The PC in question is a Sony Vaio VGC-RB44G. I took it into the shop to clean out all the dust caked on the board/components with an air compressor, being careful to keep it grounded even though there was no juice in it, and when I hook it back up it wouldn't show anything on screen, beeping twice quickly, followed by 6 more spaced out beeps. I know it's a code for some error, but nothing beyond that. I removed the BIOS jumper plugs and it'd boot without any beeps at all, but still no post, nothing on screen. All components have power, but it's gotta be something with BIOS. Maybe a recovery would work if I could actually get into BIOS. Tried resetting the CMOS too, nothing.
Any idea what it could be, or direction I could be pointed to get a troubleshooting guide for the chipset?
Yeah that's what I meant, the CMOS battery is what I took out. But get this, I just tried booting the system and it worked! I didn't change anything else after what I explained in my original post. Perhaps the board just needed to "air out" a little? Anyways it seems to be working well so far, posted BIOS and Windows, etc.
