Video Card: What's wrong?

by agavegrove / May 18, 2011 4:56 AM PDT

I have Win XP with a video card I installed (unk specifics, I'll add them when I get home later). It also is functioning as the soundcard. Lately when I run any online video, Windows Media Player, or try to browse multiple websites, my monitor says "No signal detected [from vid card]. Turning off" The computer stays on. When I cold-reboot the computer everything comes on normally. Also, sometimes when I'm playing music the audio cuts out like a CD skipping. Any ideas?

That's a sign of a well known issue with XP and DMA. I've written about it many times, and no longer write the long answer. All apologies but PLEASE DO THIS!

If you want to do more research, please do that.

Glad you didn't type the long version. The link seems to talk more about CD and DVD problems when being read. My problem is the monitor is losing a signal. I'm not actually playing any kind of disk.

The XP DMA issue and it's effect on the symptom is well known, been done how many thousand times and required no reboot.

May you find a longer explanation that will help you along.

Posting this should I need to refer back to this in the future:

Removed the vid card and the sinks were extremely hot to where they couldn't be touched. Noticed the hub of the fan had some discoloration consistent with heat damage. Reconnected the VGA cable to the original VGA connector. No more problems. Now to find the warranty information on that vid card....
