As should have been inferred from my previous post, that PC is not mine. Owner picked it up a few hours ago.
Then I got a call that the screen was getting no signal. Turns out the PC powered up but didn't POST.
Huh. Internal clock battery?
I talked him through a process that got it on and him logged in and he was happy. Less than an hour later, he called with same problem. He also mentioned that after taking the side cover off as directed for examination of the POST code LED, he somehow was severely shocked, in a room with no carpet and average humidity.
Whoa! The earthing of that computer is faulty. Revise it, and revise that the building has good earthing. I have seen places where the earth was faked: there was an earth wire, but was not connected to an earth rod. With missing earth, the chasis of the computer can float at a mid voltage of mains. Say, mains is 220, the chasis is at 110. It is a side effect of switching power supplies combined with EMI filtering. Does not happen with all PSUs.
When I first got it here several days ago it wouldn't POST. I pulled CPU, repasted it, blew out the dust and tar, put it back together, and had no trouble with it over several days.
I would go there and check with a voltmeter. - -- Cheers, Carlos E. R.
