Yesterday morning returned to computer to find random green squares on the screen of my m90 precision laptop.

 

Rebooted machine green squares reappeared and then went to blue screen of death and am not able to restart computer in normal mode.

 

Can boot in safe mode - with networking.

 

Have tried loading the latest Nividia driver (NIVIDIA QUADRO FX 2500M) but no luck.

 

 

 

Also tried loading latest BIOS .07 (now .05) but get error message and does not load.

 

Any help appreciated
