BSOD Problem

I'm having bsod problems on win7. I figured it out that my realtek network card is causing this and updated my driver to Win7 driver. But it's still giving me the bluescreen. How can i solve this?

Also my programs are crashing with no reason either.
It wasnt like this when i first installed Win7. Missed my XP.

Here is my latest dump analysis:

Code:

DRIVER_IRQL_NOT_LESS_OR_EQUAL (d1)
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.
If kernel debugger is available get stack backtrace.
Arguments:
Arg1: 00000014, memory referenced
Arg2: 00000002, IRQL
Arg3: 00000001, value 0 = read operation, 1 = write operation
Arg4: 8aa120a5, address which referenced memory

Here is all of my dump files. I've had more but they got deleted.

And there is also Netlimiter Ndis Driver installed. I dont know if it does matter or not.

Most techs would ask next, "Have you tried Safemode?" Blue Screens can mean alot of things...

The fact you're saying your running programs are crashing may well indicate faulty RAM (for some reason Windows 7 is very unforgiving when you get RAM errors).
I'd suggest running MEMTest. If you get errors, its your RAM.
If not, remove your network card. If it stops giving BSOD, try sticking the card into a different PCI slot. If you get BSOD after that maybe its time to get a new network card..
