I am working on a pc right now and its being a pain. The PC keeps locking up totally (requires reset), it seems to be happening when accessing a cd, although its totally random, yesterday i installed Doom 3 on it no problems, today i played an avi movie (off cd) and it froze after 10 minutes. Installing Office 2003 it froze on autoplaying the cd.
The PC came in first of all because it wasn't booting into windows (missing systems file) and the customer wanted the PC to be formatted, so i did a full format, re-installed XP and the PC froze a number of times installing software and drivers the customer wanted putting back on the PC. So i tried new RAM and it seemed to fix the problem. A week later PC was back again with the same error (missing system file c:\windows\system32\config\system), so i repaired the mbr this time and now its running into windows fine but still freezing during cd access.
Windows XP Pro
Athlon 64 3000+
1 Gig Crucial Ram
Maxtor 160 GB SATA Diamondmax
Gigabyte K8VT800 Pro
Sapphire Radeon 9600XT 256mb
Cobra Gaming Case with 450w psu
There seems to be no CPU overheating issues (43oC).
Not sure what to try next, any ideas?
