BSOD referencing iaStor.sys. Running Win 7, 64-bit.

If you would, please follow this and post it here Disk Management - Post a Screen Capture Image

OK, the reason I asked for the Disk Management is because of the Rapid Start enabled you told me about in BIOS. As far as I can determine, you are not set up for Rapid Start. However from everything I can find, your notebook is in Raid mode and there is no way to change it.

Now, none of this provides a solution to your current problem, and I am not convinced it is an iaStor issue. If you have a problem with the NTFS file system or a hard drive problem or even a driver problem that affects the read/write performance of your drive, the Sata controller (iaStor) will be blamed. Somewhere in your one time boot options or in your BIOS there should be an option to boot into the HP Diagnostic options. I would try that and see if it can shed any light on what your problem is. What brand of hard drive do you have installed?

Yes, it's a Western Digital 750GB hard drive, which I'm sure you could tell. But, the diagnostic tests for the Western digital drives as well as a modified Acronis true image imaging software can be found here WD Support / Downloads / SATA & SAS / WD Black If you could run the Data Lifeguard for DOS, it could tell us if it is the hard drive. The other version is an installed version where you install it. Either version is OK, but the DOS version is better as the hard drive is not in use. You boot into the media instead of Windows, which means the drive is not in use by Windows, so the test can be more accurate. Please run the short test and the long test.

Did you follow the tutorial Koolkat posted about running a clean boot in posy #2? If not, please do so. Also, please back up all of your personal files to another hard drive, preferably external.

Avast uninstall utility avast! Uninstall Utility | Download aswClear for avast! Removal The main reason MSE is highly recommended here is there is no case I know of that MSE has caused a BSOD. It is also very light on resources. I use it and Malwarebytes. They both seem to work well together. I'm not ready to recommend a reinstall yet. It may come to that, but I may recommend a couple of things that can end up making you have to do one. A windows 7 ISO file can be downloaded, but I thought HP gave you the option of creating installation DVDs from their recovery partition. I may be wrong, but I thought I recall that. Uninstall Avast and install MSE Microsoft Security Essentials - Microsoft Windows and try the clean boot. See if that helps. The best anti virus program there is is you knowing what web sites you are going to and knowing where you are downloading from and what you are downloading. That is true no matter what AV program you use. But, Avast is free and lets just try it without it for a while and see if we can find a solution. If not, you can always reinstall it. Just be sure to keep all of your personal files backed up. I would always recommend getting a couple of external hard drives for that purpose. All my files are on at least 3 external drives. The truth of the matter is, the question isn't if your hard drive will die, but when it will die. When I was younger, I got burned real bad when I had a drive die on me and it cost me dearly, plus I had things that could never be replaced. I swore then, it will never happen again. That's why I preach so much about it.
