no power to keyboard/mouse
Posted 16 November 2008 - 09:04 AM
My PC does not seem to have power to keyboard and mouse. Num lock or caps lock do not light up on keyboard. There is power to monitor but no picture. When I turn PC off then back on it starts up but no display. I don't hear any other boot sounds i.e. beeps when powered on. This seemed to happen overnight while computer was on. With cover off I can see and hear fans in power supply and other cooling fans running. I have not made any major hardware changes lately. I did update BIOS about 6 weeks ago based on issues I was having with random shutdowns, the update seemed to resolve that problem.
Things I have tried so far that have not helped:
1.) different monitor
2,) reseated memory sticks and video card
3.) Took case cover off and blew out dust (there was a lot of dust on fans, etc.)
4.) checked to make sure everything is plugged in that is supposed to be
5.) removed then reinserted battery on motherboard after waiting 30 minutes
6.) tried unplugging lead on motherboard for reset switch (twisted blue/white wire)
PC is a Gateway GM5478, w/ core 2 quad Q6600 (2.4 ghz), 2 G DDR2 SDRAM, 500 G 7200 HD, Nvidia 8600 GTS graphics card, 400 watt Delta PSU. Keyboard is gateway PS2 vista compatible, mouse is USB optical. Motherboard is INtel (shroeder town ) G33, pt #4006194R. OS is Vista 32 bit.
I would appreciate any help that could be provided to fix this problem, thanks.

First guess: Power supply. I would try a different PSU (temporarily) to confirm/refute.
Thanks, I don't have another PSU to try but I pulled the PSU out last night and will try to have it tested after work today.

He also said to check to see if fan on video card is running when power is on. I checked that and fan is running.
He also said pull out RAM and see if PC beeps at start up. I did that and PC beeped at start up. He said no beeps would indicate a Motherboard problem.
Anyone else have any ideas?
