Please help! Can't figure out why computer keeps crashing!

[Dem0nGam3r]

Hello, lately I've been experiencing very frequent crashes, including BSODs, "buzzing" freeze crashes (the computer would freeze on the current screen and loop the last sound infinitely and would never recover), and just now my computer simply went black and restarted for no reason. The blue screen error messages (at least the ones I can remember) were, first of all, MEMORY_MANAGEMENT, followed by IRQL_NOT_LESS_OR_EQUAL, then DRIVER_IRQL_NOT_LESS_OR_EQUAL, and then more recently I got the aforementioned "buzzing" freezes, and now this black screen and restart. I built this PC myself (I've only had it a few months, and it was working great until the last few weeks or so). Here are it's specs: MOBO: ASUS P8Z77-V LX OSS: Windows 7 Home Premium HDD: Western Digital Caviar Black 1TB CPU: Intel Core i5 3570k (3.4GHz quad-core) GPU: NVIDIA GeForce GTX 660 Ti RAM: Kingston HyperX Genesis 8GB (2x4GB) PSU: Corsair CX750 Bronze Case: CoolerMaster Storm Enforcer. I ran MemTest86+ for 18+ hours, which detected not a single error. If anyone has a general idea of what's wrong or advice/self-help tips, I would greatly appreciate some assistance; I'm at a loss and don't really know enough about computers to know what's causing these problems. Thanks for taking the time to read this!

(Edit): Also, this will probably help a lot, I copied the crash report of a couple of the blue screen errors:

A good start first reinstalling all drivers as updated as possible. Double check your bios settings for voltages and memory timings. Basically ensure that everything is as it should be. I would also get a program to monitor your voltages and temps. Are you running anything overclocked?

 

[pete123edgar]

Probably your ram, try running with one ram at a time. RAM is like your short term memory, without your short term memory, you would not be able to function day to day task just like a pc with a defected ram.

memtest 86 is the first thing to check. like above poster said just one stick at a time

No overclocked components, and I doubt the problem is voltages/memory timings; wouldn't they have been a problem from the start if they were incorrectly set up? The crashes never occured until the last few weeks. Oh, and I forgot to mention, I recently cleaned the dust out of the PC, and it was quite heavily coated in dust (mainly the fans). I know it was stupid of me to wait so long to clean it, I just hate moving it outside and opening it up. Maybe it caused some serious overheating? I doubt that because the errors, as I understand, don't point to that. And if it were overheating I think the crashes would be more abrupt?

How exactly does that help, testing one stick at a time? Is memtest more likely to detect an error with only one stick, or do you mean letting the computer run and seeing whether it crashes or not? I've seen this suggested before to troubleshoot, and honestly I don't understand how that method works. Forgive my ignorance.

This might be a silly question, but does anyone think if I took it to a repair shop, they'd for sure be able to diagnose the problem, or would they not be able to do much more than I can? It'd save me a lot of time and headache to have someone take a look at it if they could figure out what's wrong.

Sometimes its just some little things that are causing the crashes its either a bad dimm slot, bad ram , the gpu drivers or the psu. Also make sure you are running the latest memtest and installed all the latest driver.

Yes, you test one stick at a time and one slot at a time, run it and see if it crashes

Alright, I was already planning on making sure the drivers are updated (the video drivers are updated for sure, and I'm up to date on all Windows updates, but there are a ton of different system component driver versions on ASUS's website and I was having trouble knowing which ones to install, and I'm not even sure mine are out of date), and the only other thing I can try if that doesn't fix the crashes is reinstalling Windows, and then, if that still doesn't work, take it to a repair shop.

I was afraid that's what you meant. The problem is it only crashes around every 3-4 days, so I'd have to use it at half-capacity for that long.

 

[Dem0nGam3r]

Does anyone see a single most-likely cause based on the information I gave? Not to dismiss your advice, but those tips are pretty generic ( I WILL perform the suggested methods if possible). I would like to know the general severity of the issues so I have an idea of what I can expect I'll have to do in the future. Thanks for the replies, though!

make sure your asus mb has the newest bios for ram/usb/cpu code. go into the bios on the first page and read the bios rev then update it. also make sure in the bios with asus your running in standard mode. the asus performance mode changes the ram to cpu timing where your system can become unstable under loads. in ai tweeker make sure under dram timing xmp profile is on.
