Ok. So long story, not so long.
Been working on this 486 Frankenstein for months. Lots of things were wrong with it. But I finally got it generally working and such.
Last step was fitting it into the power supply cuz .. ugh issues. Anywayssss.....
I went to go fire it on after adding this new PSU, not. PSU fan would kick on , but no post or anything like that. Left it at that as I was done for the day.
Well, then the next day went to go put the testing PSU I had been using in. accidentally nudged the table and for whatever reason I deduced to keep it right on the edge. Mobo hit the floor.
ISA VLB video card was in the slots when it hit. got it hooked back up. PSU fan would kick on but the CPU felt cold, and the motherboard sounded dead. got frustrated walked away.
Today Ive been going over the board with a fine tooth comb (well, magnifying glass). found some .. "minor scratches". on the bottom, but using my multimeter everything seemed ok. no broken caps or anything.
Blew everything out with air. Plugged it back in.
Now PSU Kicks on. And the motherboard "Sounds" like it has power. CPU is getting warm... but still... for the life of me. won't post.
No Beeps. Just Turns on, keyboard flashes, and away we sit.
Any ideas?
Prior to this, sometimes I would have to turn the system on and off a few times while it was on my test bench, but I thought this could be cuz it was on a bench and my VLB card might of come loose. This mobo has no onboard video.
