hello..

It started with the comp hanging and not responding. I do not have a restart button, so i have to power down the UPS each time it hangs. The mobo has a CPR hard boot feature, that worked the initial couple of times. but then it started hanging more often. then it started hanging at boot. then it stopped booting. I tried re-installing the RAM, tried reinstalling the GPU, tried without the GPU. sometimes it boots and even when it does, after some use, it hangs again. other times the mobo lights up, cpu and gpu fans start but no signal to the screen. same issue even without GPU. Any idea what could be the culprit? mobo, cpu or ram?? or is it the smps! ? i'm pretty sure its not the GPU, hangs even with the on board graphics. Kindly help.

I had a problem similar to yours. Try clearing the CMOS on your motherboard. First, remove the CMOS battery, then jump the two pins next to where the battery was. Let the two pins stayed jumped for around 5min, then try to turn on!
