...but unfortunately, you've not given us any information about your computer.. The operating system? Make and model of the computer? Laptop or destkop?
The "disk check up" you mentioned could be a precursor to a hard drive failure.. A format and reinstall of all the software should bring things back to a factory state unless you didn't install all the important drivers.. You mentioned the nvidia CD but did you also install all other drivers such as the motherboard/chipset (if not on the nVidia disc), how 'bout the sound, ethernet, and other drivers?
Hope this helps and let us know more.
my head is aching cause i dont know how to repair my computer. here is the story:
last 2 days ago i opened my computer. there was a disk check up. then after that i got a "lsass.exe" error. it took me a while before i decided to reinstall my windows. so i did it. during the reinstall, it asked for my windows cd 1st, then nvidia cd, then lastly windows cd. but on the last part, i got some errors. it says some files cannot be located. i cant locate it so i just pressed "skip". then finally my pc worked. i was so happy.
after 1 day, i had a problem again. i opened my pc but it doesnt show anything. my monitor power light just keep on blinking and blinking. i tried to reconnect all my power cords then it started. there was an error saying system32/startup cannot be found. so again, i reinstalled my windows xp. and again, some of those files were not found.
and earlier this morning i had same problem again. monitor just keep blinking and not showing anything.
here are the list of the files not found when i reinstalled my windows cd.
