After the bios, all that happens is a blinking line in the top left corner.

[Sagenumwoben]

Recently built a new pc, ran great for 2 months. Went out of town for the weekend, came home and tried to boot it up, all that happened after the bios is a blinking line in the top left corner of the monitor. I have a msi 970 gaming, 8gb ddr3 ram, a msi gtx 1050 ti, corsair cx750m psu, Samsung 850 evo 250gb, and a amd fx 8350. Windows 10 64 bit. I have tried changing the boot options to the correct drive, also even tried booting for a flash drive that has windows 10 on it and the errors still occurred. I've even went as far to unplug my ssd and plug it back in. Please help.

There are so many reasons for this problem it can make your head spin.

Any indication of a power surge/brownout problem during the time you were gone?

I'm assuming you've disconnected any other drive from the system other than the boot drive of course. If you haven't done so, do it.

I'm assuming you're unable to access the BIOS/UEFI.

The very first potential culprit, of course, is your boot drive. The most practical troubleshooting step at this time is to connect the SSD as a secondary drive in another PC and determine if it's detected. If so, test it with the Samsung Magician program. Based on our experience with at least a score of Samsung SSDs it's unlikely that's the problem - but, of course, it's possible.

Check your PC to determine all the connections are proper & secure.

If you're unable to isolate the problem your only practical recourse is to "start over" as it were. Rebuild your PC on a step-by-step basis.

Remove all your components (including all drives) excepting the MB, CPU, RAM, Graphics card, keyboard & mouse, & PSU. Reconnect your A/C cord and power on the system.

What happens? Do you get a "normal" screen display? No error messages or strange notations?

Can you access your BIOS/UEFI without any difficulty at this point and review the CMOS-BIOS settings? Check the hardware monitor/PC Health in the BIOS to determine that all temps are within normal range?

It's conceivable the PSU may be defective. Unfortunately the only definitive way to tell is to substitute another PSU, although if you have a PSU power tester that might provide the answer.

And finally, a defective motherboard. Again, only a substitution will definitively determine if that component is the problem.

Assuming all is well at this point leave the system powered on for the next hour or so, checking to see if anything untoward shows up.

Should all appear well at this point this is an indication that there's nothing wrong with the basic components of your system. While not absolutely definitive this is so, it's a very strong indication that something else is amiss.

Hopefully you'll discover the problem (and more importantly, the remedy) long before the above steps.

Keep us informed of your progress (or lack thereof).

Thank you for all the help, and I tried doing everything you said and not much of a change, I was able to get to the windows 10 install with the USB, and I tried to do the repair option but it said it couldn't be repaired. My psu is brand new, so I know that's not the problem. I can access my bios. My ssd shows up in the boot order when I go to change it but as always the same issue happens when I select it.

Now it's going to a screen that says efi shell version 2.31 currently running mode 1.1.2 with a bunch of stuff under it. Says device mapping table.

Well there is certainly a substantial change, is there not?, from your initial explanation of only getting a "blinking cursor" when you powered-up the PC.

Now, a day later, you indicate you're able to access the Windows 10 Setup files via the Media Tool flash drive (or some such) and are able to invoke the Repair command - although that failed. That's a far cry from your initial problem of a "blinking cursor" with no explanation of what has occurred to change things.

All in all it probably would be best if you would copy whatever files you need/want from the SSD to another drive (possibly one that you're presently using to communicate here on this forum) or to a USBEHD, then fresh-install the Win 10 OS onto the SSD in your new build, and finally copy the files back to the SSD.

So how would I install a copy of windows 10? I don't have another drive to back my stuff onto, but I don't mind lossing my data, but would I need to wipe the ssd before installing a copy of windows. Sorry I kinda new to this type of thing.

You don't need to wipe the SSD prior to doing a clean install of Windows 10. The installation itself will wipe the drive (you may get some warnings along the way).

 

[Sagenumwoben]

Thank you a ton, now I just have to find the windows 10 key. And I think I should be okay

 

[mjslakeridge]

If you had previously authorized this copy of Windows (happens when you log into your computer using your Microsoft ID), then you shouldn't have to input the key. When you get to the screen where it asks for the key, select "I don't have my key", and proceed. After installation is complete, Windows should connect to Microsoft and authorize itself. This is new with Windows 10.

Well I ran into another problem, now when I try to reinstall windows 10 on my ssd it's saying "windows cannot be installed to this disk. The selected disk has a MBR partition table. On EFI systems, Windows can only be installed to GPT disks" not sure what this means. This is the ssd I had windows on.
