I got a refurbished computer around two weeks ago and it is an Dell Precision M6800. It was working fine the first few days and then after a while it started getting slower and slower. Now it takes around two minutes for the file manager to open up and it takes like five minutes for chrome to load up.

So, being the person I am, I followed the steps I usually follow if something goes wrong. Of course, I searched for viruses. I used AVG, SuperAntiSpyware, and Malwarebytes. Nothing was found on any of them. Then I ran GlarysoftPro, for any optimizations that need to be done, for example de-fragmentation and search for hard drive errors, and that didn't fix the performance issues. Even though it did find problems and fixed them with no problem, nothing was solved.

So, then I started to do other things.

    1. I restart the computer ---> No change
    2. I reset the computer deleting all personal files --> No change
    3. I reinstalled a fresh copy of windows (factory reset) --> No change
    4. I reinstalled the drivers and updated a few drivers --> No change
    5. I ran insider preview --> Worked but for around a week then it slowed again.
    6. I then reset the BIOS to default. --> It crashed once about a WATCHDOG error, but I couldn't remember it. Then, it crashed twice giving me the error BOOT_DEVICE_UNACCESSABLE. (This is all in the insider preview.) And, then I shut it down after it gave me a SQRTrails.txt or something. I didn't care, I was going to deal with it in the morning.

    Then this morning it started working, so then I went on my phone, because the laptop was still not working, and people were arguing over disabling speedstep. So, the risk taker I am...

    7. I disabled speedstep --> And it works really well, but it worked better when I first got it. I do feel the computer lagging here and there and I know that disabling Speedstep is NOT the problem. I have come to the conclusion that it is only a temporary fix.


So, I've thrown in the towel and I need some help. I've given some information on my computer below. Thank you.

The symptoms are different, but that BOOT_DEVICE_UNACCESSIBLE makes me wonder if the hard drive (or SATA cable?) is starting to go.

Is there another drive you can swap in and do a clean-install of Windows to try out?

I have ordered an SSD that is compatible with the computer. Tomorrow and will see if that is the problem. But, so far, it's looking like that is the problem.
