Windows 7: Self-built gaming PC having BSODs and freezes; can't pinpoint cause.

Self-built gaming PC having BSODs and freezes; can't pinpoint cause.


Over the past few months I've gotten countless BSODs and freezes ( the screen freezes on whatever was last displayed and is accompanied with a buzzing noise in my headphones which I believe is the last sound played). The blue screens and crashes occur randomly While playing games, watching YouTube/Newgrounds videos, browsing the internet, while just idling on the desktop with only Skype running, and even a few times at the Windows login screen (happened only a few times, and repeatedly selecting "start Windows normally" after it kept giving a BSOD at login, it stopped crashing and I logged in normally), none of the crashes consistently happening during a certain activity.

I've done quite a bit of troubleshooting but I'm stumped, because the error reports don't point to the same thing most of the time. I've tried downgrading my graphics drivers, and then when that didn't fix the problem updating them to the latest version. I've monitored my hardware heat output with several programs and nothing seemed above acceptable levels, whether gaming or idle. I've scanned for viruses with Norton 360 and Malwarebytes and nothing was found. I ran MemTest86 for 18+ hours with no errors found. I've tested my hard drive for errors and defects and it appears healthy in both software and hardware.

Before anyone tells me to do so, I should mention I haven't tried removing one RAM stick or using another video card, but I plan to do so in the next few days; I'm just hoping someone can give me some useful info from the crash data while I do some physical troubleshooting, and maybe someone can even throw out some educated guesses as to what may be the cause of the errors.

I posted a topic on the Windows forums previously, but I wasn't really getting much help and it seemed like the guys on that forum were just spouting highly generic troubleshooting info and not anything specific to my problem. I do realize troubleshooting a computer is a process of elimination, but the guy I talked to was like a robot reading a list of responses. Please take a look at the topic here:

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

And another forum I posted the same topic on:

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

My system specs can be found on my profile page; I filled out everything that I could.

I attached the SevenForums analyzer's report to this topic, but let me know if any additional info is required for troubleshooting. I had a lot more BSODs than just what's indicated in that folder (like "MEMORY_MANAGEMENT" crash etc.), but I accidentally deleted the dump files with CCleaner before I knew anything about dmp. files, so the ones in the folder are just the dmp. files created from the crashes I've had after a certain point (the system freezes leave no dump files and only show up under the reliability monitor as "windows was not properly shut down").

Any help is greatly appreciated!

I'll die of a stroke soon if I can't figure out the problem with my computer.

Thanks for your response, but I already did exactly what you suggested a few days ago, and I'm still getting blue screens. In fact, I got one just now, one I haven't seen before (BUGCODE_USB_DRIVER). I've attached a new SF error log for you to look at. Why am I getting so many different types of crashes? Any idea from the information of what's highly likely?

Your System Information file still points to two instances of Norton installed:

Start Menu\Programs\Norton
Start Menu\Programs\Norton 360
You may also want to follow these steps:

Scan for any missing, modified or corrupted protected Windows files with:There's seems to be a issue with some of the USB drivers, follow these steps:
  1. Start
  2. Type: Device Manager
  3. Expand USB Controllers
  4. Uninstall driver (for every listed device)
  5. Reboot
The drivers should now be automatically reconfigured by Windows upon reboot.

If you are using any USB devices, then remove these from the USB ports (leave keyboard and mouse), and then update all the devices with the latest drivers, including the mouse and keyboard if applicable.

I already tried the prompt command /SCANNOW last night, nothing found. Also, let me clarify what I meant about Norton; I meant that I previously removed the program, and used my computer without Norton installed until I got a blue screen, which I did, which means removing Norton did not fix the crashing ( I then, after proving it didn't stop the crashing, reinstalled it and am currently using it), and neither did removing the drivers and then reinstalling the latest ones (I also tried downgrading them before that, and that didn't work either).

The USB error is the first I've seen so far; can it really be a driver? I'm worried my MOBO might be shot, seeing as I've gotten so many different types of errors that seem to pertain to nearly each of my hardware components. Also, at the behest of a Microsoft community vet, I recently updated my USB drivers from ASUS's website.

Personally, are you confident it's just software and/or drivers, or does it seem like a hardware issue to you? I can use all the advice and opinions I can get, even if they're just guesses.

Since, you have had so many crashes, Norton could be one of piece of the puzzle, and in my opinion why would you pay for a program when there are free and lightweight alternatives (just a suggestion)?

What driver version are you using? Leave the driver upon the latest WHQL driver, which has tested by Microsoft for stability issues and performance problems.

What were the results of the scans? Malwarebytes? SuperAntiSpyware (in link) and MSE/Norton?

Have you attempted the USB troubleshooting steps taken for the USB specific bugcheck?

Well, in my experience, free antivirus programs offer little in the way of real-time protection or browsing/website protection, and Norton gets updated all the time, so it's vastly superior to the free alternatives in my opinion. Also, as I said, I've already pretty much ruled it out as the cause of the crashes because it was uninstalled and the computer crashed anyway. I was sure it was the problem as well until that happened.

I'd like to mention, the PC didn't start crashing until the 30th of November, 2012. Before then, nothing irregular was occurring with the machine, and even now it runs programs and games like a dream, until it inevitably crashes randomly (it used to be every 3-4 or 5 days, but lately it happens every 1-2 days.

As for my USB drivers, when I select the USB's themselves the version appears to be 6.1.7601.17586. There are some Intel drivers listed under the USB tab as well, and the version of those are I have not taken any action based on the generic troubleshooting info for the USB error as of yet.

Both Norton 360 and Malwarebytes show no sign of viruses.

Are you using the March 25th driver? I will await the results of the USB troubleshooting.

If you mean the graphics driver, yes, I'm using the 314.22 Nvidia driver, and before I installed that, I tried downgrading to an older driver. It still crashed after each instance.

I took the advice of a Microsoft community vet a while back and updated my LAN, USB and audio drivers from Asus's website, and the current version of my Intel USB 3.0 root hub driver is V Is there really any reason to reinstall the USB drivers? I mean, the crashes were happening before I updated, and they still are now after. What do you suggest I do? I'm kind of at a loss about what to do about the USB, or whether any action is even necessary.

This might help a little.
Check the EVGA site for the driver for your video card and see if it recommends the same driver Nvidia recommends.
