Ok, here's the problem. At least once a day I get a random reboot or crash. Usually it's a total restart without any warning but sometimes I get the BSOD and the message: DRIVER_IRQL_LESS_OR_EQUAL
STOP 0x000000D1 (0x00000000, 0x00000002, 0x00000000, 0x00000000)
BEGINING DUMP OF PHYSICAL MEMORY

My system specs are in my sig, so that's what I'm working with. My temps are around 40C at all times so heat isn't the problem. The power supply never wavers, so it's not that, and both sticks of ram (after lots of testing) appear to be fine. I thought it might be the RAM at first, so I tested it in my old computer which houses a Duron 850. I ran MEMTEST86+ and Prime95 for a couple hours for each setting I could think of. It ran flawlessly with the RAM at 100 and never crashed. Then I put my 2500+ in it and ran it at 100 and then 133 (this particular mobo doesn't support above 133 fsb) and it ran flawlessly as well. So now I've put everything back in my normal system. Here's what I've tried doing so far:

RUN MEMTEST86+
1) CPU and RAM at 166FSB -> Crashes within 5-30 minutes
2) CPU at 133, RAM at 166 -> Stable for at least 3 passes (stopped after that)
3) CPU at 133, RAM at 200 -> Stable for 8 hours (never crashed)

Here's the real weird thing. After running the CPU at 133 and the RAM at 200 for 8 hours without fail, I drop the RAM back to 133 to match the FSB, go into Windows, and BAM! I get the dreaded BSOD within 10 minutes. Honestly now, wtf?!? I don't have access to a spare mobo, 2500+, or more RAM without buying it. How can I tell whether it's the RAM, CPU, or motherboard now?! Please help!

Sounds like either a PSU or RAM issue and im leaning towards RAM. The problem with determining if its RAM or not is catching it when it screws up. Just because you run a test and it comes back OK doesnt mean that it is all the time. Otherwise you could be having an incompatibilty issue.
