regarding a troublesome CD-RW installation, I continue to have problems after I thought I had it licked. [more inside]
Yesterday, I futzed with the BIOS and I got the computer to boot. I turned off the computer, unplugged it (it's all over my kitchen right now), and went to work.
When I came home from work, I figured I'd be sure that it still worked well before I started putting the whole box back together, so I plugged it in and rebooted. The computer whirred to life, but no image on the monitor.
I didn't change anything from time A to time B, so something is pretty clearly loose or dead or dying or something.
Is this a dying BIOS battery? I tried a little to take the battery off the mobo, but I didn't succeed. I didn't use any tools, though, so I'm sure I can yank it out to test it to see if it needs to be replaced. The computer is only 3 years old, though.. seems a little short lived for a BIOS battery, personally.
However, I can't get it to work again. I did the same commands for BIOS that I did before, and that didn't help this time. Just the one boot yesterday morning.
I've tried to change jumper settings on the hard drive (it's the only thing plugged in right now) from master to slave to cable select, moved it on the IDE cord from master to slave and back again, etc.
According to this
site, I plug in the jumper on the left most set of prongs for master configuration. However, I was using an incorrect jumper setting (I was looking at a different style of hard drive) when I got it to boot. I tried the incorrect jumpers again, but nada.
So, what changed between the time I shut it down yesterday morning and the time I tried to boot it again at about noon?
