I have a few issues going on. I have the original issue described below, followed by the fire while working on the original issue. Any help regarding either would be surely appreciated. I don't know if the two are related.
Here are the issues:
I have an older system that stopped POSTing the other day. I would get all fans and LEDs, but no POST beep and no video.
RAM (4 sticks,) video card, CPU all checked out fine in another system.
I breadboarded (kept in CPU/heat sink/fan, 1 stick RAM, video card, PS) and checked the following:
If I took out all the RAM, I would get the correct beep code for no RAM. This was true with or without video card in.
If I put the RAM back in (any stick, even known working stick from another machine,) I would get no beep code - no POST - and no video, either. This is true with or without video card in.
I also used a multimeter to test power supply. It fell into tolerances, but I know that's not the be all and end all.
I did some Googling and decided to reset the CMOS as some people said they had success with this. I figured the battery was old, so while I was at it I put in a new battery.
As soon as I plugged in and turned on the power supply, the board started up on its own, without me needing to short the Power On pins. This was not the case prior to changing the battery. Before that, it DID require that I short the Power On pins to start up. As soon as it started up, the board caught fire between the battery and the CMOS jumper pins.
I am curious as to why this would happen. I'm looking at the board right now, and the battery is correct, and seated correctly. Why did this not happen with the old battery? Was there possibly a voltage regulation issue with the board the whole time causing all the issues, and it just culminated in this event after getting a new battery?
The board is an older board - Intel D945pvs with a Pentium D 830 chip and 4 sticks of DDR2 RAM. The board was NOT overclocked at all.
So, any thoughts? Thanks in advance for any help/insight people can offer.
