New PC keeps crashing and giving blue screen

Hello!

I recently built a new Gaming PC and im frequently having blue screen and the system crashes.

The windows XP pro PC crashes almost twice a day, and there is no special scenario to make so that it crashes. the PC crashed while playing games, browsing the internet, or chating...

The PC specs:
CPU:
Intel Core 2 Quad Q9450
http://www.newegg.com/Product/Prod [...] 6819115042

VGA:
Asus Nvidia GTX 260
http://www.newegg.com/Product/Prod [...] 6814121262

Hard Drive:
Seagate Barracuda 7200.11 500GB SATA 3.0Gb/s 32MB Cash
http://www.newegg.com/Product/Prod [...] 6822148288

RAM: 53.99$
OCZ SLI-Ready Edition 4GB (2 x 2GB) DDR2 800
http://www.newegg.com/Product/Prod [...] 6820227269

Power Supply:
OCZ GameXStream OCZ600GXSSLI 600W ATX12V
http://www.newegg.com/Product/Prod [...] 6817341001

So what will happen is that the pc will give ma blue screen and then i have to restart it.
The most frequaent error that i get is: a blue screen saying tcpip.sys and DRIVER_IRQL_NOT_LESS_OR_EQUAL
If i check the error logs by right cliking on my computer --> manage -->Event viewer --> Applications i can see error:
1- LoadPerf EventID 3011
Unloading the performance counter strings for service WmiApRpl (WmiApRpl) failed. The Error code is the first DWORD in Data section.

2- LoadPerf EventID 3012
The performance strings in the Performance registry value is corrupted when process Performance extension counter provider. BaseIndex value from Performance registry is the first DWORD in Data section, LastCounter value is the second DWORD in Data section, and LastHelp value is the third DWORD in Data section.


on some occasions i also got a blue screen with error SCSIPORT.sys and i got once error nv4_disp.dll

I tried installing sp3 and this didnt help. i tired updating my graphic card for the latest driver and this didnt help (actually after updating the driver i was running crysis GPU benchmark and the PC crashed and gave blue screen with error nv4_disp.dll and since then i didnt see this error again)

So any ideas?

Thanks you for your help

I have a similar build, just put it together and am having the same problem.

What build is your latest XP PRO build no?

I confirm that EPU-6 engine is causing problems mentioned here. While I had turned on this aplication on AUTO mode I met plenty of blue screens. If I run on TURBO MODE or HIGH PERFORMANCE I had BS only from time to time (one a week). I think its not a good way for power managment. Best soultion is uninstallation.

I already have the latest version from the asus website but the problems still occur. I'll try to write them. Do you run on auto mode all the time?
