Hi guys!

My PC works strangely suddenly. I shut down normally one day, the next day when I started, it shut down immediately. After a few second, it starts automatically, 3 sec and shut down again. Then starts again automatically and keep going, but it won't boot up, just got a message:

"Please enter setup to recover bios After setting up Intel (R) optane memory, or th raid configuration was built, SATA mode selection must be changed to RAID mode to avoid unknown issues. Press F1 to run setup."

Since this, every time I start it, it starts like I mentioned above.

When I enter in BIOS, it is not in RAID mode, it is in AHCP mode (I have an SSD and a HDD). I try to quit from BIOS, but I can't, BIOS loads again.

SSD and HDD detected in the BIOS, but when i try to enter the boot menu it says, there is no bootable device.

Tried to remove memory one-by-one. Same.

Tried to remove drives. Same.

Tried to remove GPU. Same.

Tried to change CMOS battery. Same.

5 years old build:

Asus ROG Strix Z-390 F-Gaming MB.
Intel i5-9600kf @ stock.
2x8 GB HyperX memory.
Gigabyte GTX 1060 6GB.
Samsung 250 GB SSD.
WD 2 TB HDD.

Any suggestion?
 
A failed boot drive would not cause the behaviour that you describe so you may have more than one problem going on.

Was the computer set up in RAID, if not, do you even know what RAID is.

Can I ask how the HDD/SSD are identified in the BIOS, a Seagate HDD for example will be listed something like ST1000DM004, a Western Digital along the lines of WD10JPLX or WDS100T1BOE and a WD Black SSD SDDPNQD-512G other brands will have similar identification codes, only when such an ID code is present is a HDD or SSD actually detected and an entry simply listed as SATA HDD means that the BIOS will and has looked for a HDD in that particular boot sequence but no HDD was detected.

What is the brand and model name or number of the PSU and how old is it.

What speed is the RAM.

It was not in RAID and I don't know what RAID is exactly.
HDD is ST2000DM008-2FR102, it is Seagate not WD, my mistake.
PSU is Corsair TX750M, 5 years old.
RAM speed is

If the computer was not set up in RAID neither should the boot sequence be, just as well as it causes issues on its own, be sure that you never install RAID drivers by mistake else you will have major problems.

What about the SSD, is that detected and identified in the same way as the HDD is, if the PC is set up correctly Windows will be on the faster SSD as opposed to the slower mechanical HDD.

A decent PSU and the RAM is okay and therefore not likely to be at fault.

A system short. a power good signal between the MB and the PSU are two possible causes.

Going offline now as i've done twelve hrs today and need a break, will check back early morning UK time tomorrow.

SSD is identified as Samsung SSD 850 EVO, it is older than other parts. Windows is installed on SSD, HDD is just media drive.
Today when I started the PC to check the SSD, it started normally, but only the BIOS loaded. Still no bootable device detected in the boot menu.

Are you saying that the BIOS actually says " Samsung SSD 850 EVO, "

It will be a world first if it is.

Can I ask that you do not quote every reply as we have to read the full post to make sure nothing gets missed,, thanks.

That is good and bad news.

Good because it is actually detected which suggests that the SSD may be okay, it wouldn't be if it were faulty in any way, but bad because it likewise suggests that Windows is hosed.

Other than Windows do you have any personal data on the SSD.

Do the below for us before you post back with the answer to the above.

Restore the MBs default factory settings in the BIOS, they are sometimes listed as one of the following " factory defaults" "most stable" or on newer boards "optimized" please note that if you have both the "most stable" and the "optimized" options in the BIOS you should choose the most stable" option as in this instance the "optimized" settings are a form of overclocking that can cause instability.

Save the new settings, exit the BIOS, restart the computer, post back with an update when you are ready.
 
I have some personal data on the SSD, would be nice if I can save that, but not necessary.
I only found optimized default options. When I quit from BIOS, the following changed:
TPM Device Selection [Firmware TPM] -> [Discrete TPM]

It restarted 2 times automatically, then BIOS loaded again.
 
If you want to try and save the data you can boot from something like Linux Mint see info here

Just a fyi, Windows should always be installed on either its own drive or on a separate partition on a larger drive, this reduces the amount of free space that is required to be kept available + it makes creating a regular back a whole lot easier.

A 256GB SSD or separate partition on a larger capacity drive should be the minimum capacity allowed for.
 
Good news on the files but due to unforeseen circumstances beyond my control I am unable to afford the time time to assist on the forums for a day or two, apologies for any inconvenience that this may cause and thank you for your understanding.

I should be back am UK time tomorrow and meanwhile I hope you are able to secure your personal data.

Suggestion, get yourself a bootable Windows ISO on a USB flashdrive, see info here
 
Okay, keep us posted and if you know that you will not be around for a while can you let us know so that you do not get asked for updates and/or your thread being closed due to lack of activity
