Have you tried a different kernel?  Installing a different one if need be.  Could be a graphics error.  When you get this blank screen can you get to the console via Ctrl-Alt-F1?

Thanks for the quick reply. No I have not tried any other Kernels because I don’t know how to do it. And I don't think there is any console available because CPU light is completely dead at that moment. What can I do now?   

When it boots into grub, should be a boot menu.  If there is a different Kernel it be in that list.  Anywhere from 1-3 different boot modes, usually a fall back, the Deepin Default at the top.  Windows at the bottom.

Well unless its completely locked up a black screen usually means it can't connect to an x-server (The graphical environment)  Hitting Ctrl-Atl-F1 would then take it to to terminal.  There is an option to edit the boot menu line and boot to the terminal and not start the x-server.  I'd have to look that up.

The problem is not about loading graphical environment because the processor is not loading anything at all, it is just blank for some time (The indicator red light is not even turned on for a second) and restarting automatically.

I figured out that Ubuntu has exactly the same problem as Deepin (after updating kernel to latest version the problem still exist), but Manjaro linux is working fine every time, so what is the problem...? I think the problem is with my hardware but there should exist some workaround to fix this issue.

So both Deepin and Ubuntu run fine after installation.  But crash probably after a Kernel update?  If the boot menu isn't giving an option to chose the 4.2 kernel or the 4.4, which would list advance boot options for deepin.  You can try reinstall and lock the Linux-image at 4.2.  But I get a default Kernel at 4.4 and 4.2 under the sub-menu.

You stated you can get to the Grub boot Menu?  I see now, I missed you were using two drives.  Try configuring your PC to boot the Linux drive first, then reinstall, possibly still try locking the kernel.  It may not be correctly mapping your root, home partitions, (when the order changes in the Bios the mapping needed for the OS changes.  Or try adding Linux to the Windows boot Menu.

Its quite possible Grub can't find your Linux Kernel if the mapping changed!

I personally would just set it to boot the Windows drive at SDA, install Deepin to the second drive, Grub to SDA.  In this way your not changing the Boot device at startup to change drives, therefore you shouldn't have any mapping issues.

I have a similar setup with Windows 10 on one disk and Deepin and two other distros on a 2nd disk. Maybe you can go into your pcs Bios, F2 or similar, prior to booting and change the efi boot priorities to have the Deepin disk boot first, and if you are able to boot into Deepin, perform a sudo update-grub and reboot. On my pc, the Deepin boot loader gives me the option to boot into any of five distros, including Windows 10. Also, if I remember correctly, when I installed Deepin on a separate disk, I disconnected the Windows disk before installing Deepin on its own disk, for even with two separate disks, Windows 10 attempts to control both disks, including bootloaders. Try reconnecting disk , then booting into Deepin and updating grub. I do not know if any of this will work on your particular pc or if some other problem is the cause. Perhaps a more experienced forum member can give you a hand. Good luck.

windows sucks!)))

Indeed. Microsoft thinks it owns my pc and can do or break whatever it so desires. That is why tried to isolate Windows on its own drive.

Yes windows 10 is horrid, built in spyware and who knows what else.  Its junk get rid of it, use 7 if you want Windows.  I don't have any problems with 7 instaledl on the same drive as Linux.  But don't use it much, occasional game.  Just a game platform to me like and Xbox.  lol

Actually No.... they crashed even after kernel update (and before kernel update too) but the crash is occasional, I can boot into deepin after 1 to 3 attempts now.

I will try your methods later tonight. May be there is a mapping problem as you stated. But if grub can not map things then why it booted after some attempts ?  Sound suspicious.

I can boot into deepin after some attempts and I updated grub many times, but it is not effecting anything at all.  Yes grub is not only detecting os from current disk but also from all other disks attached to the pc, that is good. I thought about that disconnection method but i am too lazy to do it, but it seems now i have to do it :/  .... Thanks for your suggestions bro.

It is a hassle and there is probably an easier, technically correct method. For what it is worth, after reconnecting W10 and rebooting, I now had a boot screen with the option to boot into W10 or the the other disk, which when booted into gave me a Deepin boot screen with my 3 Linux distros as options. I booted into Deepin, updated grub, rebooted, and then had the Deepin boot screen with all of the distros, rather than the two disks, listed as options. Everything has worked well since then.Also, somewhere on this site is a tweak tool offered by Deepin that sets W10 time to UTC time. It came in handy because W10 time was always off every time I booted into W10 after getting things set up. Good luck with the setup.

Yes that time related bug is pretty common with linux. But currently i need some luck, because i'm running out of luck. My hard disk is very close to a failure (as suggested by SMART) and this is why i am not using it until i get a new hd, that is fuking unlucky. I am not a big gamer so I only need Windows for Photoshop and that's it (Gimp is a shit), hoping that some Chinese app developers will make a Photoshop clone like WPShop (:p) in near future...

Hope your new HD cures your problem(s).  I, too, only keep W10 around to use with my printers and a few other programs. Deepin will probably offer a Superior Photoshop app in the near future. Good luck with the new HD.
