What would cause this?

[AxiOn IXI]

Not very often.. but it still happens. My monitor will just lose the input signal. Especially if i run 3dmark, turn the monitor off and walk away to let it run in a loop, when i come back and turn the moitor on, it gets no signal. Also, while just browsing the web its cut out before.

Any ideas?

Sounds like your trying to run a synch speed that your monitor does not support. Try downloading a monitor driver and then selecting the fastest sped that driver allows at whatever resulotion you run.

Otherwise back down a speed or two until it does work.
