so I have this computer, the person told me it froze so he turned it off by holding the power button, and then he couldn't turn it on again. There's nothing coming up on the monitor, the monitor is on stand by when you turn the pc on.
I took it with me and tried it on my monitor, my vga cable, still nothing on screen. I opened it up, cpu fan is spinning, and you can hear the HDD start up, but it doesn't do any loading, the loading light thing at the front doesn't flash.
It has on board graphics but I put in a dedicated video card in it, didn't fix the problem.
I got a power supply tester, tested the psu, it outputs the right voltages.
I bought and put in another motherboard, still doesn't fix the problem.
I tried to start it up with only 1 RAM stick, tried both of them individually, still doesn't fix the problem.
The HDD works, I have this sata to usb adapter, I can access all the files.
I'm running out of ideas, could it be a broken processor? The mobo doesn't beep or anything.
Edit: Removed all RAM, motherboard doesn't beep.
Edit2: For those wondering I gave up, didn't replace the CPU, the client decided to just buy a new PC since this one is quite shitty.
