Odd lagging issue while gaming (SOLVED)

Since I'm new here, I'm going to use mechBgon's template.

Overview of the problem

Two games so far have been having lag issues

Full description of the problem and symptoms

The lag problem is repetitive. It happens about every 10-15 minutes, and lasts about 2-3 minutes each time. The first instance I had of this was while playing WoW (I just signed up for a trail account to waste some time). Normally I see myself having around 45 or so FPS, and this lag brings it down to 4-5 FPS.

At first I thought it was a game issue, as I did try a couple of graphics options changes and at first it seemed to have worked, but it only made it take about 30 minutes before it first happened, and then it went back to its normal 10-15 minute cycle. However while playing Splinter Cell tonight I found that I was encountering the same issue while playing this game, so I changed the point of blame from WoW to my machine.

Did it work normally at one time, or has the problem always existed?

For both of these games, this issue has occurred every time I have played them.

Is the problem consistent and repeatable, or entirely random, or semi-random?

As stated prior, each time I play I encounter the issue, and the issue repeats itself regularly during play.

I already tried these steps:

I haven't tried anything with Splinter Cell, but I have tried a few things for WoW as suggested in WoW's tech support forum. Mainly this involved enabling triple buffering and I believe I turned off Transparency. This, as mentioned above, is what caused the game to run normally (in fact I got better FPS after this) for about 30 minutes before the lag issue returned (again, the issue usually happens every 10-15 minutes whether I just log in for the first time or not, and this is the only time it caused the game to take longer than that before the lag appeared). They also suggested to run this DPC Latency Checker program they mentioned, which I did for both WoW and S.C. and saw no abnormal changes in its monitoring for either one.

My software:

I'm running WinXP SP3, did not have any firewall or antivirus programs running, nor anything else intentional besides maybe a web browser (which I also closed at one point, but it didn't change the outcome).

My hardware:

This is a system I purchased a few months ago from a friend of mine.

Motherboard brand & model: MSI Amethyst-M
CPU model (and is it overclocked?): AMD Athlon 64 X2 3800+ (Socket 939) I don't believe it's overclocked. MMX(+), 3DNow!(+), SSE, SSE2, SSE3, x86-64 instructions
Video card(s) brand & model: nVidia GeForce 8400 GS (512 MB DDR2) with 190.62 drivers
RAM modules brand & model: 2048 MB DDR via 4 512MB PC3200 chips, 3 MOSEL 1 Hyundai, all four show 2.5V for voltage
Power supply brand & model: Unknown

Other information that might be relevant

Let's see... WoW plays windowed, S.C. has no windowed option. There are a couple other games I play on this machine and I haven't noticed this lag issue with them. The motherboard is SATA capable, but both HDD's are IDE. Windows on C, everything else on D. I've been pondering if it may be an issue with a possibly dying IDE cable. Can't find a BIOS update for the mobo. All help is very much appreciated, and if you need any further information to make some diagnosis please ask and I'll do what I can to get that information. Thank you!

Check for malware.
Run the manufacturer's diagnostics software on your HDD.

Are you playing Splinter Cell online? If so, are you using Wifi?

If both of these are true, make sure you use the wifi card manufacturer's wifi config utility, NOT the built-in XP one. The XP one will cause periodic lag spikes...

@aGreenAgent: Nope, no online play with Splinter Cell. I did ponder an idea related to this which I'll mention below.

Taking a cue from @oynaz, I asked around about a decent free virus checker and was referred to AVG. Got that, scanned the system, only a couple "tracking cookies" found. From then I went into BIOS and ran both SMART short and extended tests on both drives, both came back error-free. I then ran chkdsk on both drives. It found a few problems on the C drive so I did /f and that didn't bring up any more problems. (Keep in mind I keep my files on D drive, Windows only as much as possible on C). After that the issue still occurred, so I defragged both hard drives. Still experiencing the issue.

A few of things I am thinking of trying after I take a nap (feel free to add to this list please):

1) Try playing Splinter Cell with my internet connection severed (possible botnet-type thing somewhere on my computer that wasn't found by AVG?).
2) Run my Windows Memory Diagnostic CD to test the memory (I did this about a month ago with no errors, but who knows).
3) Change out the IDE cable on drive D for a different one (possible bad cable?).

Thanks for the suggestions so far. It looks like the issue wants to keep bugging me, so keep the suggestions coming if you have any! Thanks again! :)

Check your processor temps. If they're getting hot while gaming, that could cause your problem. I know it sounds unlikely, but I fixed my friend's Fallout 3 issues (similar lag spike problems) by re-doing the thermal paste on his machine.

Hmm, I do recall having heat issues earlier this year. I'll make a mental note to grab SpeedFan when I awake and see what's going on there. :thumbsup:

Stopping by to relay the temps SpeedFan found (I haven't tried the other items in my list above just yet). There are a few high ones (as marked by a flame icon next to them). One is the GPU which is reported at 97C, the other is Remote 2 at 116C (I'm not sure what this is... also Remote 1 is 41C), and one of my cores is 97C (the other steady around 44-45C). Both fans at 40%.

What are normal temperatures for these things, and what are these Remotes being reported?

Looks like @aGreenAgent nailed it - I ran SpeedFan and bumped both fans up to 100% and let my temps cool down for about 15 minutes. The GPU and that high-temp core both got down to low 70s and below (and of course Remote 2 also lowered, as well as everything else), so I hopped into WoW and played lag free for just about an hour (it didn't lag at that point, I just figured I had played long enough to understand that the problem was over). I even saw FPS in the 80s which I've never seen before! :Q

I kept SpeedFan open while playing and noticed that during play the temps would slowly creep up, getting into the mid 90s while battling, and dropping to upper 80s when just wandering around towns and such. This definitely coincides with how the game would start to lag slowly over time. My FPS would start high 40s low 50s and gradually drop to 20s and 30s, then bottom out at 4-5 FPS - no doubt the computer just saying "Enough!" and taking a break :laugh:

I suppose next I'll scour the site for some airflow techniques for my case, to see if I can combat that slowly rising temperature. Big thanks again to @aGreenAgent for the heat suggestion, turns out to have been the issue, and a big thanks to everyone else who replied with suggestions. Not only did I set out to fix the problem but also to learn as well, and both definitely happened today. I knew Anandtech would be the place to go! :thumbsup:

Glad it worked. You may want to reapply thermal paste to your processor/heatsink. It's important that this is done right (my processor gets to ~48C Max on any core), otherwise heat builds up on the die.

I've never done that before. What all would I need? Are there tutorials out there? Also, could this be why one core is always significantly hotter than the other?

It would be why all the cores are hot. I'm sure there are tutorials out there. You would need a tube of Arctic Silver (I think it's the best kind). The thermal paste is what lets heat leave the processor and go onto the heatsink. A really good test to see if this is your problem is to let your processor get that hot, then touch the heatsink. If it burns you, then you have an airflow problem. If it's only a little hot, then you need to redo the thermal paste.

So a nice warm heatsink, not too hot not too cold, is ideal? It's sounding like the Goldilocks of computer health :laugh:

no, if your processor is 90C, then you want your heatsink to be 90C. If it's colder than that, then heat isn't leaving your processor.

I guess in that sense, you do want a heatsink that isn't very hot - but only because that means your processor isn't very hot.

It's just good to know whether it's your airflow or heat transfer that's the issue. Let me know how it goes.... (and don't actually burn yourself...)
