Darn - I bet he's sold it by now.
MY two cents though.
SEVERAL things could have caused this.
I would opt to think its one the three core components.
Faulty RAM, Bad Graphics, or a dying mobo.
Before we start on the ram, do you have by any chance, and old generic PCI Graphics card? (provided your sys has PCI
) - that would be nice to use to eliminate your graphics card as a problem.
Memtest is extremely thorough - but that thoroughness isnt always in place by default.
Did you change any of its default settings?
I dont know the menu's offhand now, but you should look for something about the test range - and but it at "bios-all", and look for another option that says "test all memory" or something to that effect.
Those options are important.
Your CPU is fine - so long as your PC is still booting ok.
Question though - are you sure it was fine to begin with!
(just because a PC boots, doesnt mean a CPU is golden)
You should also take the time to clean your RAM slots.
Brush them out with an old toothbrush, then do it again - with the toothbrush wet with rubbing alchohol. (make sure to let it dry)
Clean the contact of your RAm with an erasor. EVEN if.. they dont look dirty, give them a thorough rub.
Then clean the module with the alchohol toothbrush.
I would also suggest that you reset your bios before you begin your venture.
AND FORMAT YOUR HARDRIVE
do tell how it goes.
