My PC crashes when i play games (random)

last week i burned my old motherboard because i was an idiot when installing it in a new chasis.
I reinstalled windows and everything seemed ok at first untill i suddenly got a blue screen saying

“IRQ_NOT LESS_THAN_EQUAL”
etc etc
stop cmuda.sys (some address ranges)

now i already tried disabling the onboard sound card, but its not always it says stop cmuda.sys sometimes its just stop with the addresses.
this is the ram info i get with cpu-z

i have tried to change the ram with some from a friend, which where the exactly the same as the ones im using. It took a little longer then usual to get the error but eventually it happend

I have run the memtest86+ a little but didn’t get any errors.

any ideas, cause im totally lost some encouraged me to change my timings on my ram but i have no experience with that

before i forget this is the motherboard im using now
ASRock → Products → K7NF2-RAID

hope this is the right section :slight_smile:

I’m not familiar with this problem, but I am familiar with overclocking and stuff, so if you got a recommendation to adjust your ram timing, I suggest you go into your BIOS and fiddle with the latencies (increasing them or decreasing them until your system is stable).

Just remember: make small adjustments (5-10 MHz changes at a time), and make sure to write down the values you’ve entered before testing them. If your system crashes, just go back into the BIOS and enter the old values.

the CAS#Latency to 3 or something like that right now its 2.5

ok, changed the CAS#Latency to 3 it was on auto(2.5)

Hi, i have found out what my problem was, by running some stress tests, apparently my computer got really unstable at 2.2 Ghz so i down clocked it a bit to 1.8 and now its running smoothly
