Ok, I apologize for the length, but I want to provide as much info as I can to best describe my problem and there is a bit of history to it. First thing is my system is about 3 years old, but has been running like a champ. The problem first arose when I started to see major slowdowns in Windows performance. It would take me forever to do anything. I then started to see popups declaring that files were corrupt and that I needed to run chkdsk. My system would sometimes randomly reboot and I was unable to run chkdsk (without error fix) while I was booted up because "Windows or another program has locked this drive...". Soo, at this point I suspected it was a virus and/or just hard drive failure. I bought a new drive, installed windows and everything was working fine for a day or so. I started to get registry errors on the new install, and chkdsk was successfully running and repairing many errors (on a brand new drive and install!). I started to experience slowdown again, and programs that were freshly installed would be corrupt and unusable after the restarts (I couldn't even uninstall them). I had at one point, booted the system with both drives connected, thinking to transfer files. I was unsure whether the potential virus may of been transferred to the new drive. So, I decided to delete my partitions and start over again. I did this and successfully reinstalled. However on the second reboot of the system, it could not find files in the Windows/system32/ and wouldn't boot up at all. I tried to repair or reinstall from the windows CD and I get a registry error blue screen that won't even let me enter the CD repair functions to repair XP or repartition the drive. I'm stuck, what do I do now? BTW the old hard drive is still bootable.
