PC Crashing - Update

[Ruger22C]

New Thread for clarity.

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.



These are the solutions I have tried:

Samsung RAID 0 ---- SSD Agility 2 (Used separately(disconnected), still crash.)

PSU:
Antec HCG 750 ---- Seasonic Gold 750

Power Source:
6-plug strip ---- CyberPower 810w UPS (Appears Good, other PCs do not crash.)

Optical Drive
DVD-RW (Known Good) ---- DVD-RW ---- Blu-ray

Note on Outlet/Power Source
Second, third, fourth, and fifth PC Never crash like this.

ever crash like this.

As it does this regardless of the hardware installed, and despite connecting the other PC's to this same wall outlet without incident, what you're describing sounds like either a ground fault or ESD. I'd test that outlet/powerstrip/UPS for continuity and voltage, or connect to a different outlet entirely to see if it acts the same.

If you're moving around on a synthetic carpet you're body is building up a static charge. If you're not first grounding your body by physically touching a well grounded part of the case, or by wearing a heel or wrist type grounding device, before connecting/disconnecting anything, ESD can be a PC killer.

You said: "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." Electrostatic discharge can jump a considerable air gap (ESD is very high voltage).

Why did you start a new thread? I gave you the same answer.

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.

Fixing the ground may be a real pain.

...but may be your only solution. If you are up on the 2nd floor, you can run a ground wire down the outside of the structure and into the ground (securing with a reasonable grounding rod,) or attach it to the building ground/bond wire if it's nearby.

If the building has grounding issues, I'd be looking for the refrigerator, the TV, etc... to start having issues.
