Restarts and some bsod

lately my comp started to behave very strange, restarts and some bsod(rare)
i attached some dump files the most recent ones if more are needed i can upload more
usually restarts when i try to play a game after random time periods
i have a nvidia 7600gs with latest drivers installed

In all four minidumps the WinDebugger symbols could not load to give code errors. Two of the drivers cited were core Windows drivers.

Another driver was nv4_disp.dll which is a Nvidia driver.

The last driver cited is yk51x86.sys which belongs to NDIS5.1 Miniport Driver for Marvell Yukon Gigabit Ethernet Controller and/or Adapter.

Do the following:

1. Run ChkDsk in the Run box.

2. Scan for viruses, etc.

3. Run MemTest for a minimum of 7 passes.

4. Run a full harddrive diagnostics.

* One other thing, did you have these issues prior to SP3?

now that i think about it before installing sp3 i had about 2 bsod in a year
why do u ask about sp3 any particular reason i should not use it ?

i analysed all my dump files(I'm curios so i learned how to to that) and in the majority of times nvidia drivers are the guilty part only the last 4 that i posted here are related to windows core

i tested the memory is ok

nod32 didn't report any viruses
kaspersky no viruses
avira no viruses

for the hdd diagnostic i have to wait some time because i have 4hddx400gb and will take some time

thanks for responding

People are having issues with SP3 such the kind you are experiencing. Their systems were stable prior but after installing a myriad of issues have occured across a fairly broad spectrum.
