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?
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.
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?
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?
You should lookup your motherboard manual or something to see what the LEDs mean. From what you say here, it sounds like the POST might be failing due to the CPU. Maybe try reinserting the CPU.
It could also be that it posts but then it should display and let you get into the bios. So not sure. It’s hard to diagnose without more info.
Sorry got busy and work. Any luck? None of lights stay on?
If not I would just double check and reseat everything, and for shits and giggles pull the cmos battery for 30s and put it back, if you haven’t already.
If nothing else works I would be thinking about RMAing the mobo.
The boot light turns on, which according to the manual means I don’t have a boot device, which is weird since a) I’m trying to boot into bios, and b) I have a fedora USB plugged in
