Ummmmmmmmm..... HELP

I've have been trying to host a game and every time I do I get this error in about a matter of 10 mintues.

A problem has been detected and Windows has been shut down to prevent damage.

Driver_IRQ_NOT_Less_or_Equal

*** stop: 0x000000D1, 0x00000008, 0x00000002, 0x0000000, 0x00000008

Begging dump of physical memory.

The game just came out of beta, no one else seems to be having this issue with the game. I had Windows 2000, I was planing on buying Xp anyway and I did. I was hopeing that would fix it but no go on that. People say they can join my room and see my ping but yet in the roster I'm not in the game. I think it happens when someone tries to join. I had to turn off automatic restart to see the error if not it will just restart the pc. Any advice is greatly appreciated.

Are you sure the statement was not: IRQ(L)_Not_Less_Or_Equal ? If so,have a look at this google hit:

Are you by any chance overclocking? If so,this type of error can occur if your drivers cannot keep up with the send/recieve from the fsb...

I thought about me overclocking to. I set everything back to HW default and still did it. It could of had a L next it. It says begging dump of physical memory. Maybe faulty ram? I'll try later to set everything to HW default to see if it does it but I am pretty sure it still does.
