And that's a good thing!
I'm just trying to learn concepts right now.
Good. Pay attention there - especially to talk about current on the +12V rail and the importance of the +5Vsb standby voltage.
I'm moving on to the power supply part of the course.
That ought to be easy for me to ID.
If not still under warranty.
I now also know from this thread that you toss the mobo if it's bad.

No, sorry, but that is not how it works. The CMOS is a separate memory device. Its purpose is to maintain "CHANGES" to the program stored in the BIOS device. The BIOS device and the CMOS are two different devices and different type memory devices. The BIOS is typically stored in EEPROMs, or similar "erasable programmable" memory device. CMOS uses a CMOS device.
For example the CMOS battery is for the BIOS when the computer is off the CMOS battery will maintain the BIOS chip.
No, that is incorrect. The BIOS stores NO hardware information, EXCEPT what is programed in by the motherboard and BIOS makers - and that is just enough to carry the boot process through to the boot drive, where specific drivers are then loaded in. The BIOS knows next to nothing about the hardware - EXCEPT basic VGA video, networking, I/O, and bus management. Your specific hardware information is saved in the CMOS.
A BIOS chip doesn't have a heat sink it only stores the information about the hard ware
No, that is not true either. Note according to the ATX12V Form Factor PSU Design Guide, Ver 2.2, March 2005 -5VDC is no longer used. And it should be noted that some PSUs use more than one rail for +12V and some split rails. And it the current on the rail that actually holds more importance.
Each PSU have 5 voltages each voltage value is related to a "rail"

2000? Well, 12 years is several generations in when it comes to electronics - especially digital electronics, and electronics that supports digital electronics.
I had a 5 year old book copyrighted 2000

There's the problem. The BIOS is NOT stored within the CMOS module. The BIOS is "firmware" stored in the BIOS "chip", or IC module, which is typically a EEPROM.
BIOS, which is stored within CMOS (a type of microchip fundamental
to most CPUs)
