Could be flat or very low battery - check with a good meter, it should show at least 11.9 volts at rest. Check both terminals are clean and tight. Check ground wire where it's bolted to the frame for clean and tight.
A fully charged battery will read 12.6 volts with the engine off. At 75% charge it will read 12.4 volts, at 50% it will read 12.2 volts, & at 25% charge it will read 12 volts. Any less and the battery is basically dead. Must be checked with a digital volt meter. It may also be the engine is to slow in time. Can also be the starter is failing.
Starter that is going bad, out of time, or weak battery.

yes
It means that there is something wrong with the engine and not the battery
to much fuel is going to the engine for it to burn it all
It's lean. You have to figure out why.
Probably trying to make a virus. It's simple: Drag the batch file you want to start on startup into the startup folder in All Programs.
If the engine is not trying to turn, it is possible that you have a dead battery.
No expert here, but when you first start your engine it is cold and needs time to heat up before it works properly. Your AC unit may be putting strain on the cold engine (stiff bearings, warped shaft), meaning that your car will simple give up at trying to run due to the increased drag on it
