Windows 7: BSOD iastor.sys, cmd safe mode only

BSOD iastor.sys, cmd safe mode only

I'm one of those many people with the BSOD iastor.sys problem. I've done my research and have done what I can with the resources and knowledge that I have. I'm running out of ideas and options to fix this problem. ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- computer tmodel: Toshiba Satellite A665 3DV ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Windows 7 Ultimate 64 bit, which was upgraded from Windows 7 64 bit Home over the summer. At around this same time I upgraded my RAM from 4GB to 6GB (the upgrade memory was purchased with the computer). Computer ran fine for over 6 months and unexpectedly it started with this BSOD. ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- What I've tried/what didn't work: ----getting into safe mode with networking, still crashes sometimes in safe mode (w/ cmd line) ----system restore to an earlier, stable state ----memory tests - 7 passes, no errors ----removing the added RAM ----Rolling Back my driver for IDE ATA/ATAPI ----Running most applications in safe mode, including PC Diagnostic. ----sfc /verifyonly, reported 100% fine ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- What is working: ----I have my computer dual booted with ubuntu 10.10, which works just fine and is what I'm currently using to access the internet. ----80% -ish of the time I can get into safe mode with cmdline without it crashing. ----copy some files to a flashdrive (a handful of minidumps and iastor.sys, iastorU.sys) ----getting to the logon screen no matter which way I try to load windows ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- ----I thought about the BIOS, which I know Windows this past week sent an update for, but if the BIOS was faulty then how can I seemlessly use Ubuntu.... So I checked out the Bios settings and nothing seemed out of place. ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- I will not have access to the computer's or BIOS's install cds for a few days since I am out of town(lesson learned). ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- I saw the instructions about posting BSOD and I'm trying to get you as much info as I can that you asked for. When in safe mode, it won't open many of the programs I am trying to run. I attached what I currently have in a zip file. Any Help? ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Thanks in advance! ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- (sorry, I don't think it is saving the formatting and looks like one big block of words. I tried to add lines to make it easier.)

I've been trying to get the networking to work on safe mode, but i haven't figured it out in the past two days. so I can't use the intel update on their site. I poked around in the intel site's manual download, but i don't think i knew exactly what to look for. when in safe mode i will randomly get BSOD too. so it makes it difficult to keep working and most troubleshooting things on windows won't work in safe mode as the error messages tell me.

Do you have anymore details on what iastor.sys does on the computer? and what specific driver do you see as having the problem???.... i have a bunch of drivers under the networking tab in devmgmt.

Ok, I'm a tech who just got a customer with this issue, machine is a Toshiba Satellite L655.

The laptop started to show the exact symptons, iastor.sys causing a stop error (BSOD), even in safe mode. I tried updating all the relevant drivers but this didn't help.

I even restored back to factory settings after backing up, I was able to restore the machine until the Toshiba apps began installing and bam, BSOD - same issue. Weird??

So anyway, I managed to get Safe mode with networking for 5 minutes and decided to run TDDSKiller.exe just to be on the safe side and bingo. Machine had a rootkit that survived a restore. Was this on the HDD before hand? Did Comodo fail to pick it up for that reason? Who knows...

How to remove malware belonging to the family Rootkit.Win32.TDSS (aka Tidserv, TDSServ, Alureon)?
