Computer refuses to show video.

post #1 of 5
Thread Starter 
I tried to add a new wireless pci card to my computer today and now it won't show video at boot. I've narrowed it down to a cpu or chipset error thanks to the led codes on the mobo. Any suggestions on what to do? I've tried on board video and my card I've gone so far as to disconnect everything save the psu and mobo and ram. No change.

I think it's due to not having good thermal paste but no store near here sells it.

When you installed the pci card, you didn't bump your graphics card (if you have one) did you?

Also what happens when you remove the wireless card, does video come back?

Try resetting the CMOS. There should be a little jumper on the lower right hand side usually, you need to jump the piece of plastic to the other node, wait 10 seconds then put it back where it was originally. Something may have gone screwy with the BIOS when you were taking it apart and its not properly detecting hardware.

I've had this issue with my PC before, that usually fixes it. If it doesn't, try changing to DVI port (or which ever video port you're using to send video to your monitor) your monitor is using, it's not uncommon for ports on a graphics card to go out, one of my DVI ports recently went out.

Ram also has this effect. take all ram out and put one back in and see if she boots. if she does keep adding the ram until you find the culprit.
