IRQL not less or equal,Win32k.sys, and some more BSOD's with no names

In the last days i have Win7, it crushed few times, always during one game i play (gunz),
this is the Discriptions i get in BSOD's :

Driver IRQL less or not equal(several times) ,Win32k.sys(one time) and dxgmms1( one time)

There are 2 keyboards i use, wireless-usb, and PS2 keyboard ( im using during the game).

When i used Windows xp I had BSODs all the time,( also when i didn't played any game)
Here are some of them:

Driver IRQL NOT LESS OR EUQAL ( +portclc.sys, +nltdi.sys,+NDIS.sys,)
Internal_power_error
Bad Pool Caller
Page failt in nonpaged area
nv4 disp.dll ( nvdia driver i guess)
RTKHDAUD.SYS(related to audio driver - realtek i guess.)
YK51X86.SYS
WIN32K.SYS
KS.SYS

Windows 7 32bit Installed in the end of november.

TIA

BSOD Posting Instructions

https://www.sevenforums.com/crashes-debugging/96879-blue-screen-death-bsod-posting-instructions.html

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.

- do you always have both keyboards attached at the same time when the error occurs?
- what is the model # of the wireless keyboard
- you list your video card as 7900 gs extreme, but the driver is listed as geforce 9400 gt. please make sure you have the correct video driver installed

I never unplug any keyboard, so yes.
Wireless keyboard model: EX 100
About the graphic card, I have no idea why it listed as 9400gt, under "device manager" it listed as 7900gs,
I checked my downloaded drivers folder, and iv got the right driver : 260.99_desktop_win7_winvista_32bit_english_whql,





ill uninstall via safe mode, and redownload the last driver from nvidia, just to be sure..


Can you tell under which category it says 9400gt model?

I dont know what it says i dont have anti-virus, because im using Avira anti virus and see that the "Action center" recognize it:




very much.

- try running without the usb keyboard. just to test. does it crash?
- what version bios do you have?
- is your mobo GA-965P-DS3 rev 1.0, 2.0 or 3.3?
- is your system OC'd? If yes, revert back to normal for testing.
- run memtest86+. Allow at least 6 passes

-I ll do it and update
-bios version - F14B 31/07/2008
-Mobo rev- 3.3
-Untill now it was oc'd, but i just reverted it back
- I will mem test, and update asap

BTW, you still sure about the 9800GT detection? i couldn't find it anywhere..

Thank you!!
