Please advise as to best approach to remedy problem~ I guess it would be almost two weeks ago now that my wifes laptop first had the error (tech info line is as follows): iaStor.sys - Address FFFFF8800110BF2B base at FFFFF880010C1000, DateStamp 4a287aa4. The Laptop is a year old and has had no problems previously. I dont know all the specs but its an ASUS with an Intel Centrino and running Windows 7 OS.

She reports them saying its not a harware problem, its a driver problem and it will cost $140 for them to fix it! She went on to tell me if we didnt have the warranty, the Geeks would chage $240, so we should feel better about that! lmao!!! we cant afford either ammount!

roger ~ roger put a reminder on my desktop to do that weekend after next! :-) As for the WiFi driver... if I remember correctly, I installed an updated driver just after that (when I installed a new Wifi router at home)... but, Ill check it with all the others~ Im still a lil confused how doing a Complete Rebuild (...and nothing short of doing the Complete rebuild as posted above would work!) on the BCD fixed the iaStor.sys (I didnt run/install the the new IMSM program (installing a clean iaStor.sys driver) til' after I got the system up and running! anyway...Thx Rob~ Ra

Hi, Yes its a good link. Results verifies by WinDBG, DumpCHK, and BlueScreenView. If you run BlueScreenView it will show the CAUSE of all the Feb. BSOD's was iastor.sys.

The root cause was NETw1v64.sys 7/20/2009 so look for updated to it - the Intel Wireless Driver (WiFi) - check with ASUStek if on-board and with the actual device maker if a separate device and of course Intel Downloads. Even though it was a long time ago I would update that driver.

ok...

Hi,

Yes its a good link.

Results verifies by WinDBG, DumpCHK, and BlueScreenView.

If you run BlueScreenView it will show the CAUSE of all the Feb. BSOD's was iastor.sys. Confirmed

by DumpCHK and WinDBG.

WinDBG for a couple : (all were checked)

BugCheck D1, {0, 2, 1, fffff8800112b6ff}

Probably caused by : iaStor.sys ( iaStor+4a6ff )

FAILURE_BUCKET_ID: X64_0xD1_iaStor+4a6ff

BugCheck 1E, {0, 0, 0, 0}

Probably caused by : iaStor.sys ( iaStor+5288c )

FAILURE_BUCKET_ID: X64_0x1E_0_iaStor+5288c

================================

The minidump back on 6/26/2010 was 0x000000C2 CAUSE ndis.sys which is a Windows component

which means something else drove it into Fault. The root cause was NETw1v64.sys 7/20/2009 so

look for updated to it - the Intel Wireless Driver (WiFi) - check with ASUStek if on-board and with

the actual device maker if a separate device and of course Intel Downloads.

Even though it was a long time ago I would update that driver.

BugCheck C2, {7, 1097, 406000c, fffffa8004116530}

FAILURE_BUCKET_ID: X64_0xc2_7__U33_NETw1v64+59e9

drivers, and other on-board device drivers you can. Then look for updates to the major device drivers
