Solved How to fix laptop slow boot/general performance problem?

June 9, 2016 at 23:06:57
Specs: Windows 10, 4 GB
My Toshiba C55-B5362 suddenly started taking forever to start up and to load anything in general. Recently, it started to take an hour or so to start up if it starts up at all. When starting it presents the Toshiba logo, then a blinking dash, and then a black screen for about 45 minutes. I then ran a live Ubuntu disk on my laptop and stored all the important files I had on the internet via email/Dropbox ect. Then I formatted my drive and attempted to reinstall Windows 10, it was working pretty well up until the end when it took an extra 3 hours to finish up the installation. When the installation finished, I restarted the computer and the problem persisted. Although the Ubuntu live disk still works even though it might take an extra 10 min or so than it should to boot up. I'm wondering whether this is a hard drive issue, if so, how do I fix it?

✔ Best Answer
If it's a hard drive issue it is probably not fixable except by replacing it.

Test the hard drive with SeaTools for DOS (you have to make bootable media as per their instructions):

Also test the RAM while you're at it:

Rip, was hoping it was a software issue, but thank you for your help. :)

I used the SeaTools for DOS, and it merely says "No Hard Drives Found" which is obviously false.

Assuming the live CD still sees the hard drive, you could try something like TestDisk or SpinRite, but once you start seeing bad physical sectors, it's really just a matter of time.
