Ok, so ever since I put this machine together I have been getting the sysdata.xml error report with random restarts. I have literally been working on this problem all day now. Lately it has not been happening as much, but i d/l the battlefield 2 demo, and the second I join an online game my computer restarts. Most of the time I dont get the blue screen of death, but after reading some forums I checked the drivers through some run command to force the BSOD to get some minidumps. I know its not the ram (thanks to memtest86), and its not overheating (41c). At first it kept happening with a certain windows update, then sometimes my Tivo transfers would do it.
Anyways, here are the reports below. The first report was when I forced the BWOD, the second is when I played battlefield. They contain two seperate errors, one seems to be a driver problem (perhaps my Geforce 6600 gt, although I reinstalled clean drivers on it with no luck) or a mobo/cpu problem. Thanks for your help.

FIRST DUMP FOR FORCED BSOD

IRQL_NOT_LESS_OR_EQUAL (a)
An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high. This is usually
caused by drivers using improper addresses.

VAL - MCi_STATUS register is valid
Indicates that the information contained within the IA32_MCi_STATUS
register is valid. When this flag is set, the processor follows the
rules given for the OVER flag in the IA32_MCi_STATUS register when
overwriting previously valid entries. The processor sets the VAL
flag and software is responsible for clearing it.

UC - Error Uncorrected
Indicates that the processor did not or was not able to correct the
error condition. When clear, this flag indicates that the processor
was able to correct the error condition.

EN - Error Enabled
Indicates that the error was enabled by the associated EEj bit of the
IA32_MCi_CTL register.

PCC - Processor Context Corrupt
Indicates that the state of the processor might have been corrupted
by the error condition detected and that reliable restarting of the
processor may not be possible.
