EXTREME DISTORTION! My computer does not respond to power/restart button.

Just put together my new computer from individual parts. Started just fine, loaded up windows, was able to format new hard drive, then install first part of windows instalation.

When the secound windows xp home install pops up it starts installing, then the screen extremely distorts and the computer becomes unresponsive, power and eject button do not even work.

Computer needs to be shut down with the power switch at the back of the computer.

By the way: I've switched out my hard drive 3 times, had 3 different video cards, 6 pieces of ram, two different versions of windows (One with SP2 and one without service pack 2).

Any suggestions would be helpful.

.!.!.Thanks in advance.!.!.

Hello and welcome to techspot

what are the specs of your computer

Processor: Pentium D 950 3.4GHZ
Mobo: Intel D975XBX
RAM: (2) US modular 533 MHZ 1 GB
Hard drive: 250 GB Hitachi Serial ATA-300
Disk Drive: NEC DVD-CD-Multidrive
Video Card: BFG Geforce 7600 GT OC

Since you've pretty much eliminated most of the common problems, I'm leaning towards a bad power supply.

What are the specs on your PSU?

My PSU shoulden't be a problem as it is a 500 Watt unit and has a 12 Volt ratting of 30 Amps, 3.3 V of 25 Amps, and 5.5 Volts of 35 Amps

Any suggestion to try?

have you tried donig a barebone startup


take out everything exept Leve 1 stick of ram, 1 cd drive, 1 hard dive, Mobo,cpu

try to install windows and see if you still crash

good luck

Brand?

Only thing else you haven't eliminated is

1)CPU
2)Mobo
2)Optical drives

i can cvery well be one of those you havent checked, i would try the cd drive first then try swaping out the mobo

Im returning the mobo today, to see if that makes a difference.

power supply

i know this would be totally noobish but is there any chance that the power supply is not properly seated in all the correct ports. that happened to me a wile back and all that happened was the power supply came loose
