Hi folks...I'm out of ideas, so I hope someone here has one, and I apologize if this has been answered before -- I couldn't find anything in search, but I may have missed it. So anyway, here's the story:
About 6 months ago I wiped Vista from my system and installed XP instead. Took a while to hunt down all the drivers, but I finally got everything working more or less the way I want it. Then, about 2 months ago, I started experiencing extreme slowdowns while running multiple applications -- I installed RMClock and found that my CPUs were topping out at about 95 degrees C, so it seemed like a simple case of thermal throttling. I emailed Dell, and they sent out a repair guy to replace my mainboard & cpu.
That was about a month ago...recently, I've started experiencing the same extreme slowdowns, but it's not an overheating issue -- the CPU temp never goes above 60 degrees (and is usually in the 50 degree range). Nonetheless, when running multiple applications, the CPU cores downclock like crazy...core 0 usually runs at I believe 784 MHz, but I've seen it go as low as 380-something. Core 1 runs as low as around 200 MHz. I've tried disabling and re-enabling every power management switch I can think of, messed with OS power management, etc. I'm guessing it's an issue with XP, but I really don't want to have to go back to Vista.
Any ideas what it could be? Any suggestions to try? I'm open to anything.

). I didn't check out BIOS or chipset drivers -- since the motherboard's only a month old I figured they were up to date, but that's definitely worth looking at.
