Updated Intel SATA AHCI controller driver, very slow and crashes
Hello.
I was/am trying to solve a BSOD issue and made things worse.
After running memory tests, hard drive diagnostics, sfc /scannow, and not coming up with anything I started to lean towards driver issues.
I used WhoCrashed to analyze my system and it pointed to iastor.sys (intel storage manager driver)
Then I used DriverMax to show me drivers that need to be updated, there were a lot but I started with 2 Intel drivers:
Intel ICH10R SATA AHCI controller
Intel 82801 PCI Bridge -244e
I used DriverMax to download and install the drivers, after updating and restarting my machine it was very slow and it crashes frequently. Takes 5 minutes to boot windows and 30 seconds or more to complete any simple task (clicking on start button, scrolling navigation sliders, opening programs, etc.) and the computer crashes before I can do anything besides open a program. It did have a message that said driver failed to install. I opened DriverMax to rollback the drivers but it crashes while doing so.
I can start it in safemode and the computer is still extremely slow but does not crash. I went to do a system restore to the point before I updated the driver and 7 or 8 hours later is was still on the logging out of windows screen. I restarted and tried again to an even earlier point and the same thing happened again. I then restarted and opened safe mode w/command prompt and ran sfc /scannow and here it is 12 hours later with only 14% of the verification phase done. It's not frozen just moving very slow.
So what are my options here? Is there any other way roll back the driver or do a system restore that I am missing? I suspect it shouldn't take this long to run these tests as I've run them in the past when everything was working properly, but is it possible that system restore was actually running for 7-8 hours and I should have just let it keep going? should I let sfc /scannow keep going? at this rate it will take days.
Is there anything else I can do?
Any suggestion would be much appreciated.
Thank you
