Hi All

My pc was working fine last night. This morning no image on screen. Not even BIOS. Monitor says no signal.
Monitor works fine with 2 of my laptops.

Powering on the PC - debug cpu red led comes on for 3-4 seconds and then vga led comes on and stays.
I have 2 ddr4 ram sticks. tried with each on at one time with all the 4 ram slots. same issue.
updated the Bios from usb. same issue.

tried without my radeon 5700xt, using builtin hdmi and dp and same issue.
tried draining the power and still same issue.

any help would be greatly appreciated.
thanks

The built-in HDMI and DP ports will not work unless you have an APU processor; you have a 3600 which is not an APU.

You might try resetting CMOS. But it sounds like a GPU problem. Do you have another GPU to put in the system to see if it works?

try changing psu around 700w or more if your friend have one check it first.
or reset cmos as mentioned above and no overclocking run on stock only load default values in bios.
