Ok, I will try. But this Dell diagnostic is taking forever.
In the meantime, is there a way to correct the IaStor.sys error without running System Restore, or re-installing the OS? I have System Restore turned off because my OS is on an SSD, so that might not be a good option, anyway.
I have a bootable USB thumb drive factory OS install... but again, I want to avoid reinstalling the OS to correct this.
And the bigger question is, why would attempting to install RAM, that the computer rejected, cause the degraded performance?
Can an attempted install of an incompatible DIMM "break Windows" like this?
Right?!
It makes no sense. Can you advise on the iastor.sys question? Now I'm getting looping BSOD's on startup every time that program begins in startup.
Can I uninstall Intel Rapid Storage, and try to reinstall it? Or is that a bad idea?
You can try. But use the Revo uninstaller > advanced option. Take the freeware/
Download Revo Uninstaller Freeware - Free and Full Download - Uninstall software, remove programs, solve uninstall problems
I uninstalled the Intel Rapid Storage Program from Uninstall Programs (not Revo). There was no crash on startup this time, but the system performance is still completely degraded. 100% CPU usage when using any program.
