Solved Various BSOD errors occurring seemingly randomly. Custom build.

[Pauru]

My OS is Windows 7 Professional x64

These seem to happen erratically, at apparently random times, regardless of how heavily my system resources are being used. I've gone weeks without any errors, and I've faced several errors on the same day, even under the same computer usage patterns. I haven't been able to attribute these BSODs to any specific task; some happened while browsing the web, others while gaming, others still while leaving the machine idle. I'm inclined to believe that these errors are caused by hardware, since I've faced similar problems before reformatting my machine.

Majority of these BSODs are IRQL_NOT_LESS_OR_EQUAL, code 0x0000000a, but I've had other error codes under similarly random circumstances.

Attached is the folder of all diagnostic files grabbed via SF Diagnostic Tool.

Thank you in advance.

The only thing I can recommend at the moment is to test your RAM, but longer term I'll recommend installing a genuine Windows 7 -- an HP OEM installation on a retail motherboard is counterfeit. BSOD's on these sorts of installations are very difficult to diagnose and many BSOD analysts won't attempt them.

Thanks for the help. I just have two quick questions.

1. I've tested my RAM several times with memtest86, most recently last night. It ran for about 16 hours, and got 9 passes, error free. Is it safe to assume that RAM isn't the issue, or would I need to run other tests?

2. Is it possible to change the product key of my Windows 7 installation with a legitimate one, or would that require a clean install?

Yes, its almost certain the RAM is not the issue.

2. Is it possible to change the product key of my Windows 7 installation with a legitimate one, or would that require a clean install?

Yes, you can do that if the product key is also for Windows 7 Professional. However, since the current installation may have 'tampered' files, you might still experience problems even though the installation validates as genuine with the new product key. In addition, we cannot rule out the possibility that the tampered installation may contain malware payloads capable of all sorts of other "effects" (this has been known to occur). For this reason, we always recommend a clean install, as its the only way of being 100% confident you are starting from a clean slate.

If you still experience BSOD's with a clean genuine installation, we will be happy to help
