Système arrêté

Thank you for your response, I am in the setup, maintenance, load default. I have "continue" and "save/exit" and I have the following message:
1Jbod device found
Bios installed successfully
Strike .........
System halted !
What now?
Thank you, dear.

"1Jbod device found": is that exactly what you have?
You need to choose save and exit, but I have to admit I've never seen "system halted" before...
If it's a tower, you should remove the BIOS battery for a few minutes... obviously with the machine turned off and unplugged...
Check in the BIOS, and in boot if it's really the hard drive that's first... if not, set it to the top line.

Thank you, I just removed the battery. There was a message saying that a problem was detected and Windows was shut down to prevent any damage to your computer... I restarted and the message comes back and says that I need to check for viruses, remove all newly installed hard drives (there are none), and verify that the hard drive is properly configured and installed.
And now it gets complicated: run CHKDSK/F to check for damage on the disk and then restart.
Technical information:
stop: 0x0000007B ..........blablabla

What should I do now?
Thank you.

I specify that I turned it off, removed the battery, waited, turned it back on, got a message, restarted it, and after that the message described above.

If you ignore chkdisk, does it start or not?

Try to start in safe mode by tapping F5 or F8... as soon as you turn it on....

I just restarted in F5 and "start Windows normally"
and the result is a blue screen and the same message
:-(

in safe mode the same

In the list, it should offer you chkdisk... otherwise, choose "command prompt, then look here:

be careful, there is a space before the /

Thank you Poupougne
But nothing works, no matter how hard I try to restart in every possible way, safe mode, command prompt, etc., I always end up back at my blue screen with the CHKDSK/F alert.
I’m afraid there might not be a solution
Thank you very much for taking the time for me... and no matter how I start from the bottom to climb the mountain, it’s steep....
Thanks again

For the chkdisk, you need to add C:
chkdisk c: /F
Is that what you did?

So you never have the cursor in the top left by itself?
Since it follows the installation of wireless keyboard and mouse, I assume you have removed them, BUT if you don’t reconnect the keyboard with the PS/2, the ones with the round plug often purple, it can cause this kind of problem...
Otherwise, just remove your hard drive entirely, it should boot to the BIOS and tell you there’s no HDD... then turn it off, put the HDD back and start again...
Do you have the installation CD of your OS (XP, Vista...)?
If so, you can set the CD drive as the first boot option, insert your CD and confirm, it will boot from the CD, then we can see....
