BSOD - crashing once or more a day

Need some expertise and guidance on how to fix the BSOD errors I keep getting. I have an HP Pavillion with 2GB Ram, 32 bit with Windows 7 Ultimate Premium. This is not the OEM OS that came with the laptop. I installed this on a new hard drive over a year ago when it crashed and have not had any issues until about a week ago. I think the issue is due to possibly a driver but not my area of expertise and really some help. I followed the BSOD instructions and have attached the files required. Any help fixing this is greatly appreciated!!

They are just about all reporting I/O failure from your hard drive. If no configuration changes (drivers, BIOS, etc.) have been made recently then why can bet most of our money on the drive itself being dead. Hopefully you are still under warranty for it. If you can, try to backup the data on your drive using a livecd environment like Parted Magic.

Hi Vir Gnarus,

Thanks for the quick response! I have not made any conguraitons changes to those items unless they update automatically somehow. I'm certainly no guru there. I don't think its under warranty still but will have to check my documentation. Would there be a way to see if any config changes were made to those types of things?

If you personally have not installed updates for them recently, then we can assume HD failure. Note that the motherboard's HD controller may also be at fault here, though more likely it's caused by a bad hard drive.
