I have a computer that I built from scratch couple of years ago. I've had no bother with it till now.
When I go to switch the computer on, it only stays on for a second then turns off. I've went through everything, cleaned everything, unplugged everything and plugged them in one by one.
What I have found is when I unplug the 2 4 pin CPU power connectors the computer will stay on but won't hit POST screen obviously. If I take the CPU out and leave the CPU power connectors in, it powers up still.
Does this mean that my CPU has gone? Or is it a possible Power Supply issue?
Still have the same problem, tried another power supply, and the computer stays on but nothing on the display, no BIOS screen or anything, I thought I would at least get that, This power supply was only 20 pin ATX tho instead of 20+4.
Anybody have any ideas on what could be the root cause of this?
