BSOD on my Fujitsu S7020D

Well I was chatting on yahoo on my laptop when all of a sudden my screen went blank. I restarted the computer only to be greeted by the blue screen of death saying "Driver_IRQL_not or equal to etc" and the filename IASTOR.SYS.
After 5 reboots I was able to get into my computer BUT it had defaulted to old settings and some of my desktop program icons were there and some were misssing. I am the only administrator and person who uses my laptop, and I did not add or remove anything recently. Anyways, when I clicked on my pictures, it was empty and when I clicked on internet explorer, all my favorite sites were gone. I looked at C:\Documents and Settings\Administrator and indeed all my photos and favorites were there, but not in my C:\Documents and Settings\MSK-Laptop which is where things were before. So I copied those contents over from administrator to MSK-Laptop and all was good for a bit.
When I clicked on outlook, it treated me like a first time user asking how I wanted to set up my accounts, and when I clicked on Yahoo Messenger, It also treated me as a new user. So apparently all my settings were not transferred over.
Now the kicker...I decided to go do a system restore and when I selected last week, it froze on my and gave me the SAME blue screen of death pointing to iastor.sys. When I tried to create a NEW restore point, it gave me the same message.
I did a quick search on IASTOR.sys, and it seems to be a Intel Application driver? Whats going on?
I looked at user accounts and I am the only one on it, but somehow some "memories" associated with program data are missing. I hope Im making sense, cause its tough to explain fully. Any help would be GREATLY appreciated

What confuses me is that each program I run now, it thinks this is the first time Im using that program. For example I started strrets and trips, and it led me to the introduction new user page. When I went to play solitaire, it had resetted my high scores, and when I ran Windows media player, the computer thought I was running the program for the first time.Whats concerning is that I am now unable to create a new restore point for future crashes, because when I try to create one, I get the BSOD

BTW A phone call to Fujitsu was useless, they told me to reformat and start over, I do not feel this is a viable option.

 

Bump
Any advice would be appreciated...

Well now I'm getting random Blue screens of death with the following:

Stop 0x000000D1 0x00000018 0x0000002 0x00000000 0xf81f425f
iastor.sys- Address F81f425F base at F81E5000, Datestamp 42b2df42

 

I was plagued by BSOD with this unit but the error message referred to the wireless card. I wish I could give you some help here, but we never could figure it out (and by "we" I mean many Fujitsu techs and even the people at Portableone). Fujitsu tried everything with mine- 3 motherboards (don't ask..), hard drive, new wireless and Bluetooth cards, and assorted other things they damaged along the way (like a new speaker assembly and LCD even). After all that, the BSOD reappeared...after 3 months the computer just wasn't holding up and the intermittent crashes were intolerable). It took some doing, but they ultimately gave me a complete refund.

Wish I could help, because I understand your frustration. Fujitsu will not take this seriously unless you reformat. Buy a cheap external hard drive, back up your data and reformat. The waste of an afternoon, although I, like you, would strenuously avoid it, is probably less than the time you've been wasting on this issue. Call them about reformatting if you decide to do that, so it will be on record that you reformatted. That way, if it doesn't resolve the problem, you won't hear "reformat" again. Several others have complained about BSOD with this machine and I wonder if there is something not quite right somewhere that they haven't bothered to find out about.

Good luck!

 

I was having the intermittent BSOD crashes as well but the culprit was the Atheros wireless card driver. I have installed the latest driver, 4.2.2.14, from the Fujitsu web site. So far so good (no BSODs in a week).
