So far nothing has worked and I'm completely stumped. Everything was working fine until my computer randomly crashed darker today and then froze in start up to now not displaying anything. Any help would be highly appreciated and thanks beforehand. All i've done is switched on gaming boost and A-XMP in my bios settings and got a blank screen showing no signal.
I've tried everything mentioned in that question but haven't succeeded. Help me please. I too have same problem but today morning i just pressed f8 and started startup repair and my computer restarted and says no signal.
It could be your PSU. Sometimes rebooting cleared it up but when my furnace went dead a few days ago the house temperature dropped from 70 to 37 degrees. At that temp the monitor never came on. I switched out the monitor with another and had the same results.
Thinking the temperature was a factor I ran a hair dryer on high for a minute and suddenly the picture on the monitor came on. The picture stayed on for about minutes then went black as the power supply cooled. I warmed it again and the picture resumed.
At that point I felt very confident it was the PSU so I ordered and installed a new one and the monitor and computer are both working like new. Show 9 more comments. Jimfixer jimfixer. Are you getting post beeps on startup? If not you may be dealing with a power issue. Just because your fans are running and your motherboard light comes on doesn't mean you have enough power in the power supply to run the machine.
Power supplies can die slowly and still appear ok. If you have access to another power supply try changing it out. You may also want to try a different monitor or test your old monitor on another computer.
Also you mentioned you've disconnected the power and that you've held down the power button for extended periods. Did you do this together? Finally as dumb as this is going to sound but it happens to the best of us Just sayin Hope something here helps and good luck. Thinking that temperature was a factor I ran a hair dryer on high for a minute, blasting the hot air on the PSU and suddenly the picture on the monitor came on.

After reading some unrelated advice about the "turn on fast start-up" function in Windows 10 and reading about how it can cause certain booting problems, I thought I might as well give it a try, nothing left to lose.
Voila, problem solved! After spending a week dealing with this issue and going out of my ever-loving mind, you can imagine my relief.
I'll make sure to post this advice on as many message boards I can to help other miserable souls like myself. Considering the thread is about no monitor signal after startup, just wondering how you changed the settings in Windows if the display wasn't working?
Thank you so much for this! Iv'e eaten my nails over this. I swapped everything, mobo, psu, monitor, gpu, cpu bios update etc.. The only thing that remained unchanged was Win This change in power options has worked for me. Show 8 more comments. Mark Tolman. If your motherboard has an onboard graphics card you might want to try unplugging your PCI-E graphics card and plugging a monitor into the onboard graphics card.
This will verify whether or not it is your PCI-E graphics card that is faulty or not. I talk with my techers and they tell me to remove the PCI graphic card, clean the contacts, with an ruber and a brush with soft bristles , and put that again, and now are working normally. Had the same problem and it ended up being a bad memory stick. Try removing the memory and see if you get the error beeps. If so then try one stick at a time and see if that solves the problem. The card used to work fine, and works fine in another machine.
A fresh install of windows didn't fix it. I haven't been able to find any other info about this aside from this post, could you please point me to any other info you have?

Hi, I have exactly the same problem, the monitor loses signal when Windows 10 starts. I have the exact same issue on my Gt, but only on the hdmi port.
The VGA port works fine, I D always have to pull out the hdmi adapter nd stickl it bck in to get a signal on my second main monitor too. I have this problem too. It's started on the lastest set of drivers but still persists even going back to This is not a driver issue as i have just upgraded my HD card to an RX so if your having the same issue its with windows 10 and not nvidea drivers.
Also worth noting i use dual monitors. One on dvi which does not lose signal only the hdmi. Hello, after updating to It seems it was a change in settings from the update. My problem was that if I left only the DP displayport screen connected I would see the bios screen and then the loading to windows, but after that it will just go black and I could only log in into windows using the HDMI screen.

I decided to swap stepper controllers on the Ramps 1. Unfortunately, I did this with the power on and fried the Arduino and possibly other stuff. So, I ordered a new Arduino , Ramps 1. I have no way to know if the Arduino is flashed or not. When the computer connects there is an instantaneous bump in all of the stepper motors I assume just a power surge.
