I've overclocked my video card a bit too much and it has become unstable. So much so that after windows boots and gets to my desktop it can't stay up and running. I can't keep it going long enough to back down the settings. I'm using another video card right now in order to stay up.

How can I re-set the settings if I can't keep the system up?

Please can you post your graphics card make and model number - thanks.

It's made by MSI.

TI4200 - VTD8X

What software did you use to overclock it?

Does the system also reboot in safemode?

The MSI/NVidia software is what I used. It allowed me to set core clock, speed, etc.

But I fixed it and here's how for future record.

Start Menu -> RUN-> type "msconfig" -> then when to boot INI and clicked "Basevideo". Restarted the computer, swapped out the video card to the one I wanted and Windows starts with the most basic video settings available. I then went in and readjusted everything and here I am.

Thanks again for everyone's quick responses and help.
