Ok. so out of no where my moms monitor stops displaying the computer. So I first tried to use another monitor and that wasn't it it still did not shot no signal. So I was like dang its probably the gpu, I bought a brand new gpu and still no display showing up. I then bought a new PSU and still no display, everything powers up but no display at all the monitor just says no signal So I replaced the memory. Still no display. I am completely lost and have no idea what to do.
