Hi, this is my first time posting here...and I'm really stumped as to what the problem is...I have been playing starcraft 2 since the release date which was over a year ago....and I haven't had any problems...but recently while I am playing the FPS drops literally to 0 from 40-50 fps and then pops back up and then drops again...I have no idea what is wrong....I have searched over and over on forums and whatnot...but no one seems to know what the problem is....I replaced my old graphics card lately with a Radeon HD 6950 and also i bought some new G Skill ram specifically my system is :
Windows Xp Service pack 3
Pentium(R) Dual-Core CPU E5400 @2.70 GHz
G.SKILL F2-6400PC2-6400 4GB 2X2GB DDR2-800 Ram
Radeon HD 6950 Graphics Card

I have also checked my temperatures

It seems to me everything is quite normal...

I've also installed the new drivers to my graphics card, direct X 11 recently...and Avast Antivirus...I've ran ad aware, spybot, and Avast and eliminated all the spyware/ viruses....I've actually also tried Formatting my computer but to no avail...Is there something wrong with my system? I really need help.....please and thanks in advance=]

Any help will be greatly appreciated!!!!

Oh yea...Although I don't think this would be the problem...I thought it might be useful the requires for starcraft 2:

I'm pretty sure that CPU of yours is bottlenecking that GPU, so that may explain the stuttering issue.
Also, Starcraft 2 is pretty CPU dependent, so that's a reason for the sudden drop in FPS.
The temps look okay.

Does any other game show the same problem?

ALSO: You can't get DX11 unless you're running Windows Vista/7.

agreed, probably your cpu is bottlenecking the GPU.

Change windows for vista/seven, because you are not even using all the 4gb of memory you have and you don't have dx 11 with xp...

what is your PSU rated for? when you upgraded your GPU did you check that your PSU meets the requirements?

Also, your mobo seems to be logging some CPUTIN at 116C max, I'm not sure what that is (maybe lifetime total) but that's pretty darn high...

if you still have your old card put it back in and run yer game, your likley to find that its smooth... as others have said its likely your new gfx card is the problem and is overwhelming your cpu... you could try putting win7 on and running the game maxed out but thats like putting a plaster on a gaping wound...
your fps may recover for this game but its likely you will still suffer fps droops.
the chances are your gonna have to get a quad to get enough bandwidth to cope with such a high end card.

so like i say try your old card if you can...
