So ever since I installed my gtx 260 (I have a 400 watt psu) everything has been running badly. Not only does the framerate suck but the game will go into slow motion! I mean actual slow motion not just a choppy framerate. Also I'm having sound issues, the sound of games will also be choppy and run in slow monition when the game does. Anyone know what's going on?

Thanks.

sounds like you should post this on tested?

Well, the minimum PSU requirement for a GTX 260 is 500w, so there's your problem.

Also, did you remember to update your drivers?

400w with a system that has a GTX 260? Iz u serious?

Well, you best upgrade that PSU, dude.

Looks like the sound is still going badly and the games are still laggy. What do I do now? Reinstall windows?

@NekuSakuraba: is that after a new PSU

Yes, it is.

When my sound kept switching to slow motion and rebooting the PC almost immediately I bought a soundcard and disabled the onboard one. It helped.

I have a sound card, it's not a fantastic one but it's there. Did you also hear crackling in the sound? That is also something happening with sound. Strangely it's only when playing games and doesn't take place when listening to music or watching videos on youtube.

 
What are your other specs? 
 
Have you tried running any benchmarks?

Scratch that, it's happening in videos also. What is going on?!

What PSU did you upgrade to?

What benchmark should I run?

Are you having this issue only in game? Does this happen when you watch movies?

Are you using an AMD CPU?

Are you using Windows XP?

Do you know what your virtual memory is set to?

Reinstall your OS. That's the first thing you should consider when any weird performance problem occurs.

I have -

Q6600

3 gbs of ddr2

GTX 260

850 watt PSU (not a big brand like thermaltake or anything)

Windows 7 64 bit (if i recall correctly)

What do you mean by virtual memory?

You can try 3dmark or furmark. Also run dxdiag and check if anything looks wrong. (Run -> Dxdiag)

What do you mean check if anything looks wrong? What exactly am I looking for to be exact?

@NekuSakuraba said:

It's basically a section of your hard drive that is used as RAM. This is especially useful for people that have a small amount of physical RAM. 3GB could be close to the limit, depending on the game you are playing.

To check what Windows has set your virtual memory too, right-click on Computer > Properties. On the right side, click Change Settings. Click on the Advanced tab. Under Performance, click Settings. Click the Advanced tab. Under Virtual Memory it should show a value. Currently mine is 3965 MB. If you go into Change... it will usually be set to Automatically manage. If so, that shouldn't be your problem.

Q6600

This could be your problem. I read a forum post saying that the power saving feature that was introduced caused issues with Windows XP. That should have been fixed with Windows 7 but who knows. If you want to take a look, head here

Ok I'm running a benchmark now. Also, I couldn't find anything obvious or anything like that. Would these problems be fixed with a reinstall of windows however?

Also, why does it say my directX version is 11 if the 260 can only handle 10?

Pretty sure that's just the software version

What was your old card? Did you remove those drivers before installing these one? Re-Installing Windows should help and if the problem still continues it should rule out software issues.

EDIT: If you do choose to re-install windows, try running a movie with no drivers and see what happens, then with the drives that came with the disk and then the latest drivers from nVidia.

No, I forgot to remove the old cards drivers!

Open device manager, check that the system isn't reporting hardware issues or conflicts. (You're looking for yellow triangles with exclamation points)

Put the old gpu back in the system, see if it runs properly or if it has the same issues.

You have 3gbs of RAM, but are you using a tri-channel mobo? If you're using three RAM sticks in a dual channel machine, or one 2gb and one 1gb RAM stick then that might be your problem.

Have you tried running a game at the lowest settings and resolution and then increasing the settings incrementally to find the point at which performance goes to hell? That might be useful information.

Would the RAM be my problem if before installing the new GPU the computer was running fine?

When on the internet my computer is running really badly and it keeps freezing. I hope this information help a bit.

as been said before. any odd problems you should re-install window to isolate whether its a hardware or software problem.  
 
if its still like that after you reload windows its GOT to be a hardware problem. 

Give your PC a re-install I say.

I just re-installed windows and I'm waiting for the games to download now to see how they run. I must say though, it seems to be running a lot smoother.

Still running badly, re-install windows again? =/

Try reinstalling audio drivers

Three gigs of ram is odd... How did you get 3 gigs of ram on your system?

2x1 gig modules + 2x 512?

3 1 gig modules?

Remove your ram and try a pair of matching size modules.
