My system has been running without any major problems for long time and now suddenly i started getting bsods and complete freezes couple times per hour.
When this started i didnt install anything new on my system or change any important things.
Bsod/freeze occurs more likely if i use many programs.
I tried updating all my drivers, removed all non important drivers and restoring system.

My minidumps was too large to be attached so ill just paste my debug here:

1.

SYSTEM_THREAD_EXCEPTION_NOT_HANDLED_M (1000007e)
This is a very common bugcheck. Usually the exception address pinpoints
the driver/function that caused the problem. Always note this address
as well as the link date of the driver/image that contains this address.
Some common problems are exception code 0x80000003. This means a hard
coded breakpoint or assertion was hit, but this system was booted
/NODEBUG. This is not supposed to happen as developers should never have
hardcoded breakpoints in retail code, but ...
If this happens, make sure a debugger gets connected, and the
system is booted /DEBUG. This will let us see why this breakpoint is
happening.
Arguments:
Arg1: ffffffffc000001d, The exception code that was not handled
Arg2: fffff80001cbb107, The address that the exception occurred at
Arg3: fffffa60071209c8, Exception Record Address
Arg4: fffffa60071203a0, Context Record Address

As for your minidumps beoing too large you can Zip up to 5 together in one Zip file. Zip will condense.

Memory looks fine

hi Darknesh

Update your hardware drivers ... that error is usually caused by driver issues. Install one at a time so you can see which one was the problem child.

Spyder_1386

Looks like that reinstalling nod32 antivirus solved problem. Thanks for your tips.
