Two weeks ago my drive started acting up and I did several chkdsks to repair errors.  The first round marked  a few bad sectors, the second round corrected some file structure, the third round another bad sector or two.  Then I couldn't boot anymore.  I bought a new drive and replicated it using two USB to SATA cables on a different machine and put the new drive in the computer.  It tried to boot once but got an error, so I used media creation tool to make a windows 10 install flash drive.  I plugged that in and then, nothing.  Turn on the computer and got nothing but a black screen.  Del/F2/F12/etc doesn't allow me to get into bios.  There's no Acer boot screen or anything.

 

From that point forward, it's been doing everything I could find to try and get some sort of response out of this machine.  I cleared the CMOS, I changed power supplies, I changed video cards(even tried taking the plug off the onboard vga, but nothing out of it), I unplugged everything off the motherboard that wasn't critical, I had no drives at all attached, I removed/rearranged memory(yes, I get beeps if I attempt to start it without memory), tried removing the cmos battery, tried different protect modes with the jumpers, I tried using a FAT formatted flash drive and copied P11.B1.CAP as RCVBOOT.CAP and tried the ctrl+home/alt+esc/etc.  I tried extracting the body of the .CAP into .ROM and copied it as AMIBOOT.ROM.  I tried all of that with FAT32 rather than FAT.  Did everything with PS2 keyboard rather than USB just in case it was that.

 

It sort of acts like it's alive.  If I attempt to do the emergency bios repair, if I let it sit long enough I can get the num lock key lit up(but hitting num lock doesn't change the status).

 

I'm at a complete loss.  I'm open to any suggestions.  it's been an amazing machine, it'll be even better with the 1TB SSD I have sitting here waiting on it.  I'm pulling what's left of my hair out.
