dragont225, there is something unusual going on here, just as you said. For the next step, let's have you run chkdsk on the C: drive. Open a command prompt window from Start -> All Programs -> Accessories -> Command Prompt. At the prompt, enter:
chkdsk /F c:
It should tell you that the volume is in use and ask if you would like to schedule it to be checked on the next reboot. Answer Y, for yes, then reboot the system so the chkdsk will run as Windows is booting up. (If you get any other prompts, answer N for no).
You need to watch the chkdsk run, because the results will only stay on the screen for a few seconds. A good run, with no errors, will say "Windows has checked the disk and found no problems". If there are errors to be fixed, the message will be "found problems and fixed them". Keep running chkdsk until it says it found no problems. If you do see problems that are fixed, make a note of them if you can.
