Black screen on boot-up and computer automatically turns off after 40 seconds.

Hi.

I have a problem with my pc during start-up. When I start it up I have no video signal and after 40 seconds the computer automatically turns off again.

The problem started when i rebooted the pc after updating nvidia drivers. After the reboot, the screen prompted I had two options to select and I think I selected option one with the F1 key, which I believe was default settings. I then got into the bios settings which I didn't tend to change, so I exited again and the pc rebooted, then the problem started.

I think the problem is based on the video output of the computer. I do not have a screen with hdmi, so I got a dvi to vga converter, and to get that to work I had someone configuring the bios settings so that the dvi output is used instead of hdmi. I am afraid that I changed those settings back when I selected that option with the F1 key. I borrowed a screen with hdmi to see if I would get a video signal through hdmi, but with no luck.
I tried changing the bios settings to default again to get the hdmi video signal. I did this with no screen, by clicking the delete button while booting and then click F9-enter-F10-enter. The pc do not react to this until it shuts down after the 40 seconds.

The motherboard is a MSI Z87-G43 and graphics card is Nvidia GTX 660 Ti.

I hope you have an idea on how to attack this.

Kind regards,

I bet it is something to do with your hardware like broken ports on your motherboard or if it turns off it might be your PSU. Tell me how long you had your parts for and the community will try to answer :D

I assembled the computer last summer (2013) with all new parts, except for the hdd. I am pretty sure it is a bios configuration problem as explained in the first post, since the pc was fine until the reboot.

Then It might be your Operating System thats on the old hard drive. Try to factory reset your PC and reinstall you OP.

Before you do any of that remove your graphics card and try running on your motherboard's integrated graphics. I'm certain this doesn't have to do with the operating system because there's no video output before the OS actually begins booting, and the problem only occurred after updating video drivers.

I removed the graphics card now and I get a hdmi video signal from the integrated motherboard graphics. Any suggestions on how I proceed? I think I should use this opportunity to change some settings, so I can use my graphics card again.

Edit:
It worked on first boot-up. I got to the desktop and changed the resolution to 1080p, went afk a few minutes and when I came back it didn't respond to mouse or keyboard inputs. I rebooted by holding down power button and now I have the same problem as before, but now with the motherboard integrated graphics. I am truly afraid now, thought I had a possible solution for it.

That's really weird. Can you access the Bios or is there no video output at all?

I tried a few times with the motherboard integrated graphics again this morning, but did not get a vga or hdmi signal. I then inserted the graphics card again, turned on the computer and then got a hdmi signal. I forgot to go into bios settings during boot-up, so I closed the computer immediately without giving any programs, like skype and spotify, a chance to start. When I tried turning the computer on again, the same problem was back. I then noticed that when the problem is there, the keyboard and mouse do not get power as well, which means there is no USB signal either.

I figured from this, that I might be able to get a video signal by changing between the graphics card and the integrated graphics, but that didn't work either. I am now thinking, that maybe I should give it some time like I did overnight and then try again with focus on getting into bios settings to reset it to defaults.

Edit:
It seems fixed now. I pulled out the power cable to de-charge the capacitors, powered it up again and got into the bios settings. I configured it with default settings and I have succefully booted the computer several times since.

Thanks for the help.

Glad you could fix the problem without replacing any parts. If it happens again, pull the CMOS battery (little clock battery) and that should manually reset the bios.
