Arite, well, i just finished my first major case mod. I took my Small Form Factor barebones PC and moved it into a G4 case (which looks pretty sick) but is quite tempermental. Whenever i boot it, it does its normal thing, i get into windows, it starts loading stuff, i can move the mouse n everything then POOF, it all goes away! the only thing I can think of is that it is rapidly overheating, but i doubt it becaus i still have the bottom half (it was bumping up against the power supply) of the old heatsink on there (fan is gone too). Would this make this drastic of a difference, turning a once stable machine into one that is unusable? I have searched my bios for a way to change the auto-shutdown temp, but I cant find it (the fact that i only have about 40 seconds to search for it doesn't help)
