Crashing & freezing PC

[chiefoftwosons]

Hello,
My PC was a barebones kit. Everything worked but the V\C. I replaced it with a Nvida 9800GT, & every now & then the PC crashes or freezes up. Is this the V\C or something more?

Card or PSU. Post the specs.

try Clean uninstall the "old" driver and then reinstall new driver...
