I have the same problem, but it happens sporadically; I could be doing something else, not even on the computer, and everything shuts down on my phone....
I'm on the internet as usual and then it stops! No warnings. It doesn't happen at particular times, but a bit anytime; could it be the graphics card too???

I have the same problem, my screen turns off by itself like that when I'm watching a video or chatting with people :/
Is it really the graphics card that's messing up?

I have the same problem, the screen goes off while the computer is on, and it says "no input signal."
This issue occurs intermittently, but especially when I watch videos on YouTube, particularly HD videos.
I have to restart my PC by turning it off with the power button.
I have 2 DDR2 memory sticks, and when I remove one of them, the screen of my computer doesn't turn off as often.
Moreover, when I put both sticks in, the screen often doesn’t even turn on, or if by miracle it does turn on, most of the time I can't even get to the session opening before the screen goes black.
However, with 1 stick of RAM, it works normally, except when I watch HD videos or visit sites with a lot of flash ads, then it turns off, black screen and the PC still on.
I have already tried with new memory sticks, same issue. I have 4 slots for sticks on my motherboard, I can place them in any slot as long as there is only 1; it works. As soon as there are 2, it doesn’t work anymore or only for a few seconds.
I also want to point out that I’ve tried the memory in dual channel and single channel, and the symptoms remain the same: 1 stick works quite well except for the HD videos or a few random cut-offs, and 2 sticks really don’t work at all.
I have no idea where this problem comes from; if anyone has an idea, thank you.

My screen turns off after 2 to 3 minutes of use. I bought another one and the problem is gone. Conclusion: defective screen.
I had the same problem, my graphics card connectors were disconnected. Check if you may have unplugged them and forgotten to put them back.
I also had the problem of the screen turning off while playing or watching a video. But I solved the problem by updating the drivers for my video card; I unplugged and plugged it back in. And now, everything is great.
My card is a Nvidia 220 GT.

Good evening,
I have a bit of the same kind of problem.
I bought my computer almost 2 years ago. Since then, I've been playing The Sims 3 along with a lot of expansions and kits. Everything has been working fine for months. However, for the past few weeks, when I launch the game, after about 3 minutes the screen shows "no signal," but the tower remains on. I have to reboot.
I have several games that demand a lot from the computer, like The Sims Medieval + Noble and Pirate, League of Legends, Counter-Strike, etc., but the bug only occurs when I launch The Sims 3.
Avast detects no viruses. I have defragmented. I uninstalled the objects I had downloaded. I completely uninstalled The Sims and then reinstalled it fully and partially (without the expansions and kits). The problem persists.

Well, given that I've been playing with it for almost 2 years now, the card must be quite powerful; otherwise, the problem would have already shown up.
Anyway, I changed the type of power supply for the screen and it seems to be working. Thanks in any case for your response.

Hi, I think I have the technique to fix this issue
You just need to start the computer and spam F9 to reset your computer as if it were "coming out of the factory"
The reboot takes about 1 to 1.5 hours, depending on the computer
The most recommended but also the most annoying thing is to leave NO trace of your "old" computer (before the reboot) because the problem could very well come from some software or any file
But still, ALWAYS get the opinion of a specialist (your after-sales service, for example)
I warn you that this technique may not work if the problem comes from your hardware (broken graphics card, faulty fan)
Anyway, good luck and let me know if it worked!

Hello everyone,
I had the same problem as you after changing my graphics card: switching from an ATI Radeon HD 5770 to a 6950.
Windows was stable, except in games where I lost the display after less than a minute.
Linux was stable, except when watching movies where I also lost the display after a variable amount of time.
In both cases, I sometimes had to wait before restarting the machine lest I would have no display.
I first thought it was a power supply problem. I replaced my 430 W PSU with a 750 W one. It didn't solve the problem.
Ultimately, the solution came from changing the outlet. Until now I was connected to an electrical outlet WITHOUT GROUND.
Since I connected to an extension cord plugged into a bathroom outlet WITH GROUND, I haven’t had any problems.
For your information, my parents had a similar problem with another machine. It would systematically go into standby until we thought about the ground connection. Since then, they have also had no issues.
So you might say: before, with the 5770 it worked. I don't have an answer except that maybe the problem is more sensitive when the consumed power increases.
In summary: for those who have this issue of display loss or instability (which was the case for my parents where the failure was more global and concerned the entire PC going into standby) and whose machine is not plugged into an electrical outlet with a ground connection, try PLUGGING INTO A GROUND OUTLET.
Good luck,
Steven

Hello everyone.
I've been playing a PC game for a month without any problems, then all of a sudden I can't play for more than 15 minutes without the screen "going to sleep." I don't know why, please help me. Thank you.
