From: Paul on 10 Dec 2009 18:44 I had a similar thing happen about 4-5 yrs again, with a P4 system I had. I brushed my arm against the case one day, and felt a tingle. Which, I knew didnt sound right. What happened in my case, was not only was the power earthing the case, it was also frying the CPU (the system kept crashing), and it was screwing up the videocard. If I turned it off and disconnected the video cable, and touched the pins, they were live I found out what the prob was after. The earth wire had come out of the power point, it was plugged into. Lucky for me, I got onto Intel, who replaced the CPU for free (the fried CPU had to go back to Malaysia to get replaced). I used a lower spec CPU, in the meantime. The replacement took 2 weeks to come back. I had to replace the mobo tho.

My bad. I should have looked at the pictures. Strange that the chip doesn't unsolder itself from the board if it gets that hot! -- bz please pardon my infinite ignorance, the set-of-things-I-do-not-know is an infinite set.

I'll stand aside in light of your experience here. However, in the hope of not making things worse, I'd be very hesitant to suggest that someone just pull components out of a circuit and hope it still works properly... William |
