Try another video card.
Hey all.. I'm posting from my old computer T_T..
Basically I was on my computer today and just went to do a quick restart only to restart it and have it not work. By that I mean it got to the loading screen for Windows Vista (Green Scrolling bar) then sits there for about 1-2 minutes only to blue screen. So I tried using my older HDD with windows xp loaded on it only for it to do the same thing (Cannot get into safe mode either) So I'm assuming it was a hardware issue of some sort. Tried using each stick of ram alone (1gb each).. No sound card, Video card in both PCI-E Slots, etc etc.. I'm pretty much extremely at a loss at this point and figured maybe you guys could help.. Here's my MoBo and Video Card info
-Asus M2N-SLI (nvidia nForce 560 chipset)
-Nvidia GeForce 8600GT 1gb
