We have a 1 year old Dell laptop with Windows 7 Home x64.
About 2-3 months ago, it started generating random BSOD. We could not detect a pattern to indicate it was being generated by any specific program that we were using.
We did start to notice that the BSOD always had a reference to IASTOR.SYS
We have run Malwarebytes, SuperAntiSpyWare, TDSKiller, and chkdsk /r - repeatedly.
Chkdsk will run to stage 4 of 5 - where it is checking the files - and it crashes around 170,000 out of 220,000 files.
No problems rebooting or rebooting to safe mode.
We do have a good image backup (made after the BSOD appeared) as well as the boot disk.
Logs are in a zIp file uploaded to DropBox b/c its slightly larger than the 512K limit.
