Need some help with here please

I have just made a new system up for my wee sis


its a Shuttle SN45Gv3 Case/mobo/Psu with:

2x256mb PC3200
+2500 XP Barton Mobile
FX5700LE 128mb
Samsung DVD-rom/CDRW
8-1 card reader
Maxtor 80 7,200rpm 133 IDE HD

The problem:

When you touch the Alu case and another metal case you get a current flow through you. if you touch the alu case and a desk you dont. Both items have rubber feet so they will be isolated and not grounded I would think.

Should the PC do this?

I havent altered the case design so I dont understand why im getting a current off the PC. The other metal case isn't doing this so it has to be the pc.

Do i have to run a grounding cable from the pc to stop this current? Also isn't it a bit worrying that its doing it in the first place? I always though the PC power systems and Mobo was isolated from the rest of the case to stop this issue?

What you may find has happened is that a spare molex may be touching a piece of the case the is small enough to inside one of the molex pins. I had this happen once and it was a bit of a suprise to say the least (phew avoided the obvious 'it was a shocking experience gag )

Yeah but I though a molex and other connectors were sheilded to stop this happening? its not as if a bare metal wire is touching the casing.

Very strangle if that is the problem :S

Anyone else got a view on this?

well theres a guy in the office who built a silverstone HTPC up and hes got the same problem.

Check for any loose wires and also check that the ICE is screwed fully into the base of the case.
