Games work great, then not...

[SpaceFalcon2001]

Here's my problem (which I didn't notice in any threads that I saw):
I've already set everything according to the speed guides I could find (meaning the one on this site as well as High Priority in the Task Manager), did some of my own experimentation, and I have this strange problem with games. I have Paper Mario and the Thousand Year door, and when I play the game, it works great for about 1-2 minutes. Perfect frame rates and everything. After that time, it will slow to a crawl (10-30% speed, 10ish FPS). This isn't just because of the menu vrs the game, if I load a save state instantly it runs very well in game where it was slow before. If I pause and wait a while it will return to normal speed for bit, but then return to being very slow. It will always be very fast from the initial load, so I'm wondering if there's anyone who knows about this kind of issue that can assist. I also have Luigi's mansion which works somewhat similarly.

Tldr: My games run great for ~2 minutes, then slow to a crawl. Pausing helps.

Ok so mandatory specs:
I am using the latest stable release, Dolphin 2.0 for x64 systems.
HP dv4-1222nr
Relevant:
Vista x64
AMD Turion X2 RM-72 2.10 GHz
4gb ram,
ATI Radeon HD 3200 Graphics RS780M (Def able to play modern games like SC2)

maybe the cpu is getting too hot? causing it to throtlle down.
dont cover the airflow holes on your laptop.

plug your laptop into the power-outlet.

use a newer version of dolphin x64.

dolphin-emu.org for download.

Having had some trouble with this in the past, I'm careful about the heat thing. I keep my laptop on a bookstand I have which allows me to keep it in my lap and still have airflow (I wanna smack the "Genius" who put the intake fan on the bottom of laptops).

According to SpeedFan, My Laptop seems to be running somewhere between 80-100 C during these kinds of games. I'm not entirely certain that reading is accurate as the laptop automatically shuts down when it's over 90c (or that's what it tells me after such a shut down), but that's the temp it reports to me. Is there a place I can check if the CPU is being throttled down at those points?

It's plugged in most of the time.

use a newer version of dolphin x64.

You mean one of the SVN Builds? I haven't tried it yet, but I'm not sure if it would help.

From my experience, it could be something as unrelated as having Firefox open lol! For some odd reason, when I leave Firefox on loading stuff for a few hours, the memory usage gets so high! I only have 2 Gigs of RAM (half of yours I believe), but still, Firefox manages to use up to around 1.3 Gigs when I check the windows task bar!

I hope the new Firefox update fixed this...

Oh yeah, sometimes it's another one of those malware stuff causing the slowdown. One time there was really nothing in the windows task bar that was supposed to be causing my game to slow down so much, so I decided to do a full scan of my system. Behold! Malwarebytes (the thing I use) was able to find a couple of ugly trojans and vundo crap! After getting rid of them, my games were back to playing at normal speeds.

Anyway good luck

you can run the tool cpu-z to see the actual state and speed of your cpu while it is running a game. http://filepony.de/download-cpuz/get-mirror-server.html
