My PC can boot only if I hold F10 while it launches, even tho I have my drive with OS on the 1st place in order in bios. This problem has been since I installed Win10 on my 2T HDD this summer. (on 7/8.1 there was no such problem)
So if I hold F10 while booting, and manually select the right drive to boot (even if there is only 1 drive installed), then everything works fine.
If I just launch my PC without pressing F10, then I get a black screen that says:
"A bootable device has not been detected. Please refer to the Product Guide at support.intel.com/support/motherboards/desktop"

What I tried so far and got nothing:
1) Changing SATA slots, none of them solves the problem.
2) Changing how my PC should treat SATA connections (IDE/SATA) both in bios and Registry Editor.
3) Deleting Win10 from HDD, buying a 120 GB SSD and installing it there.
4) Going to intel website, downloading latest (5600 or previous 5599) bios updates (EXE).
5) Installing RAID Driver (when I tried to, it said that I have no Intel hardware or something like that).
5) Disconnecting all other drives except the one with the OS and trying all SATA ports.

6) Downloading latest (5600 or prev. 5599) bios updates that you can install by launching DOS from USB Flash. With this one my PC restarted and was constantly restarting every 2 secs until I turned off power supply. Then after a couple of minutes I tried to boot it and try something else, but PC said that bios update was not successful and it cannot launch windows. I don't know how, but it fixed itself and I got my old bios back that I started with. To mention: I haven't updated bios ever because there was no reason for it.
There are many other versions of bios on Intel website for my MB, and I'd try them too but idk how it fixed itself last time. So I'll try them only if you tell me that it can help.

Also, I'm not able to set my PC to sleep/hibernate anymore, when I try to wake it up, coolers start to spin, but screen stays black (stand-by). Tried different Power scheme settings, it didn't help.
CPU was overclocked (but I think that the problem with boot was before I did an overclock). Default bios settings wont help with boot.

My PC specs:
Intel DX58SO MB with (stock?) bios 2008 year
i7 920 2.67 GHz overclocked to 3.4 GHz
ASUS HD7870 Radeon 2 GBs
4Gb Samsung RAM (x2)

My PC works, but it's so annoying that I have to manually select drive when booting, I really want to fix it.
Even tho I don't know what causes that, I think that the problem should be in motherboard or BIOS. I have my 3rd drive that has Win7 installed on it, but it wont boot on it's own either (tho it used to boot normally before)

Btw: just a week ago my PC stopped recognising mic. I deleted Realtek HD Audio drivers and tried reinstalling it, and it seemed like it did, but I was not able to launch Realtek manager and there was no mic in "Recording devices", so I just bought a cheap usb soundcard and now it works through this. I don't actually lurk for a solution on this problem, but maybe it will give you some ideas on what is going on.

I already tried setting default bios settings, but if it might help I'll try removing the battery later today. Do I have to do something with the CMOS jumper aswell?

No the jumper does basically the same thing, the CMOS chip is a RAM chip, therefore it's volatile memory (the memory stored in it is lost after you take away the power) if you take the battery away that will reset the CMOS.

I took out the battery, waited ~10 mins and put it back in and it did not solve the problem :(
