PC Crashing - And I'm lost

[icor1031]

The issue is this:
When I make contact with the PC: by hand, by setting side panel against case, or (especially) by usb or esata (even before it's connected!),
it: Crashes.

It used to give a black screen with red streaks, and then restart. Some times it restarts instantly. Some times it locks up. Some times it locks up as if the HDD was disconnected (the mouse still moves), and then restarts after a delay. Some times it locks up and restarts 5s later.

What else can I try? I am rather amazed at this point.

Thanks.

It sounds like a grounding issue.

How do I solve that?

How do I solve that?

Tear down the PC, look for any loose screws, wires, cables, standoffs, washers, etc, reassemble the PC again.

Just did that, Again (for another reason though).

Now what?

Tear down the PC, look for any loose screws, wires, cables, standoffs, washers, etc, reassemble the PC again.

 

[Dangman]

Reassemble the PC outside of the case with the motherboard on the motherboard box. See if the issue still occurs.

WELL.

I know the ground was not well done in my apartment, I've known that for months.

But I couldn't figure out why 1 PC crashes and the other doesn't, and I still can't.

... I ran an extension cable from the original house up to my PC, and so far even with creating a nice strong spark by rubbing socks on the carpet and then touching the case, 3 times, no crash.

Fixing the ground may be a real pain.

Thanks for your help, gents.
