Hi all,

I've been using my new build for about a month now, and I've noticed a strange and slightly annoying problem. It's a little hard to explain, so please bear with me for a minute. I also hope this is the right forum to post this.

What happens is that I get random 'jerkiness' or lag. I've noticed this in games, though more in some that others, where it manifests itself by the game freezing for about 2-3 seconds and the sound looping, before the game goes on normally. Bioshock 2 and Borderlands have been running perfectly fine without this happening at all, whereas Half-Life 2 (and, generally, all Source games) has been giving me this a lot.

It also happens when using firefox, more at some times than others (I'm guessing it's site dependent). For example, right now while I'm typing, the computer stops reacting every few minutes or so, just for a few seconds, and then everything I've typed in that time appears quickly. Finally, it happens occasionally while watching video. Youtube is particularly bad.

The CPU and memory usage are normal/low, and neither really seems to spike when this happens. CPU and GPU temperatures are all normal, and again don't really seem particularly high at times when this happens. Nothing in my computer is overclocked (other than the stock clock for the graphics card).

Really hope someone has some suggestions. Build details are in my signature.

Thanks

Rid

Just tell me how much memory you have, how much memory is free, operating system, and do you have any hard drive activity when the freezes/stutters occur?

EDIT: I see your sig now. What drivers on the 570?

I have 8GB of RAM, and about 2.5 of that is in use pretty much consistently. Obviously, it's refusing to do it right now so I can't check if there is drive activity. I'll make sure to check if it happens again (it's an SSD, so I can't hear the telltale sound of the drive working away).

The nvidia drivers are 270.61

Open msconfig and on the General tab choose "selective startup" (uncheck all three items) and reboot. Does the problem still occur? If not, start adding items back to msconfig one or two at a time, rebooting after each change, until the problem reappears and you'll have identified the offending process. This is clearly a time consuming procedure, but it is the best way to determine if some process loading with the system is the cause of your problem.

Ok, I was able to start with all services, and it seemed to run well. I was able to start firefox, have 3 youtube videos running and check facebook and a few other tabs, and it was completely fluid.

Now I've booted with all startup items, and opening new tabs seems to take a second longer, and the jerks are beginning to happen already. So clearly something there is the problem. I will start adding them in one by one.

Thanks for the tip.

Actually, nvm that. It seems to be doing it with just microsoft services and no programs set to load on boot. I don't know why it didn't do it before, it does seem very random.

However, the system drive light does seem to turn on whenever it happens, and stays on for the duration of the 'lag.' So I guess it's something to do with the SSD?

Do you mean the HD activity light? Open task manager to the Processes Tab and sort on the cpu column with highest usage at the top. Next time it happens, see if some process is spiking

Nope, nothing like that. Firefox goes to about 6% when I type, but stays there even during the stutters.

It definitely seems to be happening less often at the moment (with no boot items), but it still happens.

Well, in spite of what you said in your first post I suggest you post in the Am I Infected forum on this site and make certain.
