First of all, i wasn't sure where exactly this should of been placed on the forums so please move accordingly if this is irrelevant but the past week or so when i turned my PC on it sits on a black screen for about 1-2mins before it goes to the bios screen then the windows loading screen, i'm not really sure what it happening as i have never had this issue before and i havent changed anything recently, my monitor shows the blue light to show it's connected and has been turned on from a standby state due to the computer turning on but stays black for a little while.

I placed this issue in Windows 10 because i have had a few updates recently and it may be just a bug.
Win10Ver: 1903
OSb: 18362.592

My PC:
i5 4690k (no OC)
GTX 970 (no OC)
16GB DDR3 (no OC)
600w 80% Bronze (More than i need)
Gigabyte Z97P-D3 Motherboard
 
hdd or ssd? ran any health test?
check cpu temp?
SSD for the OS and 2x HDD's for everything else, i have ran tests on my HDD's for any bad sectors and they were all green, they both run at an average of 32 Celsius and i just ran a test on my SSD and it has no errors in the sector test and that sits on a stable 30 Celsius, as for my CPU i used speccy to look at the temps and it runs at around 50-60, this seems pretty high but unsure if it's high enough to cause damage.

I had a java game open at the time of those temp tests so that may of made them higher than the normal idle temps -- and i also need to clean out my PC a bit so that also doesn't help.
 
I just did a "smart scan" with Avast to see if i had any threats and it came up empty for Viruses and Malware, and ye i updated my previous reply, sorry about that, but they should be a bit lower but i doubt RuneScape would change the temps by that much so it's probs around that.
 
Something MUST have changed.
We just do not know what.

Some thoughts:

If your idle temperatures are in the 50-60c. range, it suggests that you have a problem with your cooler and you might be throttling.
Access the bios and look at the temperature there.
Or, download hwmonitor which will give you the current, minimum and maximum temperatures.
If you see a max temperature of 100c. there is some throttling going on.

Run two instances of cpu-z.
set one to the cpu tab where you can see the cpu speed. set the other to a stress test.
This is a simple validation of proper running.

Since you have installed some windows updates, that could be the cause.
See if you can use system restore to reset back to when all was well.

One reason for a delay before the bios screen is a ram problem.
The bios may be looking for a setting that will work.
To test your ram, run memtest86. You boot it from a usb stick. It does not use windows.
You should be able to complete a full pass with NO errors.

In the bios, there may be an option to test ram before startup.
Normally that is not set.
That would match your symptoms, but I do not see how you could have inadvertently changed that.
 
Don't use avast. Use something else at least or get in touch with bleeping computer for a full scan. Do not mess around when doing this kind of stuff. What cooler are you using would be my first question,
 
As this is a Windows 10 board discussion group and unless you are certain it's a hardware issue, rule out the possibility of a software problem by rolling back to a restore point created before you noticed the problem starting. That will eliminate the possibility that the Windows update or any recent software install is affecting you.

There are some known bugs with the 1903 Windows 10 upgrade including one I found and documented with Microsoft. If the moderator can advise me where to make the post about a Windows 10 upgrade bug, I can re-post my bug alert here on Tom's forum as well.
