So last night Robear dropped another system down my way, and after doing an inventory of what was in it, I started seeing what I could toss in my main machine:
Radeon X1800 PCIe
Now, most of what I was doing went fine. I installed 2 SATA HDD's, and a Soundblaster Audigy2 card. I also played around with the RAM, boosting my machine up to 3GB. I booted the machine up, everything looked good, so I shut down to get the case put back together.
When I tried to put the case back on, I noticed I hadn't seated one of the HDD's all the way down, so I couldn't close the panel all the way. I pushed on it just a bit, it dropped down fine (no extra force needed), and I got the side panel on after that. The one thing I noticed here was that the CPU fan twitched just a bit, which I'm hoping wasn't a sign that I had just inadvertently shocked it.
But after I press the power button... nothing happens. I see the little green motherboard light on, so I know it's getting power. I stripped the system down to just the CPU, CPU Fan, 2GB memory, and put it on an anti-static bag on my kitchen counter to test it by itself. I hooked up power, got the little green light, then used a kitchen knife to short the jumper for the power switch... still nothing. The CPU fan doesn't even come on.
So does anyone else have any tips on something else to try? Otherwise I'm just assuming I shorted out the motherboard somehow and I'm going to have to suck it up and replace it.
