I tried an hard disk monitor program and figured out that my hard drive is kind of hot (around 41 C), so I decided to clean up my box.
Then when I checked it again, the temperature was still around 40 C, but the performance dropped to 97% (before was 100% although I bought the hard drive 4 years ago).
Suddenly I sometimes get a problem where the monitor goes blank and box light is not on. Usually, I will have to turn the computer off (forced) and turn it on again.
But today was different.
After a few seconds I logged on Windows, the monitor went blank, and when I turned it on again, there was an error saying a file was missing (something like a config file in System folder or other folder).
Then that was it. The computer kept giving options like continue in safe mode (or with command prompt), last known working configuration, or run normally.
I believe you know what I mean.
So I tried to repair it with the CD.
I've never done the repair and I didn't know that it would just give me a command prompt (usually I'll just reformat my computer).
I did chkdsk and it said it found one or more errors.
Then I reformatted my computer.
All work well now except the hard drive performance being 73% now and the "work time" is less than 30 days.
I used the error-checking tool, but it said the volume was clean.
Questions:
What's wrong with my box/hard drive?
Is that because I touched something that I wasn't supposed to touch when cleaning it up?
What do you think I should do?
One thing that sprung in my mind that I had to start saving for a new hard drive
Edit: I think I should add that the monitor goes blank thing only happens if I cold-boot my PC. It won't go blank if the computer has already run for a while. Now, I'm afraid of turning my PC off
