Hi,
It would be helpful to know
the version of W10 you were on prior to the update attempt: such as
v1511 b10586.545. You can use the
<windows-logo-key + R-key> command to get the run box, type in
"winver" Windows will give you the exact version and build of W10 you have on the machine. There are many going back to last July 29th (
v1511 b10240.x). If you attempted to install the Aug. 2nd Anniversary Update from ISO file, that would have worked, and I did not experience any major slow down with the latest version of AU, The build number may be different a bit, but the latest I have here is
v1607.b14393.51 as of today. My W10 test machine is 9 years old, it's a Dell OEM Dimension E520, and it boots up in less than 2 min. to the desktop/internet on 3 different hard drives.
When you ran your clean install, did you remember to run the
W10 COMPATIBILITY TEST to check for outdated drivers, apps, and hardware?
If you we suggest you do this prior to completing another clean install. Instructions on how to run the test are here:
Get Windows 10 app - Check Compatibility Report for Windows 10
If you take care of any issues reported by the
W10 COMPATIBILITY TEST, you should attempt the clean install again. Retest for bootup speed.
If still abnormally slow, you might want to test all your hardware as mentioned. Specifically should test
ALL your RAM sticks using
MEMTEST for a minimum of 8 passes; this will take from 8-24 hrs. or more if you find a failed stick and have to replace it and retest. Here's the hardware testing link I wrote:
Windows 10 - Unclickable Task Bar
Take a look at my
POST #6 which gives you all the links needed for the test and covers all hard drive types.
Lastly, it looks to me like your
PSU is a little under-powered for the hardware and
GPU and
RAM you have in that rig. I would suggest at least a 750Watt PSU. If
MEMTEST and your Hard Drive diags all pass such as
SEATOOLS, DLG, etc. your
PSU is the next thing I'd look at.
Post back your W10 version information and the results of this recommended hardware testing and we will advise further.
Best,
