Since a moment now, I can't start my Windows XP computer. The computer itself turns on fine, but the screen turns completely black just after I select if I want to start normally or in safe mode.
If I choose to start with the "Last good configuration" or in VGA mode, sometimes I get an error message saying that the isapnp.sys file is missing (or sometimes hal.dll), but even if I put back those files using the Windows XP CD, Windows still doesn't start and nothing works any better.
Here is what I tried so far:
- Fixboot command
- Chkdsk /r command
- Bootcfg command
- Reset the CMOS by removing the battery
- Removing/switching up the RAM
- Restarting in safe mode, last good configuration and VGA mode
- Unplugging the mouse and every USB device (except the keyboard since the computer can't start without one)
I don't really know what I should try next. I probably have some copies of my most important files and documents on my other computers, but I'd still really like to keep most of my stuff intact since I'm not 100% sure that the backups I have are up to date
Thank you in advance for your suggestions!
