It’s not his HDD, bad advice mate.

Real advice: On a fresh install you need to install the video drivers and check that the machine is not throttling down...

1. Firstly, go to settings and Ease of Access and turn off Animations, Hide Scrollbar and Disable Transparency.

2. Usually I let Windows 10 update grab a temporary video driver at this point, but I would greatly recommend that you download the most current video and chipset drivers from your laptops support site regardless.

3. Uninstall any video driver Windows was using, skip this step if you didn’t let it install one.

4. Install your laptop’s mfg drivers, reboot to normal mode.

5. Do another Windows Update check and let it download and install other updates. Reboot again to normal mode.

That should be it.

Afterwards, I would check performance monitor and make sure your CPU speed looks right also, sometimes laptops can throttle down for “reasons” making everything super slow, this can sometimes be due to a battery or ac adapter issue on Dells. If the CPU speeds look like really low you could have an issue there. I sometimes use a program called ThrottleStop when this happens, but check the CPU speeds in safe mode too!!

Edit: Remove the battery and do performance tests with only AC power also!!

There have been many cases where an OS is sluggish/laggy and the underlying cause was a failing HDD. Hypothetically, in this case safe mode may not be accessing the damaged portion of the HD.

It isn't a bad idea to run CDI occassionally on any HDD as it takes only a few seconds. HDs can start getting bad sectors without exhibiting any symptoms as well before a sudden and complete failure.

Very rarely will Windows install let alone boot off a bad drive. Yes it can’t hurt to run it anyway, including a scan disk check. But the symptoms all point to drivers or throttling.

Surprisingly this is what got immediate results.

I guess those features were too much for my improper video driver configuration. I installed the final driver posted by Lenovo for the Intel HD 3000 integrated card, and sure enough Windows Update had an additional update for it once that was in place. No slowdown ever since.

Thank you!

Glad you got it fixed :)
