Hey,
So i just went through 3 hard drives in the last 4 months. Now I am on the fourth one.
The first three hard drives were taking time to be detected at boot and then failed completely. Also note that only the drive with the operating system on it fails. The 2 drives with data remain fine. Maybe because the operating drive is the one always in use.
Now the last three hard drives gave up the same way. This one is acting differently. It is detected upon start with no issues and the system sometimes boots up and system stops responding and gives an error about unable to read hard drive. Then the windows boot file bacame coruppted ao I had ti reinstall windows which also failed as it got stuck during copying files and then finally i was able to install and even then while using the system it stops responding and the hard drive light goes out.
I checked power voltages through HWMonitor and the 12volt connection was only giving out 8volts.
Even now i sometimes get error unable to read from hard rive after bios and when i reboot it goes into automatic repair.
Now I should also mention that I use Anti Virus Nod 32 so i dont have any viruses.
The windows i am using is genuine windows 10 that i downloaded from microsoft media creation tool multiple times to nake sure that wasn't giving an error.
I think it might be the psu resulting in hdd failures.
Rest system specs are
C2D proscessor 2.8ghz e7400
Motherboard p5kpl-vm Asus
PSU old psu which doesn't have a brand sticker anynore and i forgot the brand. Its 550w.
Nvidia 9400gt
Ram 4gb.
So what do you guys think might be the issue? Is it thr psu causing this because of the lower voltage in the 12v conection.

Note the previous three drives are completely dead.

Also checked one more thing. If I check the voltsges from a software within Windows it shows the 12V rail giving 8V but if I go into BIOS power options it shows 12V Core ~ 12.669V

So what could it be?
