Hello, I have an IBM MT-M 8184 and I've recently stumbled across a warning telling me that I had to run a chkdsk due to a file, not having a clue what this file was or how to run a chkdsk, I went to the Microsoft website, it told me to run chkdsk using run, cmd, /chkdsk blah blah blah. After typing 'Y' when it says "Do you want to reschedule?", I was told to restart my computer, now I have the feeling that the files that were corrupted and deleted by that chkdsk run were essential to start my computer, as I no longer can, all I can remember is that the file was in c:/users/(insert username here)/Documents and Settings/ and inside this there was a hidden folder which I had to use a 'Search' to find, you know, the thing with the inspector dog. I am running a Windows XP Pro OS. Details on the restart: When I restart, after showing all my specs for a split second (like it usually does) my screen goes completely black (like it usually does) and I'm waiting for my mouse to appear and show the log-on screen, but neither of those things happen, the screen stays black and my computer stays in the 'reading' process as I can hear that my CPU is running pretty hard (my tower makes a vacuum cleaner noise, as when it does when it is lagging a lot etc). In case you're asking, I have tried to do the last known good config and the same thing happens, I have also tried to run on all safe mode options including Safe Mode, Safe Mode with Command Prompt and Safe Mode with Networking. These 3 modes' start-ups were a bit different though, they froze on the screen where it is loading all the files on the screen, the last file I get to see on my screen is from my antivirus, which is the Free version of AVG. I have not yet tried the 'Reboot' option feeling a queasiness that I shouldn't do something else which I knew absolutely nothing about. Is there some way I can fix the start up, because it seems that I won't be restoring the deleted files during the chkdsk if I cannot start my computer to begin with. I have had my computer on for a few hours before and the screen is still black. I've also waited a few days as this has happened before but the next day I could start it again without any problems, but this time it doesn't seem to be as easy. If it helps, I have had a notice that my Windows wasn't genuine for a few months now, which has taken away my wallpaper and placed a black screen with a blue box on the bottom right corner telling me that I need to obtain a legit version of Windows, which is rather strange since my version is completely genuine, and I have installed the OS to other computers and they haven't had any problems. I hope to receive help soon as I am using my sister's laptop without consent, and if she found out, she would infact kill me. I also am trying to avoid getting a whole new computer even though mine is outdated since I don't want to raid my family's wallet since I lack a job, also a big part of why having my own computer is a necessity. I hope to receive help soon. Thanks guys.
