Extreme Problem

Here's a really bad puzzler:

Computer 1: Gentleman brings his computer to me and says it has a virus. He hands me a piece of paper stating that it has the magistrate virus. No Problem. I told him that i could get the virus fixed in no time. Plugged his computer in, turned it on, and the power supply explodes!!. I unplugged it. And started trouble shooting. I have narrowed it down that the power problem killed everything in the machine by testing each individual component. Note that i tried his hard drive in another machine and it wouldnt detect.....

Computer 2: Another Gentleman brings his computer to me and tells me that Norton Antivirus came up with the option to repair an infected file, while he was updating his virus definitions. He said he clicked repair, finished the update, and rebooted the computer. The computer comes up with "invalid system disk." I inspected it and the partition on the hard drive was 100% usage of type UNKNOWN. so i fdisked and reinstalled everthing, and sent him on his merry way. He calls me later from home saying that his computer wont come on. He brings it back and I start trouble shooting. The computer received no power at all. I put in a new power supply. And removed everything else except necessities. Computer comes on. I put in each piece, one at a time, and turn the computer on to see if it works. I get to the last piece (hard drive) and the computer wont come on. So out of curiosity i hooked the old power supply back up with everything attached. Power supply explodes....

Summary: Here's what both computer's have in common:
Both came to me with a virus
I couldnt access data off of either one of the hard drives
Both Machines blew a power supply in the same manner
Machines were plugged into different outlets
The electricity in the building had been checked aftewards
and everything is working fine
Neither of them remembers what the infected file(s) were.



My Theory: Could this be a type of virus that somehow attatches to BIOS and raises voltages?? Could this be a freak occurrence despite the coincidences?? Could this be a script??
I have honestly dug into this for the past week and can find no real cause of the matter......Any ideas????

 

I would check the power in your building to make sure it's grounded correctly. Sounds mode like you are feeding 210 into the power supply or something. Is there anything else besides a virus that these two PC's have in common? There is no virus that can migrate to a power supply and blow it up. Sounds more like a cruel joke on somones part altho I would probably laugh if it did happen.

 

I had the electricity checked in the building by the electric company. Everything checked out just fine. Again here's what the computers have in common:

-Built by same person
-Same model power supply
-Had viruses that removed partition/wouldnt let me see the data
-Both killed power supply / hard drive (one computer fried everything)


Faulty parts??? Freak incident??? Or something else???

 

It's definately not a virus so I would look at the first 2 on your list.

-Built by same person
-Same model power supply

I would look on the internet for the power supply make/model and see if you can find any evidence of this happening to anyone else.
