So I recently upgraded my system from a P4/Radeon 9800 pro to a amd/7800gt . I installed the new mobo/processor/vid card but used my last systems HD's and CDroms. I uninstalled all the ATi drivers but when I try to load windows now the system restarts and I get the safe mode prompt. I dont really know what other information I can give that would help but if anyone can think of anything please let me know. Thanks.
