I finished building my PC recently. when I turn on the monitor when the computer isn’t on, there’s obviously no signal and I see the bouncing logo, but when the computer is on, it says that there is no signal, and that my monitor is going into standby mode, and the display turns off. my gpu seems to be working fine, and I reseated my ram. What should I do?
Have you let your computer just sit there running for a few minutes? It might just need to memory train.
Do you get any error codes or beeps from the motherboard?
Does your CPU have onboard graphics you could try?
Make sure the monitor is on the correct input, even though they should auto switch it doesn’t hurt to check.
How would I be able to hear the beeps? I can’t exactly see an error code since I have no display
Does the motherboard have any LEDs? If you don’t have a motherboard speaker, the motherboard sometimes shows LEDs to display an error code.
It does. I notice that the CPU light turns on briefly but turns off. Is that bad?
If you can’t hear anything does your motherboard have a display? Did it come with a little speaker? Look in your motherboards manual for the best way to get error signals.
Did you give your computer at least 5 min powered on though?
No i didn’t, but my monitor shuts off every time it’s connected to my computer so I can’t wait that long
When this happened to me it was because I forgot to plug the extra gpu power into my video card.
Start with the obvious first. Unplug everything except for the power, keyboard, mouse, and graphics. Make sure that there’s only one cable going from the graphics card to one monitor. Ignore any other monitors for now.
Double check the graphics card’s power connector, and make sure that the PSU can handle the card.
Turn the computer on and see what happens. If it still doesn’t work, shut it down and move the cable from the graphics card to the onboard graphics and try again.
If that doesn’t work, turn the power off and disconnect the power cable. Double check that the RAM is in the correct slots. It will probably need to be in A1 and B1, for example, and some computers won’t start if it’s in the wrong slots. Double check that the motherboard can take that RAM at the speed printed on it, and that it’s on the motherboard’s compatibility list. I’ve had RAM cause these symptoms when the motherboard didn’t like it.
If it still doesn’t work, then come back here and post your full specs. Let someone double check that everything works together and that there are no compatibility issues.
Good luck :)
I normally see this if there is an onboard display port. If you’re not having any luck using only that port try removing the GPU and try again. Once you do get a display check BIOS for settings revolving around what to use if GPU is detected. Either that or you may really have a bad GPU?
Do you have a second monitor to test on the computer? A second computer to test on the monitor?
Try to verify each component works with known good systems. Try a different cable. Try plugging into different ports on the GPU.
Does the Motherboard give you any bios beep codes? Or show a error on a bios display?
Is the display set to the right input method? (display port, vs hdmi, vs usb-c, etc)
Does the keyboard caps lock light go on and off during boot?
You could try putting in only one stick of ram, swapping out video cards, using the onboard display output (if you have it), reseating the CPU, double checking the power supply is tightly connect to all the correct ports on the GPU, and motherboard.
