well i just asked a question about my computer freezing in POST and couldn't get into bios and someone said its a computer short on the motherboard. Well, yes i built my own machine but I've had it for about 3 months now and haven't had a proble m before. I took out the cmos battery and still freezes. So, if i have a short on the mobo. what caused it? I mean all the mounts are in and i think i have a good ground. The only thing i could think is that the fan hit the floor last night near my computer but my computer was off. I really don't have any parts that i could change to change it out to see if that is it. so once it shorts, its fried?

A motherboard short usually overloads one of the voltage rails (+3.3V, +5V, +12V). Power supply detects it and causes immediate shutdown (a safety feature). Motherboard would not even have time to receive power because "Power Good" signal was not generated. This is not the case with your PC.
Try running bare minimum set up. No FDD, HDD, ODD, nothing on the PCI slots and USB ports, one stick RAM, no mouse and integrated graphics only if available. This set up should run up to BIOS menu. Also try reseating the CMOS jumper. It may have been loosened.
If nothing works, last resort could be a BIOS reflash.

I dont think that it is your motherboard, it will probobaly be your BIOS, It must have screwed up from some electro static disharge or somthing has burnt it out.
