OK, so I need some help with my HP machine. I shut down before I left the house like I always do. And upon coming back home, my machine will power on, but no video. I tried multiple video ports on my video card. Multiple different monitors unplugged all hardware and plugged back in even swapped video cards. No display no video. No nothing only powers on all fans work can’t even get diagnostic screen, any suggestions? I do have 32 gigs of ram.

 

 

Update: I have removed all hardware including video card and tried booting using dedicated graphics but still black screen, the monitor detects every time I plug in but then goes black

Greetings @h4ck701 

 

Welcome back to the Forum.

 

Sounds like an internal component problem; you have no video but you have confirmed the PC powers on.

 

Any HP updates or Windows updates immediately prior to current symptoms? A faulty BIOS update can cause problems.

 

You tried a different discrete graphics card and tried onboard graphics. You have also tried different monitors.

 

What additional internal components did you remove?  

 

It doesn't hurt to replace the CR2032 MB battery. This will reset CMOS.

 

I would also limit peripherals to a: monitor, mouse, and keyboard. Only connect a monitor to see how it goes. I don't think it's a USB problem.

 

Finding the bad component or components is a process of elimination.

 

You would have to look at the power supply, RAM, CPU, and MB (core components) at this point. This means disconnecting all other internal components not required to get a good POST.

 

Finding the bad component may require swapping in different, known good, core components, one at a time, to find the bad part. 

 

You could try using the HP factory memory modules. Do one HP memory module in each memory slot to check for a POST.

 

Try no RAM to check for a MB error message. No error message would indicate a MB problem or a CPU problem.

 

I usually recommend a local PC tech at this point unless you have replacement components. It's possible the MB or the CPU has failed.
