GA7N400 Pro (not Pro2) problem - advice requested
I would appreciate suggestions about a problem I am having.
The PC is based around a GA7N400 Pro mainboard with an Athlon XP2700 cpu. It has been used for about 2 years. Now, it sometimes won't boot (not displaying anything on the screen at all), or when booted, will crash some time later, usually when simply idling (i.e. not actually accepting key strokes or mouse input). When it crashes, it keeps the cpu cooling fan (and chipset fan, and case fans) running. After a crash, it definitely won't reboot, but "sulks" for a few hours or a day or so! I suspected originally that it was a video card problem, especially as its cooler was choked with dust, but the cleaned-up Ti4600 (4X) card works fine in another PC, and the problem PC exhibits the same (no boot) behaviour with a different card. I have put the hard drive into a different PC as a "slave", and run a virus check and other diagnostics on it. The problem PC won't display the pre-boot screen without a hdd present either. (i.e. I think I have eliminated hdd and video card as the root of the problem. Am I right to eliminate the psu, on the grounds that it keeps the fans spinning after a crash? It may be my imagination, but the problem seems to have occurred after a Linksys 54g wireless network card was installed - although taking it out hasn't cured the problem. It seems to me that the problem must lie either with the mainboard or the cpu. Can anyone suggest how I might resolve which it is, please (and why that would give rise to the symptoms experienced)? I'm reluctant to dismantle a working PC to provide a spare cpu or mainboard, so the obvious solution (try the cpu on a different mainboard, try a different mainboard with the XP2700) has to be a last resort.
