Hi guys.

I moved to Windows 7 recently and I seeing to have some sort of graphics issue.

First of all, my setup is E4600 2.4Ghz, 4GB DDR2, HD4870 512MB PCI-e.

I've never had a problem with this setup until now.

When I watch something in HD, the playback is just really choppy and slow, whereas on Vista playback was fine and smooth as normal.

I also installed COD MW2 yesterday and that was unplayable, it was stuck at about 9-10FPS.

I'm using the latest Win 7 drivers....

Any ideas?

Cheers

Edit - Just realised that when I'm watching HD movies on the likes, CPU usuage bounces from 95% - 100% always. Could this be the cause?
 
Uninstall and reinstall your graphics drivers and get the latest DirectX. Also get a codec pack specifically for Windows 7 (K-Lite Codec Pack)

Only other thing i can think is Speedstep playing stupid? Try disabling it in the BIOS.

Hi and thanks for your reply.

I've recently had no bios battery in my PC so I can't really change or save anything until my new one arrives. I guess it's possible that speedtest has defaulty been left on. :confused:
 
Try the former suggestion first and report back. Cant see speedstep messing it up, why are you ordering a BIOS battery online? Surely you can just pick one up over Tesco or something?
 
Got a new bios battery today and everything is back to normal. HD Movies are fine and COD MW2 is running sweet. Cheers guys.
 
Np, will note this out come. Never would have thought it would be down to the BIOS battery if im honest.

Yeah same. Only thing I can think is that because there was no battery in it was messing the BIOS settings up each time the computer booted. Strange one though.
