Sager 8150 - Please help! - Fan problems (with a touch of BSOD)

Hey guys, Ive recently run into a few problems with my Sager 8150 that I bought October 2011.

Issue one is that my fans recently began making a squeaking/grinding noise. I opened it up my notebook, took apart the fans and blew out any dust around them or in the motor with some compressed air. They seem to make much less noise now, if any at all. However, I ran 3DMark11 and have noticed that my temps jumped from 80 degrees celcius after a run (about a month ago) to 89 degrees for the same run... Im assuming that is due to the fans no longer working as effectively. Any thoughts or recommendations? Ive thought about lubing up the bearings in the fans, or buying new fans, but I wanted to see what other owners thought before I spent $130 on fans...

Second problem is Ive been having random BSOD, maybe 6 in the last few weeks. Bizzarely, although I use my computer 85% of the time at home, and do by far the most strenuous tasks at home (gaming), ive only ever had the BSOD while at school just word processing or surfing the web. Doesn't seem to happen at any time in particular other than that. I tried restoring from backup, restoring from restore points, and cleaning my system with a variety of malware removal tools. Any recommendations?

Any help would be really appreciated!

Note: I forgot to say that the computer was dropped once about 4 months ago. The carrier strap on the bag it came with broke (wonderful) and it fell about 3 feet straight onto tile on the bottom left corner. The computer seems to have been running fine despite that up to this point.

 

Run WhoCrashed and see what it reports as causing the BSODs. For the fans, I would say it's unlikely necessary to replace them. Have you tried repasting the thermal compound? Maybe you bumped the heatsink and possibly caused some air pockets to develop or possibly got some dust where it's causing the temp spikes.
