Computer won't boot unless CMOS is Reset

Hello,

My CPU was working fine until the other day when I installed a TV/Tuner card, powered on, and installed some drivers for it. When I first put the card in and turned the system on there was a brief message on the post screen which said something about checking CMOS changes, I didn't catch it all. But upon restarting the system it would not post even though it had power, fans running, etc. No signal to the monitor at all.

After resetting the CMOS switch the computer boots. I since removed the card and drivers, but every time I restart, or power down, it won't post and start again until the CMOS is reset.

Any help for what is happening or how to fix it is greatly appreciated!
