I've been getting seemingly random lag (in nearly EVERY application - even Minecraft) on my computer. Everything will be running fine, at very high FPS rates until after a short period of time, lag will begin and frame rates drop to around 5-10 FPS. After a while, it'll go away but then will come back.

I've been having this problem for quite a while yet can't find a solution or anything through Google. I'm pretty sure it isn't my graphics card, RAM, or processor.

Specs:
OS: Windows 7, 64 bit
Processor: Intel Core 2 Quad CPU Q8200 @2.33GHz
Memory: 4096MB RAM
Graphics card: nVIDIA 9800 GT (handles Crysis (1 and 2) and other video games VERY well - that also makes me think it isn't anything graphics card related)
DirectX version: DX 11


I've tried killing processor-heavy processes, yet that didn't help a bit. I've also even tried modifying my computer's power settings, but that didn't do anything either.

Help is much appreciated, thanks!

Isn't Mine Craft programmed in Java? It could be the garbage collector. Doesn't matter if you have an IBM super computer when that garbage collector kicks in. Perhaps it's to do with the world you on? Other possibilities are anti-virus, or perhaps your swap file if you have a particularly memory intensive game, or if you're playing games online, it could be as simple as internet lag.

Just a few thoughts.

The nVIDIA 9800 GT doesn't support direct x11, that could be your problem, however your games should automatically run in dx10 mode as the card supports that and not dx11.

Although a while back I was noticing something similar, I then noticed that it only occured at a certain time and then remembered that my internet security software was running a scheduled scan at that time. That could be your issue if you have something set up like that in a similar way, just play your games at a different time or set it to scan at a different time.

@Fallout it isn't necessarily a problem specifically with minecraft, it happens everywhere with every program.

@Mazz I was thinking the same thing about the anti-virus, it scans at periodic times however the lag starts (I believe) at random intervals.
And I didn't know the 9800 doesn't support DX11 However most of my games run in DX10, so that couldn't be the issue right?

Make sure to disable throttling:

Also, check your temps.

AV scans can normally clog up your proccesser. Check if there scanning when you get lag.

Edit dammit mazz beat me to it.

Make sure all your drivers are uptodate, could be a bad patch/corruption. Try a reinstall.

I recently noticed in Win7-64 I get random lockups for 30sec then everything runs fine. Maybe a recent Win7 update?

What's this talk about D3D? Minecraft uses OpenGL!

I'd bet (like a dollar tops) that it's an antivirus problem. What antivirus are you running?

I just shut off my AV completely - still got the random lag spikes. Also made sure it wasn't even scanning when it was on, so that eliminates the AV suspicion.

I also updated pretty much ALL the drivers on my computer (the graphics driver is up-to-date as well).

@Jerico, thanks I'll try that

When this happens again, open up task manager, switch to the "performance" tab, copy it, and post it here. How much RAM is being used when this happens? My bet's on the swap.

@TheComet, here it is right when it starts:




I'd really appreciate a solution - this is making it impossible to work in any development programs (UDK, DBPro, FL Studio, etc.)

when it happens, what is/are the processes with the highest cpu usage?

I have a feeling you have a couple cores maxed out.

Well I recently noticed that whenever I open an application, a few minutes after I open it the lag starts. So it's usually whatever application I opened. After opening UDK, it started to lag, and UDK was hogging up the most CPU which is actually very unusual. I tried setting UDK to run on only one of the CPU's but that didn't work.


I just defrag'ed the whole computer, so I hope that'll do something.

EDIT: That actually didn't help at all, for some reason it deleted UDK after the defrag completely -.-

Could be a harddrive issue. Both seagate and western digital have their own disk checking tools, though I believe they are destructive. I'd do it anyway because you don't want these kind of issues on a machine you'll be doing work on.

WD tools work well, Seagates are worthless. A SMART report indicated several problems on my seagate drive whereas their tools said it worked fine and thus refused my RMA. I have a 320GB paperweight.

There was a tool I used to use that would analyze every spec of RAM in your system and report any possible problems with your memory. But I can't seem to figure out what it was called.

Looking at the CPU usage on the processes tab would be more helpful to determine if something is running your system down.

Whoops, it didn't delete UDK, someone in my house accidentally uninstalled it.

Defrag didn't work, and still not finding any other solutions. Any other help?

You could try a pc tune up type thing. This is a program I run now and then and it optimizes performance, fixes registry settings etc. You can try the free version (that's what I use) to see if it will help.

Is that any good on 64 bit systems? I couldn't tell from the Mentest website.

That made me a little confused, because I only see one core on your task manager... Do you have 2 physically seperate CPUs? I also notice a lot of processes running... 93 processes? That can't be right, can it? 2.57 MB of used RAM is quite a bit don't you think?

Can you post the processes tab as well if possible?
