PC is super slow even after clean installing Windows

[waspinator]

It's booting up slow. Installing softwares is also slow. Nvidia driver took 15-20 minutes to install. Games stutter a little at first but run smooth. Possible HDD failure? It is 4-5 yrs old. Tested RAM with Windows Diagnostic, found no errors. Temperature is fine.

Specs:
Windows 10 Pro 64 Bit
PSU - Corsair 650 Watt
Mobo - Biostar TZ68K+
Processor - Intel Core i5 2500K
Graphic Card - Asus GTX 970
RAM - 2 X Corsair 4 GB DDR3 RAM
HDD - Seagate Barracuda 1 TB

Thanks

All of the symptoms point to a failing hard drive. The fact that games are slow at first, most games load from the HDD up front, but then smooths out really points at the issue.

If I were you I would pick up a cheap SSD. If you want a really easy clone snag a 1TB SSD like this one. If you aren't using that much HDD space the 500 GB model is only $87.

The Samsung data migrations tools make for a quick clone process:

Simply hook the new SSD drive up leaving the old HDD in place. Boot the PC and Install the Samsung data migration tools to the old HDD. Clone the HDD to the SSD. Shut the PC down and remove the old drive. Then boot back up.

Thanks, I have already ordered the new hard drive.
SSD is too expensive for me.

A 500GB SSD is only $80 or so which is marginally higher than a HDD so i'm not sure how that is blowing your budget. Anyhow moving to a SSD is a nice upgrade if you can swing it in the near future as it makes boot times, game load times, and various applications faster.
