Im sure this has been a common problem, however this is what i noticed: After I installed Windows 7 home premuim, I proceeded to reinstall a few of my apps (navyfield, ventrilo, teamspeak, and firefox). every thing worked fine except for one freeze :S I then got to dorm room and tried to hook my comp up to my samsung 22" lcd tv via hdmi cable, this worked just fine on vista, i could not get it to work so i proceded to install the nvidea drivers for my video card (yes windows 7 and 64bit version ) and every thing apeared to be fine. I setup the displays how i wanted them then clicked apply- froze =.= Tried to restart but got to windows screen then went black... nothing.. After several retry's on restarting I ended up rebooting in safe mode and restoring back to right after I installed winn 7. Got it to start sept now the brightness seems dim help? EDIT: Ok, so i reinstalled the drivers, restart comp, then seems fine. I install mozilla, I am taking a quiz for my Human A&P class because i wanna go to bed n it closes tomorrow morning, and system freezes... help?
