Screen "twitching" for no apparent reason

[Massa]

i just got a new motherboard (MSI k7t-turbo LE) to replace a defective one, and ever since installing the mobo, my screen has been "twitching"... think about what it looks like when someone is cold and they're shivering, and you'll have a good idea. most of it is occuring at the top of the screen. I'm running a Visiontek GeForce2 GTS, and have 512mb of pc133 ram. anyone know what's going on, it's making me slightly nauseous

In the rare chance that you don't have an AGP video card, switch the PCI slot. Also, I would check the power supply connection--probably not that, but it wouldn't hurt. And make sure your moni is plugged in securely to the card. Don't want to insult your intelligence, but just thought I would mention what I would do.
