Computer Desk Frys PC!!

This is the only forum that seems to fit with what I'm about to post so here goes...

A friend of mine recently bought a new computer workstation/desk which is made entirely of metal, and has plastic wheels which in turn is standing on a carpet. After a few days of using it he started having problems when trying to bootup. He says that sometimes when he turns the pc on, it would work fine for a period of time and then it would just lockup. It could be as little as a few seconds into the initial POST screen and it would lockup. Other times he would be able to use his PC for a few hours and then find it locking up.

Regardless of how long it took for his PC to lockup he said that he wouldn't be able to use the Reset button to reset and had to resort to flicking the switch on the back of his PSU before he could power up again.

A few days after that he found out that both his harddrive and his CD drive stopped working. He bought them round to my house to verify it and they're definitely dead. So he had to buy a new HD and CDdrive and reinstall everything again.

All was well for a while and then I found out the other day that his PC fails to even boot now. The PSU fan comes on but nothing else. He doesn't even get any beeps through his tiny case speaker. The new HD doesn't power up anymore and the new CD drive is also broke. Once again, he had them checked on my PC and sure enough his new hd and cd drives are dead.

So we took every thing out of his pc and just left in the following devices/cards:

Mobo
Chip
1 stick of memory
Floppy drive
Video card
Keyboard
Monitor

On a normal working system, the setup I just described would still work albeit it would only reach the part just after the POST screen and then request the user for a boot disk. However, my friend's PC still refused to boot even when setup like that and his not too happy about it

He has a desktop case and has since noticed that part of underside of the case, and also part of the top as well, actually makes contact with the metal workstation/desk. He's thinking that his PC has become damaged possibly through some kind of power surge or maybe even static whenever he used to hit the power button on his PC. He reckons that some kind of current would have traveled through the bottom of his case, round the metal workstation and then back into the PC which ultimately lead to other parts of his PC frying.

Is such a thing feasible or is he just going stir-crazy cos he just blew his computer?

? If it's assembled correctly, the case is grounded.

Have you tried other power supplies? :)

I would also blame the power supply, though I have seen static discharge to a painted metal rack with a pc on top cause a reboot with data loss on the hard disk.

I'm thinking like Gunbuster. Sounds like poor polarity in the wiring.

The case should be grounded, by being attached to the Power suppy, if it wasnt properly grounded then sure, it could fry everything.The fact that the hard drive and cd rom went first leads me to believe it was the powersupply. both of these, especialy the hard drive have shielding, the ram, motherboard, or one of the expansion cards should have went first if it was his desk. Could be wrong but I would definatly get a new powersupply to be safe

yes, if he keeps it plugged in, and he didn't cut the ground pin off the plug and his wiring is fine ti wouldn' be the desk...in most cases, it would be grounded by the outlet.

it sounds magical ... he should check into the magical hypothesis...
