Windows 7: BSOD random while idling or during light tasks.

13 Jul 2015   #11

Windows 7 x64 Professional

The BIOS mode is set to AHCI.

While the symbol is SCSI, everything in the machine is SATA.

It shows 2 instances, iaStorA.sys & iaStorF.sys




It seems I have been getting crashes again, but there is no message about the crash after bootup.

There are no crash dumps in both the zip.

But as it is continuing to crash, and the IRST drivers, the crashers for your case, are still present there, I would suggest you to go for some deeper troubleshooting.

When The AHCI (or IDE) storage controller is applied, it should come under IDE ATA/ATAPI Controllers. When it comes under a Storage controller, it is SCSI, the RAID mode driver for IRST.

Boot into the BIOS. Disable anything saying Intel Rapid Storage and/or Intel Smart Response. Double check to make it sure that the storage controller mode is set to AHCI, and nothing else.
If needed, reset the BIOS to default (clear CMOS) and apply those settings, to make it sure that the SCSI mode IRST driver is not applicable there at all.

Then perform a clean reinstall, without installing the Intel Rapid Storage drivers.

As far as I can say, that is the only way to make your computer free from this particular issue in the long run.

So I started digging around the web for anything IAstor and Intel Rapid Storage related. Apparently...there have been longstanding issues with the Intel driver over multiple revisions causing the BSODs'.

Anybody having problems with Intel's Rapid Storage Technology enterprise drivers on X79 ?

I thought I had previously installed the updated Intel driver, but when I compared what the Intel RST software said it was, and the actual Driver Details Windows was reporting, the old version was still being reported by Windows.

I am even tried reverting to the Windows native driver and installed the "new" version only to have it do the same thing.

I am going to revert to the native Windows 7 Driver and see how that works out. Most if not all of the folks who rolled back to the Windows driver cleared up their problems.

Some people did say reduced performance, but I am not running a RAID, and am not using UEFI.

Seem like a good course of action?
