My car pc works great if the engine is off. As soon as I start the enginen I am unable to get video from the pc but the power supply fan and cpu fan is running properly.

I have 2 batteries, 3 amps, a 750watt inverter a old celeron 400 book pc motherboard with proprietarty power supply. The connector looks like a P4 connector on a new power supply but with 2 more connectors.

so its a 3x2 connector vs the 2x2 p4 connector

Unfortunatly is is a 100/240v power supply that auto switches.. Is it possible that it autoswitching incorrectly?

If if boot the pc up with the engine off, then start the car it survives crank, but locks up.

I brought a P4 Desktop from inside the house and plugged it into the inverter, and started the car and it booted right up. and worked fine, just to large for the inside of a 2001 ford ranger.

Has any one else ever had a problem getting the car pc to run while the car is running?

if so how did you fix it?

any questions or comments greatly appreciated

thanks again guys
