Hp pavilion gaming desktop power trouble

[Twingrove12]

My hp pavilion gaming desktop at random shut off on it own. Now when I try to turn it on the front flashes green then nothing and no boot up. I have to un plug the power and plug it back in for me to try to turn it on for it to do the same thing. When I do it one fan turns for a quick second and then nothing. I have checked over every wire and looked at the boards no burn marks, I have removed the memory cards and put them back in. 

thanks for the help

Hi

This sounds like a power supply problem or a component short, the short causes the power supply to shut down. Because you then have to unplug AC power to drain power and reset the system.

I would contact HP Support if you are in warranty at:

Have a local PC tech diagnose the bad component if you are out of warranty.

First verify all connections to the motherboard are good. You would have to try a different power supply and systematically (one component each time) reduce the PC to minimum component connections, RAM, monitor, keyboard or mouse only. Try each stick of RAM in each memory socket. Then you may need replacement components to test for the bad part. You have found the bad part if the PC starts after removing one of the components.

Last, you would need to replace the CPU and then the motherboard. Very costly. This is why it is often cheaper to have a local PC tech find the bad component.
