When I try the usual F-Keys at startup, the startup is delayed, but no bios or other messages. When I try via advanced startup, there is just a black screen that never goes away.

@mrmaid -- no messages ... black screen
- failing power-supply -- not supplying all of the various voltages to the various components;
- failing motherboard;
- failing processor;
All are "major" problems. It is not easy to find a replacement motherboard, and it can be expensive to find a processor that is compatible with the motherboard. Temporarily connecting an alternate power-supply is not too difficult.
Disconnect the cables from disk-drive, CD/DVD drive, Ethernet cable, speakers, USB printer, USB mouse, leaving only keyboard & monitor attached. Then, try power-on. Anything?

@mrmaid - do you have a valid justification to update the BIOS? I have seen an excessive number of posts on this gathering where a bombed BIOS update has "bricked" the PC. My proposal is to make an effort not to refresh the BIOS.
