Well last night i think i toasted the media center. I am running vista 32 bit ultimate my hardware is a 3500 athlon 64 1 gig of kingston hyper x ram 6800 gt oc haupagge (sp) 250 tv tuner

Basically i was getting a lot of artifacting on the screen with my old ati 9800 so i swapped it out with my 6800 gt oc. When I changed the video cards i had a BUNCH of problems with drivers. I USED a driver cleaner to remove all of the ATI junk got the newest nvidia drivers running in it. Set it up for the TV and was on my way. I tried to bring up media center and it blue screens but the computer is still running and i can hear media center starting up in the back of the blue screen. I hit power and put the computer to sleep and i bring it back up and then media center is running fine. So that was like a week ago it has been limping along doing that. Now a new problem

Now when I get the tv to work the video is very laggy the sound is fine. In task manager the media center process is bouncing from 60% to 100% of course it hits 100% goes laggy. I can't play recorded TV it has the same problem but when i play a DVD it is fine.

I have checked over the hardware a bunch of times and ran tests on everything its fine. I ran an ad-aware scan last night along with avast anti-virus scan on it.

Thanks in advance.any suggestions? I think i am going to just wipe it and RELOAD it but if anyone has anything crazy to try before i do it....what driver cleaner thers a certain one that is a infectionI don't remember to be HONEST but i did the virus scan and spyware scan after in had it installed and it was ok. So i am assuming that it's not the one that i have. This weekend i am going to a giant car show up in the twin cities but when i get back I will just wipe and reload it. I considered trying to remove media center and just reinstalling that because that is where the problem is coming from has anyone tried that?You'll probably get to install Vista again also.
