No video output from card or integrated

post #1 of 7
Thread Starter 
I decided on a whim just to pop out my video card and give it a dusting with a can of compressed air. Did so, hooked everything back up, and now i have no video output. I know that i didn't do anything to the videocard because I switched it out for another one and that didn't help either - plugging the monitor into the onboard vga port produces no results as well. What the hell is wrong? everything was working just fine before i took the video card out. any and all help/suggestions would be appreciated..

I always reset my CMOS and reseat my ram when stuff like this happens. It's worth a shot.

Are you getting any light or beep codes?

unfortunately, the motherboard i'm using is so 'budget' that it doesn't have an LED indicator or onboard speaker. i reseated the RAM, but i haven't tried the CMOS. i'll give it a shot right now. Everything appears to start up fine, all the fans, pump, hard drives, etc.

i can't figure out what's going on - i switched the cmos jumper to the two pins on the right and the pc won't turn on at all. as soon as i remove the jumper from that spot, the computer turns on for .5 seconds and then goes right back off. placing the jumper in the original spot yields no results either

I had a similair problem when removing my graphics card for cleaning. I removed the gpu again and blew out the pci socket with air and this seemed to cure the problem and the system booted. Make sure you have not dislodged your memory when you removed the card as this can cause the problems you are mentioning too.
Good luck.

Does your motherboard allow you to start the computer with the 'clear cmos' jumper bridged?

Edit: I think you'll find you're not supposed to try to boot it with the clear cmos jumper bridged.

Switch off the power to the PC, flip the battery out, bridge the clear cmos jumper for 10 seconds, remove the jumper and replace it in its original position, then replace the battery, turn on the power and try to reboot.

Clearing the CMOS fixed the problem - thanks for the help.
