BSOD at random times(it seems) - ntoskrnl.exe commonly referenced

[efield6568]

First of all, thanks for taking the time to help me out with this issue. It has been a long ongoing issue, that I have only recently begun to repair. Initially my system had an ASUS M4A89TD Pro mobo, 4GB OCZ Black Edition RAM, and a Sapphire Radeon HD 5770 GPU. I have since replaced the mobo with a Biostar TA970, the RAM has been replaced with 8GB Mushkin Enhanced Blackline DDR3 1600 RAM, and the GPU with an EVGA GTX 660. The BSODs do not appear to happen as often anymore, but it usually happens 3-6 times daily. Usually while gaming, when loading levels or something similar(not during gameplay), or when opening a webpage with a video, but not always.

I have attached the BSOD crash zip file, please let me know what other information or steps I need to take. Thanks again.

Update - After trying to update some drivers, the computer reboots, recommending to run Startup Repair. If I skip start up repair the PC BSODs after showing loading windows. I launched the Startup Repair and let it do the automatic fix. Rebooted, same deal. Launched Startup Repair again, went into advanced and opened command prompt and am running chkdsk /r /f (second time this week). Chkdsk is currently still running, but this makes me think I should probably replace my hard drive...

Thoughts?
