Substantial preformance decrease after adding an old HDD

[Brolaugh]

A week ago I added an old HDD from a old laptop to my desktop PC. When I added the HDD I went from having 120 FPS in Leauge and CS:GO to 9 FPS in both. I couldn't even browse the internet in chrome without tabs crashing and freezing all over the place. I didn't think it was the HDD that slowed my PC down because it's not the main drive so I reinstalled Windows but it didn't fix it. I disconnected the HDD but it didn't fix it so now I dont know what the source of the problem is now cause everything is running at stockspeed and I've got the latest drivers.

 

Mobo: Asus Crosshair V Formula Z BIOS 1801

CPU: AMD FX-8350

GPU: Asus Geforce 9600 GT

HDD: 500GB Caviar Blue (main drive), 250GB, 160GB

RAM: 4GB

PSU: 500W FSP PSU

OS: Windows 8.1 Pro

I dont have the laptop HDD connected anymore.

Zone Alarm didn't detect any viruses or malware.

Then check for any malware, maybe you'd something in that old HDD and you didn't notice

Do you have any idea what to do now?

Are the drives connecting using an IDE cable? (One of those flat/wide cables)

Are you connecting both drives using a single cable?

If yes, yes, you'll need to wrestle with master/slave settings...

No IDE cables here.

It could be some malware sapping your system resources... Try getting avast and do a boot scan of the system...

No malware or viruses found by the boot scan.

I would remove the HDD causing the problem, reset the bios and restore to your usual settings.

If that's so, the HDD might be dying... But, it's rare for a dying HDD to affect overall system performance for something like that unless you've got something running in the background, like malware, or hyperactive antivirus software, or something else entirely...

 

I've had an experience like this with a dying flash drive... The system freezes up when trying to open it so it might be something similar... Try to listen for abnormally loud noises from the hard drive...
