Bug Report Spikey FPS drops, as well as heavy bass sound

Hello there; firstly, thanks for making OBS, it's a great program.

I've been using OBS for about 1-2 months now to stream Dota 2. I have been able to stream at maxed graphics settings without any problems. However in the last 2 weeks or so I've been experiencing sporadic FPS drops. Most of the time I'll have 60-70 fps, but every 5-10 seconds I'll experience a drop to 5-10 fps for about 1-2 seconds, which is extremely annoying. I have tried running Dota2 on minimum settings, reducing the quality, experimenting with different capture methods but none to any avail. None of this happens when I am not streaming.

On a separate note, I have also noticed that my stream tends to have a bass rumble going on throughout. I do not know the cause of this. This isn't as big a nuisance as the first problem, but it would be nice if anyone could help me get rid of it.

http://www.twitch.tv/firebolt145/b/350223627: this video showcases both of these problems. You can see two separate FPS drops in the first 40 seconds of the video (at 7 seconds, 17 seconds and 35 seconds; there is an FPS counter in the top right), and hear the bass rumble throughout. For some reason my usual FPS was lower than usual as well at ~50 instead of ~60-70, but a reboot of my computer fixed that.

I currently run Windows 8. I have an Alienware laptop with a i7-2670QM CPU @ 2.20GHz (9 CPUs), 6GB RAM, and an AMD Radeon HD 6990M.

If there is any other information I can provide, please let me know.

Sure. I'm not 100% sure which one it is, so here are all 3 logs for today! ^_^

Thanks.

I see you are using monitor capture (which in the case of win8 the screen capture(monitor) code is a little bit particular, iirc)
Please drop by in our irc channel (you can use the live chat; the link is at the top right side of this page or #obsproject irc.quakenet.org if you are using a standalone irc client)
R1ch or Jim are the guys you may want to have a look at your problem.

After some tests, me and firebolt145 found that his system (cpu/gpu) was running at quite high temperatures while at full load (90 degrees celsius +++).
The sound issue remains, tho I got the same behavior while using teamviewer.

Just want to report that today the technician came in, cleaned out some dust from inside the laptop (which he reported wasn't that much actually), and then replaced both the CPU and the GPU heat sinks. He described them as 'looking fried'. After that I've been streaming for the last 5-6 hours with absolutely 0 problems.

Firstly I'd like to thanks HomeWorld for spending a couple hours with me to isolate the problem and suggest to me that the problem was overheating. And also Jim for developing such a great program in the first place.

^_^
