My T61p is acting really weird

[ryanhe]

I just decided to clean my t61p, nothing much. I pulled the palmrest and keyboard and blew out the dust and after putting everything back together, i got bluescreens even in safe mode. I reformated the hard drive and tried to put a clean install of windows xp on it- no dice. it still blue screens. the one time it didn't, i managed to get the desktop and after installing the video driver, it restarted with 800x600 resolution at 16 colors. could this be connected to the nvidia graphics chip problem? my t61p has a build date of 08/06. i bought this in april and the sellers warranty is gone and so is lenovos as of june 14th(thought it expired on the 16th and when i went to extend it well i got a surprise). Any help, thoughts, suggestions anything really would be much appreciated. Thanks, Ryan.
