BSOD when trying to load windows

O how I hate the BSOD! Been trying to fix the thing for about two days now. I have a dell inspiron N5110 running windows 7 home premium, I think its only SP1. I got up two days ago, turned it on, got just past the password screen and it blue screened. works great in safe mode with networking. Tried a "clean boot" as per instructions on this site- http://support.microsoft.com/kb/929135. Failed, with every startup thing unchecked. un installed the video card driver as per http://forums.majorgeeks.com/showthread.php?t=49236. It never reinstalled apparently as device manager says only standard VGA adapter now and not the HD driver that was there, but I still got the BSOD trying to load normally. So now what do I do? Last term of grad school, need the darn thing to work!! Please help :cry

This is from the little window that pops up in safe mode to tell me I had a problem. Do you need more?

 

Thank you for the guidance plodr. I have never had to deal with a blue screen before. So here is the info from the scan

This is the most recent crash, when I started up today for the first time. There are five records, all are the same bugcheck codes. It went all the way to the desk top and was there for about a minute, but then it crashed. I am still set for the "clean boot". Attached is the list of files from the bottom screen in BlueScreenView.

 

I don't know if it helps but about two weeks before this started I had another problem. If I moved the laptop at all, the screen got wide horizontal lines through it, and the computer would freeze that way. It resolved with restarting, and would load windows normally, but it kept happening for about two days. I took out the battery and unplugged it and held in the on button for 10 or 15 seconds, restarted it, shut it down normally and left it alone for two days. It had been fine until the BSOD thing started.

 

I did the system restore to five days before the issue, and now all is well. I was really worried there for a while. When I went to system restore, it turns out that there was a "critical update" on 1-30-12, which is when the problems started. I am thinking that the update was the problem, so now I have to try to load it and be careful it does not screw things up again. So frustrating! will post again when done with that, problem or not.

 

Well, no more blue screen, no updates needed according to windows update, all is right with the world. Thank you so much plodr, I hope the dumb thing stays stable. It said it is a windows update, critical update, at 02:22:45 AM. I was going to hide it, but after the restore, it does not even show up as available. maybe it crashed a lot of people and they retracted it? I have 4 optional updates, but no other ones. Go figure.

 

Here is the startup file as requested. The computer is running nicely now, after the system restore recommended by plodr. But if there is anything at start up that I can or should kill off, that's good too. Let me know.
