ports and still nothing. Please help me!!!!!
My configuration is: Acer Aspire T660-K97Z, Intel Pentium 4, ATI Radeon Xpress 200 series, 512MB DDR2, Windows XP

Good for desktop PCs, remove your motherboard with the processor and the graphics card, HDD, etc., and place it in another case. If the same problem persists, let me know. Cheers!

Choucroute · Answer

Hello, I have a similar problem: no beeping and a black screen on startup, but everything seems to be working since all the fans are turning on (power supply, graphics card, and processor), I can open the DVD drive and the hard drive seems to be active. In your opinion, where could the problem be coming from? Subsidiary question: when the fan is running, does it mean that the hardware is functioning? Particularly for the graphics card and the power supply?  My hardware: - Asus M2R32 - 4200+ AMD Athlon 64x2 - Ati Sapphire X1950 Pro - 650W Advance - 2x 1024 @800Mhz DDR2 Corsair

dédé62 · Answer

Ah, I have the same one. Everything seems fine but the screen stays black and it doesn't beep. However, when I remove the battery and put it back in, the PC starts up. But it freezes shortly after. I think the motherboard is having issues or the CPU is at the end of its life.

this little post to unveil my magic tool: I have an internet café in Thailand for a few years now and I often face this kind of "dead startup" problem (the weather conditions here are bad for computers: heat and humidity) and so I discovered this trick from Thai PC builders
the little thing that can save your computer is.......TADAAAAAAMMMM.........:
the eraser!!!!
use it to "erase" the contacts on your GPU or RAM (I just did it 5 minutes ago on a computer that wouldn’t start, and hey, it’s back up)
Preferably a white eraser, not the infamous blue and pink one (too abrasive) and while you're at it, get a can of compressed air to blow out the ports of your GPU and RAM, it can't hurt
happy erasing everyone, I hope this helps you

Hello, after putting it to sleep, I couldn't turn the PC back on, so I forced it to shut down and restarted it, but now there's no display and no beeps. The graphics card and fan are excessively loud. As advised, I moved the RAM around, but nothing worked. However, disconnecting and reconnecting the battery solved the problem. THANK YOU, ROVERS.

virtuose1 · Answer

Hello  I know the post is old, but I need information from professionals, so I'm reaching out to you.  Tomorrow, because it's late now and I don't have access to the laptops, but I have the same startup problem on 2 laptops that I pulled out; I use laptops very little.  I diagnosed the issue a few days ago before coming here as a dead battery or a CMOS problem, which, in my humble opinion, are the most serious leads before the motherboard or graphics card dies.  The problem is, even on the repair side, I'm much better with desktops than laptops, so I'm looking to find out where I can find these settings or the battery?  I'm hearing about the battery, the jumpers for clearing the CMOS?  I assume it should be located almost in the same place on all laptops, but if that's not the case, tomorrow I will provide you with detailed information because I'm lost when it comes to laptops.  Thank you Virtuose1
