Crashing with physical contact

Especially when connecting a USB or SATA device in the front panel. Never use the rear, can't comment on that.

Usually, I get a black screen with red streaks. Sometimes it jsut stops responding except for the mouse, until it restarts a few seconds later. Other times it just restarts.

It crashes even in BIOS, locking up or restarting.

I tried:
Removing my UPS (with "pure sine wave") and connecting to a normal power strip.
Running ground from a molex cable to the motherboard tray.
Re-mounting the mobo and all accessories, a few times.
A new power supply (was HCG, now Seasonic Gold.)
Letting memtest run for about 7 hours. One stick of RAM failed twice in the same pass, on a different board. However, it passed every time on the machine in question.
PRIME does not fail. I never crash because of playing a game.
Swapping every part except the motherboard, into my other machine (both AM3). . . . When I did this, I couldn't get either machine to crash.
I DO have paper washers around my screws.
Secure Erase
Windows Reinstall

I used to get 242 for 3.4Ghz. After swapping the parts and putting every thing back where it belongs, I can't POST @ 230 or load into windows @ 220.

What is going on?
 
does it crash because you just added load to the system, i.e. plugged it in
or does it crash if you just touch that area of the computer?

If it's when you plug something in, i'd say it's the motherboard
 
It crashes when I physically move the tower.
It also crashes when I connect a USB device, but I'm careful not to move the tower.

I just built my PC in a box, no where to short - and it still can't OC any more.

I suppose the mobo is just bad. Maybe the physical movement caused solder to short.
 
If it crashes when you physically move the tower, that means it's definitely a connection/short problem. Check the connection very carefully from the USB port to the MoBo.
