I'm fixing a relative's computer, it's a VAIO desktop computer, specs here :
I understand no hardware has been added/removed, so the specs should be fairly accurate.
The problem in question is this :
PC starts up normally, goes to screen with Windows logo and loading bar, the bar freezes for a moment, then unfreezes, the screen transitions into a black screen , and it hangs there, as in, the CPU stops working completely and it doesn't respond to anything.
I've tried the bootup menu, but the only option that works is safe mode. Using that, I've tried system restore (many times, from dates of 1 week ago to 1 month ago), but Windows XP still hangs up while booting.
The owner of the PC is not very computer-literate, so getting specific details of what went wrong from him would be too hard. I've tried looking around in Safe Mode, but there's not much to see. No suspicious running processes (obviously) and no suspicious entries running at Startup either.
Is there anything else I could check/do from Safe Mode to solve this problem without resorting to reinstalling the O.S.?
