Can't tell if problem is my monitor or my psu

[MilkyMilkMan]

A few days ago when i went to turn on my pc i had issue where my pc was running but i had no signal from the monitor.

I knew that my pc wad working and I heard the fans spinning,saw my psu spinning and my gpu spin and light up.

I use a 350w psu that just meets the requirement of my rx460.

My monitor is fairly old, came with a prebuild pc and is an asus 19 inch vga input.

Ive tried changing the vga cables around and even used a new one (i use a vga to hdmi adapter but i don think that is the problem)

I am planning to buy a new monitor since i think thats more liekly the problem but if you guys have any useful information please do share.

EDIT : i took out my gpu and put it back in after doing this my momitor switched on and an asus loafing screen will pop up for one second then my screen will go black again. When i press f1 to go to bios settings it pops up for a second aswell before going into a black screen again. Also if i switch of my monitor and switch it back on it turns on for a second before going back to a black screen

Did your VGA to HDMI adapter come with a USB power cable? If so, try using it and see if it works. If not, it's possible there's a problem with your GPU drivers, but the trick is uninstalling the drivers. You need your display on to see the menus. Try using a different display if possible before buying a new one, to save money, and to make sure it is the monitor that's causing the problem.

Don't believe my adapter came with a usb power cable, I use a startech one.Since i do not have a spare display should i attempt taking my gpu out and putting it back in position

Question from MilkyMilkMan : "Problem with monitor or psu?"

A few days ago when I switched on my pc, my monitor would turn on for a second and then go blank however the green power button was still there and my pc was still running.

I Thought this was a problem with my vga cables so i tried taking them out swapping them around and it got to a point where i had no signal on my monitor.I bought a new vga cable but that did not work aswell. after some fidgeting i made my old vga cable work.

However I still had a blank screen
After 1 second of turning my monitor on, every time I switch of and on my monitor it works for 1second before going blank again.

My pc is still running as im still able to log into my account, type password, go to desktop etc.

I can't tell if this is a problem with my monitor such as the blacklight being burnt or if my psu is failing?

I don't think it your PSU as you PC is running fine. Please list you PC specs.

Peace.

Specs

Gpu : rx 460
Cpu : i3-3240t
Ram : 6gb
Psu : 350w (non-branded china one)

I use a startech vga to hdmi cable to comnect my gpu to monitor

Try connecting your VGA directly to the motherboard and check if it works. Please specify your motherboard as well.

Peace.

I have an asus k5130 motherboard.
Im afraid im unable to plug my vga cable into the mobo as i have broken the cylinder part where the side screw of the vga cable goes into

So ive tried looking around in other forums and doing some research but I just can't seem to find a solid answer to my problem.

When I turn on my pc, my monitor works for one second before going blank, there is still a green light and every time i switch off my monitor and turn it back on it works for a second before going blank again. my pc is sill running as im able to go onto the log in screen enter password and go to desktop which i can see during that one second my monitor shows something as I turn it on.

Im unable to tell if this is a problem with my monitor, psu or something else.

Swapping the vga cables and even using a different one

Unplugging everything and replugging.

Taking out my gpu from its slot and placing it back

Cleaning the psu and cpu

Taking out the vga to hdmi adapter and putting back in.

Holding onto the power button and even spamming it with and without power cords for both pc and monitor.
