(I would set the difficulty to 500 points, but i do not have enough points for this. Sorry! But please still awnser)
Hello. My name is Tom Forbes.
I have had a HP pc for about 2 years now.
I was in my study with my PC recently, and i needed to get some work of my Pen Drive. Now i have 4 USB ports, all filled with;
Speakers (powered off USB)
and extra slot for my iPod or memory stick, always filled.
I just put my memory stick in, and a balloon popped up on the Icon section of the taskbar, saying somthing along the lines of:
Usb port 'somthing' has taken to much power"
(i cannot remember all of it, because i did not pay it to much attention).
As i read it, the screen started flickering (it was a CRT one), and going realy slow. i moved the mouse and it moved in jolts, sort of Start, Stop, Start, Stop ect.
Then the screen went black. The PC was still on, but there was no display. I have a grpahics card that i brought, so my first assumption was that that had blown. i took it out and tried again, but same result. Nothing.
I have taken it down to a local 'computer guy' down the road, who works for a company called Systematic.
They had a look at it and poked around with it, but were stumped. They had no idea what was wrong with it.
I have tried:
New Graphics card
New Hard Drive
The only clue is this:
I set in the BIOS that when the power is cut turn back on as soon as it is restored. It no longer does this.
I have taken the Hard drive out and tried it on another PC, and it is flawless. No damage, no data loss.
I think it might be the motherboard, but i wanted to know if anyone out there has any ideas.
p.s i will be ENTERNALY in your debt if you can awnser this question.
