Monitor no signal after start up


So just today, I have this problem where my monitors does not display anything after start up. I would turn on the CPU and everything runs fine (fans, power supply, etc) but my monitors stay undetected as if my computer was never turned on.

I did some research and, so far, I've tried:

-removing all or some of my RAM and switching them through diferrent slots.

-removing and reinserting my PCI and my graphics card

-resetting CMOS through the jumper switch and battery

-unplugging everything from the Power Supply and replugging.

-pressing the CPU on/off button for an extended amount of time.

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.

My specs are-

-8 GB ddr2 ram

-quad core Intel

-nvidia gt640

-corsair tx650 power supply

Have you tried the monitor on a different computer?


i unplugeed and plugged the vga cable from both ends and then plugged them back in and it worked


Okay, so I was cleaning out my pc as per usual, so I unplugged all the cords into my motherboard, took out the motherboard, ram, gpu, heat sink, and the cpu. After reassembling my computer I have had problems. After troubleshooting, I turn on my computer and all the lights and fans turn on, but no display on the monitor, the caps lock doesn’t glow when I click it. I tried different ram, and a different gpu but the problem still persists, help please. I feel like it’s my CPU because I will leave it on to test temperature and the heat sink isn’t warm at all.

My specs:

MSI R9 390 gpu

8 gb DDR3 ram

A88XI AC V2 Motherboard

Amd - A10 7850k

120 gb Samsung ssd

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. depending on your motherboard you could try resetting the mem button common on Asus boards. 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? if not try unplugging from power and holding the power button down for roughly 60sec then plugging in and rebooting. Finally as dumb as this is going to sound but it happens to the best of us... is your monitor turned on and plugged in? Just sayin Hope something here helps and good luck

I get the some problem and tried all this metods, but don't work.

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.

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.

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.
