computer wont boot

[Docretier]

My friend's computer wont boot, shows no sign of booting on power button push. i know its receiving power, as there is an led on the graphics card at the psu cable connection that is always on for some reason (assumed it meant unstable/no power as is with my card, but it functions normally). i removed the cmos battery, as there is no cmos break, and put it in again. it booted once after i did that but not again. would this behavior be indicative of corrupt/broken bios? or some other motherboard based issue? it seems to be motherboard, but i do not know.

Try taking the CMOS battery out and back in, and then in that one time you can boot, try flashing the BIOS.

try with a new power supply.  just because it "has power" doesnt mean the psu isnt fucked.

 

also, is this a new build, or one that was working fine a couple days ago?

Well is this a build with integrated graphics?

What are the specs of the machine?

 

Try taking out everything but 1 stick of RAM and testing that in each available slot. Take out the graphics card and use integrated graphics. Start from a minimalistic approach until you find your culprit.
