Question Computer taking 10+ min to flash motherboard screen and start Windows 10

Jun 3, 2020
All of a sudden my computer started taking 10+ minutes from turning it on until windows 10 loads. When I turn it on nothing on the screen is displayed for around 10+ minutes. Then the motherboard screen will flash as normal and windows will start up. Before this issue it used to take about 1 minute for the computer to start up. I disconnected the SSD and re-connected the old HDD, but the same problem still existed so I don't think the issue is the SSD. My motherboard is a ASRock Z87 Pro4. Any ideas you have for trouble shooting this issue would be most appreciated. Thanks!
What might have changed since all was well?
One option might be to use system restore to reset your pc back to when all was well.

Perhaps something in the bios has changed?
Are you testing ram every time?
Are there unused adapters? It takes time to detect that they are not there.
Has fast boot been disabled?

Is there possibly a problem with your ram?
A delay can be the motherboard trying to find a setting that works.
Run memtest86.
It boots from a usb stick and does not use windows.
You can download the free edition here:

If you can run a full pass with NO errors, your ram should be ok.
