Built this computer less than 6 months ago. Has played all games maxed very easily. Recently, in all games including older games, I've been getting 1-2 second video delays.

A specific example:
I was playing Madden 2005 (very basic system reqs) flawlessly with everything at max. Now, whenever it goes from the play selection screen to the football field view, the players movements are very slow and chopy.

More generally, I'm seeing intermittent lag like this in all games in more random spots. It's annoying.

Other info:
Anti-virus and spyware programs were clean. I de-fragged. I am playing the older games in compatibility mode. Everything worked seemlessly for 6 months or so prior. System temps ~35C, CPU temps similar at load. No unnecessary background programs are running. Just Windows stuff and ATI stuff from the GPU itself.


Anyone have any suggestions or questions that could help narrow down the culprit? Thanks!

If the system had been perfroming well & suddenly began to lag, I doubt drivers have anything to do with it. If you're reasonably sure your CPU & GPU aren't running hot, I would look for something running in the background that you may have overlooked. You didn't mention which anti-v or anti-spy programs you're using, but the commercial products (Norton & McAfee) should be avoided as they are huge resource hogs. And opinions vary as to what are "necessary" background programs.

Hmmm, well thank you both for your relatively quick replies.

Kuwese: The old drivers were working fine for months, but I gave it a shot anyways. Maybe one of the old driver files got messed up.

Jam: I'm using AVG and SpyBot as my primary scanning programs. What I mean by nothing "unnecessary" is that the same types of programs that were running when the games worked properly are the programs that are running now. Basically nothing hardware or software related changed... just game performance.

By the way, since you mention GPU temp, could you recommend a program to monitor this? My hardware monitor only does an overall system temp, CPU temp, and some voltages that I know nothing about :P


I thought the driver update helped because it appeared to help in the first game I tried, but then I tried an FPS game with some bots offline and the lag was still very much there.

GPU-Z is reporting 38C GPU temps in game. I don't seem to be having any other problems outside of games. I also took out my graphics card and blew a good bit of dust out of it, but that doesn't appear to have done anything.

Gpu temp is fine. Do u have another system to try the graphic card? U could try to update or reinstall motherboard drivers.
