I recently tried to boot my computer, but instead the monitor showed a check signal sign with the three colors. After reading I figured out it was the monitor's self test.
I've switched systems and my monitor works fine, so I figure it's not the monitor or cable. I reinserted the video card and it didn't work. I bought another video card (an upgrade for me anyway) and it still doesn't work.
Is it the motherboard? Powersupply?
I don't know if this helps but when I boot the computer all the fans start to run.
I've had this computer for two years now.
CPU : AMD 64 x2 4200 Manchester 2.2ghz
MotherBoard : ASUS A8N-E Socket 939
Old Vid Card: EVGA 256-P2 N564-AX GeForce 7900GT 256Mb PCI Express x16
New Vid Card: NVIDIA GeForce 8400 GS 512MB PCI Express x16
Monitor : Samsung SyncMaster 204b
Note: When I push the adjust button on the monitor it switches back from analog to digital a bunch of times then the screen turns black.

Were you able to try the video cards in a different computer? (I know that's not always easy to do.) I shouldn't wonder if the PCI Express slot went out. Not likely, but possible, I guess.
Having spouted all that, I must ask if you know if the most updated drivers for the video cards were installed?
-
No luck with switching the video cards out, my other system has a different slot type.
When I inserted the new vid card I didn't update the drivers, cuz I figured it would at least show up on the monitor.
Even though the drivers arn't updated, shouldn't i see something other than the self test on the monitor?
-
Agreed. You should get basic video function. I was just looking for another way to test the cards themselves, while I stated the idea that the express slot on the system board is/went bad. Being able to slot the cards into another computer would help.
It occurs to me to ask if your computer has on-board video you might try as an option?

Depending on the card you might get a VGA output or no output at all without drivers.
Didn't the card come with a driver CD ? ?
Don't rely on Windows to update drivers...especially video drivers.
