Hello everyone,

 

A few days ago my computer suddenly became very (and i mean VERY) slow. To the point where starting windows explorer and right clicking my C-drive in order to check it, takes well over an hour. I tried checking the C-drive because task manager showed that the HDD was used for 100% almost the entire time. The drive check gave an 'ok', so I decided to just restart the PC and see if things would be better. This time, the pc started but there was no display at all. The monitor simply said 'no display'. After waiting for +-10 minutes, I switched off the computer by holding the power switch, and tried rebooting it. However, when it restarted I was faced with a BSOD. I tried to use system restore, but there were no restore points available, even though I was quite sure I had set it to make a restore point every once in a while... After a while I decided to do a total format and reinstall Windows.

 

After this reinstallation, the pc worked wonderfully again. For one day. That's when it started getting extremely slow again. Once again, I restarted it. While shutting the computer down, it started to process some windows updates. Upon booting again, it showed the message 'Getting windows ready. Don't turn off your computer.' for hours. After a long time, it finally booted, only to get 'no display' again. This time, I left it like that for the entire night. When I woke up in the morning, there was a blue screen telling me that Windows experienced a problem upon booting, and that I should restart the pc. Upon restarting, it booted like normal. However, it is still extremely slow. Still thinking the HDD was the problem, I ran a chkdsk and S.M.A.R.T. test (WMIC), which both gave an 'OK'. 

 

I still suspect it is a hardware problem due to the clean install not helping. However, I can't seem to identify which piece of hardware is failing. I tried running perfmon /report, but that keeps giving me the error 'The operator or administrator had refused the request.'.

 

Does anybody have any idea how to identify the problem?

 

I'm running Windows 8.1 on a home-built PC that has been working fine for the last two years. The pc contains an Intel I5-4460 CPU, Cooler master G500 PSU, ASRock Fatal1ty B85 killer motherboard, EVGA GeForce GTX 960 GPU, 8GB Crucial Ballistix Tactical RAM and a WD Blue WD10EZEX 1TB HDD. All parts are two years old except for the HDD, which is three years old.

 

EDIT: I ran CrystalDiskInfo to check my hard drive more thoroughly. It showed the following warning about the current pending sector count:

Can anyone explain to me what this means and if I can fix it?

download and test the hard drive using the WD software,

 

if you are unable to do this on that computer i would suggest removing the hard drive and connecting it to another computer to test it,

 

run the long test, not the quick one

I would backup any important data you have on the drive immediately. Pending Reallocated Sectors means you have 111 sectors that cannot be read and reallocated. If the sectors could be read you would see a number on Reallocated Event Count which is still at zero. After backing up your data then do the HDD test with the WD software mikey posted. Doing a test on a failing drive can stress it and cause it to fail.

That drive is failing. I would purchase a new one or RMA if under warranty.

That's what I feared after seeing the WD software results :(

Unfortunately, the warranty was only 2 years and the drive is 3 years old. Is it normal for an HDD to start failing at such a young age? Or could it be that I somehow caused this myself?

Today's hard drives are junk compared to what they were 10 years ago. A new drive can fail at any time. That's why it's always important to have a backup of your important data and also a complete disk image on an external hard drive. Your backup data you cannot live without should be offsite if possible.

Yesterday I've installed a new SSD and removed the failing HDD, and so far my PC has been working great again!

Thank you for helping me identify the problem! :)
