BSOD soon after start-up

Hello,

For about two weeks I've sometimes been having a BSOD within five after startup (always, otherwise I won't get a BSOD until I restart):

"DRIVER_IRQL_NOT_LESS_OR_EQUAL (iaStorA.sys)"

I've been posting on Techforums here:

And thought I might as well post here as well for other opinions while I test the drivers.

Thank you for your time

Wrench97 is very good with computer problems. Follow his advice.
I see that Avast seems to be causing problems for you when running Driver Verifier.

Uninstall Avast and use Windows Defender/Windows Firewall for testing. See if that stops the BSOD's.
