My computers PSU recently died. So I replaced it and all seemed ok. My computer has now started to randomly freeze,hang or run really slow. I figured this may be a HDD problem, I used the chkdsk and it found 4KB in bad sectors. I tried to clean them but with no results. I went to spinrite and HDD regen and some bad sectors were found and cleaned so I thought problem solved.
It still hangs randomly though and a chkdsk still finds 4 KB in bad sectors. I have done a check on the RAM and GPU stress test and they seem fine with no errors. The fact I have no BSOD also leads me to believe that these are still ok. The computer runs and I can even play games for some hours sometimes, it is usually Internet related when the computer decides to stop working.
Is there any reason that windows would find bad sectors when other applications wont?
Does this sound like it could be the fault?
Should I reinstall windows and see what happens?
Any suggestions greatly appreciated.
