I have a PC which is exhibiting strange graphics artefacts on startup. It manifests as thin blue vertical lines appearing, sometimes on the BIOS screens but always on the "Windows XP" loading screen.
After that sometimes Windows starts but the screen display is completely corrupted. Or sometimes it fails during reboot with PAGE_FAULT_WITHIN_NON_PAGED_AREA message and then reboots immediately.
I have removed the graphics card and cleaned off the dust and cleaned the connectors but this didn't make any difference.
I opened the case and left it open in case it was a heat problem, no effect.
The problem happens immediately, even after the system has been off for a while.
I checked all the fans in the system and the CPU/Gfx/chipset fans are all spinning and not making any strange noises.
Does anyone know what the above symptoms might point to? Is it possible to say with some degree of certainty that it is the gfx card or might it be the motherboard/memory/something else.
The PC is quite old (4 yrs+).
- Motherboard: Asus A8N-E
- CPU: AMD 3700
- Gfx: Nvidia 6600 GT (Link)
Though even if the Gfx is the problem I'm not sure I could buy a compatible one these days!
UPDATE: So it was the Gfx card. Replaced it and now everything is fine.
