Black Screen

by Doug Allen / May 1, 2004 9:14 AM PDT

I have a problem where i will be working away at my pc and for some reason the screen just goes black. The PC doesn?t reboot or crash and is still running, but the only way to fix the screen is by hitting the re-set button. On rebooting no error message comes up, the problem is especially bad when i try and play a game (Command and Conquer Generals) the pc will load the game and as soon as game is about to play, the screen will go black (also happens with other games) I have run several different memory tests and all show no problem. I have had a couple of error reports after crashes saying that i have bad memory sector and need to run the test, but its a no show. Does any one have any ideas, could it be a driver conflict, there is a D bracket with 4 diagnostic LEDs on the pc but I?m not sure how that works, Any help appreciated. The pc is operating on xp with 512 mb ram and an onboard G force 2 graphics card, could it be the onboard Graphics, all drivers are up to date

When this machine goes black, detach the monitor and connect a different monitor.
I have had several LCD screens with this behavior that I had to return for repairs.
It is a possiblility.

It goes without saying really, you must get the latest graphics card drivers (v56.72) and make sure you're using the latest AGP patch for your motherboard, and ensure you're using the latest version of DirectX. I occasionally get the same thing happen with my nVidia FX5200, but the system comes back up after less than a second and Windows doesn't crash. The situation certainly improved after I installed DirectX v9.0b. I consider it is something to do with a timing and/or frequency mismatch that only occurs every so many cycles when a certain set of other factors occur simultaneously. No, I have found a fix, though as I said, it happens less now I'm using the latest drivers. My graphics card is an AGPx8, though the slot it's in is only AGPx4 capable, I think this a contributory factor in my case. Regards

While many will tackle the software drivers and such, when I see this, I may remove the case cover and ask if it gets better or same to sniff out a heat issue.

Have you run DXDIAG, it may give some clues. You say "the black screen" happens especially when running games, which sort of implies the game(s) may be selecting a graphics card display mode, or refresh rate for your monitor, that neither actually supports. Though when it happens and you're not running a game this doesn't apply, damn! Regards
