Hi.
One of my friends' PC was working fine, when they tried to open Youtube and it turned off as they said. Since then it's stuck in a boot loop before even POST. When I try to turn it on nothing appears on the screen, it doesn't even notice that the PC has been powered on.
First, I removed all the USB devices. Then tried plugging off the PC, reseting CMOS, CMOS battery, pressing power button for 30 sec. Then I removed the GPU as well and left only 1 RAM of 2, tried in different slots. Then I reseated the CPU, put new paste on it, reseated the cables. Now there's only the PSU, MOBO, CPU and RAM put in.
If I remove all the RAM's, it beeps signalling that it's missing, however, if I put one back, it gets back to the loop again.
What could be the problem? Mobo, PSU, or CPU?
