I built this computer back during the summer with all new parts. All of a sudden like a week ago i noticed that sometimes my computer has been a little bit slower then usual. Not all the time just every now and then. Then like two days ago I went to start up my computer and it took like 20 minutes. I have Farstone restore it that starts up before windows starts up every time. And it took like 10 minutes to create a new restore point which is really weird because it usually takes like 15 seconds. Then after that I got the screen that says windows has not loaded right blah blah blah. Would you like to start up in safe-mode, from your last restore point that windows start up right in, or start windows normally? First I chose start windows normally but when it loaded everything was soooo slow and I kept getting programs not responding. I couldn't load anything. So I restarted it and chose the last restore point that was successful. And everything was fine after that. I did do a virus scan and a scan disk. Nothing wrong. Then I went to do a disk defragmenter and after an hour it was still at 12 percent which is really weird too cause it usually doesn't take that long. So I stopped it because I had to do some work. Then I played a game and after about 30 mins of playing the computer froze and I heard this CLICK from my hard drive and the computer restarted itself. And I got a black screen that said Failed to load file system driver FSDOSS.BIN. What is that? I just hit enter and it took another 20 minutes to load but i chose to start at a restore point and it is running fine now but every time i start it up i get that message. What is wrong?!?! I really need help. My computer has been really fast lately until now. It is kinda weird that this all started when my subscription to norton ended. Can anyone help?

Could be a dying harddrive. Download the disk tools (might be best to download to floppy) from the drive manufacturer and run the diagnostic. It should tell you if anything is wrong. What AV program did you run? Was it updated? Did you install a new AV program without completely removing Norton? That can cause issues as well.

I have norton and the subscription expired but i can still use it i just can't update it. I will run the disk tools. This problem is really getting worse and i am really mad. i just bought this hard drive from maxtor back in july.

I would bet it is a mechanical defect based on the clicking sounds, the maxtor tools should tell you. Sounds like it might still be under warranty also.

i can't run the diagnosic tools because i don't have a floppy drive. I know it sounds funny but i forgot to buy one when i built it and just never got around to getting it. Is there anything I can do?

Check your temperatures. That hard drive might be dying also. A clicking sound from a hard drive is bad news.

A usb flash drive might work, if you have one with software to make it bootable and if your pc supports boot from usb. Otherwise, install a floppy (they are cheap).
