Reason for Memory Corruption???

[Matthias Straka]

Hi!

I have a problem with my XP Prof SP2 crashing again and again. Every time
I analyze the kernel dump it seems like it is crashing inside the function
"nt!MmUnmapViewInSystemCache"

The two bluescreens I get are:

0x0000001a (0x00000781, 0xc037dc40, 0x00000000, 0xe3993b10)
- memory_corruption
- The PTEs mapping the argument system cache view have been corrupted
- at 0x1a_781_nt!MmUnmapViewInSystemCache+3e2

0x0000000a (0xffbe0000, 0x00000002, 0x00000000, 0x804f67c8)
- IRQL_NOT_LESS_OR_EQUAL
- at nt!MmUnmapViewInSystemCache+322
- The second processor seems to allways be somewhere in the same method:
nt!MmUnmapViewInSystemCache+0x187 waiting for a spinlock

How do I track down the driver/program that caused the problem?

Another fact: The BSOD 0x0000001A happens mostly after resuming from
hypernation and logging on as a different user as the one allready logged
on.

I did check for RAM Errors (memtest + microsoft tool) several times but
had no error so far, can I be sure that it's not a bad RAM problem?

System Confuiguration:
Intel P4 HT 3.2 GHz 800MHz FSB
512 MB RAM
Win XP Pro SP2
SB Live Value
GeForce FX 5200
