Hey guys I came here about 2 years ago with a question about parts. This time around its a little different. Thanks in advance.

Computer specs:
GPU: Hd Radeon Msi twin frozr III
CPU: I believe it's a i5 550k intel
MB: ms - 7752 ver: 1.4 (z774-g45) oc genie II
Ram: mushkin black line enhanced 8gb sticks. I have 4 filling all slots.
Psu: evga nex650g 650 watts
HDD: a data sp900 256gb ssd

Basically what's happens is I will have the computer running but if I shake the table It will freeze causing me to have to reset the computer. But when I reset the computer it starts to boot up but stops and turns off, only for it to turn back on again and repeats the process so I cannot turn it back on.

I let it sit for about a day and turn it on fine, careful not to brush against the desk, but a slight move causes it to happen again and I cannot turn it on due to it restarting itself Over again.

At first I tho it was because the processor was overheating cause the heat sink needed to be cleaned so I de dusted it and re applied thermal paste. I have done this twice so far but it doesn't seem it have had an effect since it wouldn't work until I had waited the 12-15 hours.

I have scoured the internet looking for possible ways to fix this problem, I don't know what to think since it has started up fine until I hit the table, then it stops working for 12-15 hours. I'm completely stunned I have no idea what to do, any help would be greatly appreciated.

Also currently the computer will not start. I have taken everything off except for the CPU. So that means HDD is not plugged in, same with the GPU. It's only CPU and motherboard right now and it is doing its start then turn off thing right now.

I'm assuming the Computer is on or somehow being moved by the table when it is tapped/shaked. Considering this it sounds like something is loose or being shorted out due to the movement the question is what? Considering your system is stripped down to the barebones we are left with the PSU, CPU, Motherboard, and memory as your culprits. The CPU is unlikely though.

For a quick test you could try reseating your memory and checking for any bulging capacitors on the motherboard.
 


Pretty sure you've already tried this but just thought I should throw it out there. Are all your connections secure?
 


I'd try it without the GPU and only 1 stick of ram in the system just to hopefully narrow it down a bit.
 


Does it (the PSU) still turn off when you do the paperclip test? (Make sure nothing is plugged in for the paperclip test)
