Anyone know if I can get hold of a hard drive for a Dell lap top, a Inspiron 4100? My mate has one and it freezes at desk top and sometimes (not often) displayes the error message for nvidia geforce driver being "cought in an infinate loop" then blue screens. A new bios and installation of windows did not fix the problem. I thought maybe a new hard drive would fix it and I can't get to the point of re installing graphics drivers, even in safe mode.
