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?
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.
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
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
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?
When this happened to me it was because I forgot to plug the extra gpu power into my video card.
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?
