Random BSODs, While Idle/Gaming/Watching Videos

I have been getting many different stop codes for all of these crashes, and only can recall two at the moment. 'IQRL_NOT_LESS_OR_EQUAL' seems to be a common one, and others have been caused by win32k.sys or usbstor.sys.

Attached are my dump files.

Windows 7 Professional x64
Fresh install about a year ago
Full retail (not sure, was free through student MSDN account)

Hardware: All original back to July 2007, except PSU and GPU (about 2 years old)
RAM was also upgraded a few years back.


The system is getting older, and I am planning on building a new one once I start my new job, but for now I would like to get this one working again. I am going to run MemTest next...

Thanks for the help!

BlueScreenView shows the that the problem seems to be coming from ntoskrnl.exe.

I have attached the screenshot and html report file created from BSV. The memory is an obvious problem, but these crash reports make me think there is something else wrong as well.

Any suggestions?

Anyone?

Your HP may suffer from the "bulging cap" syndrome. Open the case and examine the electrolytic capacitors. If you see them bulging from the top or sides, you have found your problem. They will cause you no end of nightmares. IMHO, get a new mobo, don't even bother to replace them. You will save much heart-ache.
