Help, BSOD crash restart

Hey,
I'm having a problem with my computer. I've never had problems with it until this morning. When I first turned on my pc this morning I got a error report message. I can't remember what it said, but it had something to do with IE7. As soon as I hit don't send, it restarted on it's own.
I then started the pc back up and I couldn't be on more than 2 minutes and sometimes it wouldn't even make it to the Windows Xp welcome screen before it restarted.

So, then I just got tired of it and just reinstalled Windows XP home. I had hoped it would fix it, but it didn't. Now I noticed that I've been getting a blue screen just before it crashes. I set it to where it lets me read it before and restarts and this is what it says.

PAGE_FAULT_IN_NONPAGED_AREA

STOP: 0X00000050 (0XD0D7FDEE, 0X00000008, 0XD0D7FDEE, 0X0000000)

That's the most important things I should be looking at I guess.
I know my system isn't overheating cause I checked my temps. My cpu is 50C and my system is 31C. I don't know what I should do. I've never encountered this kind of problem before.
My specs are:
AMD Phenom 9600 2.3ghz(not patched), Gigabyte 790FX DS5 mobo, 2xSapphire 3870 cf, 2gb ram 1066
If you need anymore info I will provide.

If anyone can help me out I would really appreciate it.

I just got a new blue screen. This one said:

IRQL_NOT_LESS_OR_EQUAL

STOP: 0000000A (0X00D6A458, 0X0000001C, 0X0000001, 0X805021B4)

I don't know what these mean. Can anyone clarify?

So, it could be my ram? How would I fix that? Buy new ram?

Could possibly be another thig associated with your RAM. Check what you have it set to in BIOS. When I set mine to 1066 for some reason it would cause my PC to just restart. No BSoD just restart. It was unstable.

Other than that your ram might just be bad.
