Overclocked GPU - Need help

[Kidge]

Basically i have stupidly overclocked my 5450 within AMD's windows software (catalyst?) to its highest settings and hit test which caused system failure and now won't let me reset the amended settings. Windows boots and allows me to log in just doesn't allow me to revert settings.

Is it a case of removing the graphics card and then boot using mobo output to then change? Such a school boy error due to boredom and no sense at the time!

Any help would be appreciated

Thanks all, will try both solutions when home from work this evening and will post update around 6pm.....

Thanks for both suggestions!

Jon, unfortunately the registry file wasn't available on my machine (assuming I installed something different?)

djshauny, I was unable to test your idea (didn't have the time or resources to download driver sweeper) so i opted to just do a fresh install of windows. I suppose it was about time.....

Without creating a new thread and becoming annoying. Would anyone have any recommendations on how I could set up my machine to be able to play Dirt3?.

Currently, when I try to run Dirt the graphics lag/judder an unbelievable amount. I'm not really an avid PC gamer but it would be nice to play it once in a while.

Setup:

GIGABYTE GA-880GM-USB3
AMD FX4100 @ 3.6Ghz
XFX HD5450
4Gb RAM
500w PSU
90Gb OCZ Agility 3
750Gb WD Caviar

EDIT: Will be OC the CPU again when I get a new PSU, read some comments and don't trust my current budget PSU.....

Cheers devrij I'll give that a try. If i get into it a bit more i think I'll just upgrade my GPU as that seems the best route.

Also, one more quick question......Which is better performance wise, the onboard HD4000 graphics or the HD5450 card?. I would have thought the card but I cant find any benchmarks when searching to confirm that?.
