    Do you really think that modifed sine wave inverter manufacturers who sell millions of units per year just get lucky when their customers buy the units. Considering that dc inverters have been around since the late 60s in the consumer market?

    Me and a whole bunch of other ppl. I'm starting to think you may be completely wrong if that's your response to my thoughts.

    The inverter can support 1000W peak spikes for upto 0.5 seconds which is why it is designed in this way. The power supply is 250W and the inverter is 300W and the pc probably only uses about 180-200W at max. So I dought its because the components in the inverter at being pushed. I have run the PC on a 140W inverter before with no issue apart from it heated up after a hour or so and shutdown! This issue did not manifest itself.

    Why are you so ademant that a true sine wave inverter will solve the problem, what is the problem it will it solve exactly?

    Ambulance's computer equipment operates on True Sinewave Inverters, I'm adament about a true sinewave (if thats the route you want to take) because I know for sure it puts out good enough power for your computers powersupply. Your current inverter is producing power that your computers powersupply doesnt like.

    Every computers power supply is different, even if they are the same model they will operate differently.

    I've got a feeling it's something to do with the inverter. My inverter plugs right into the cigerette lighter, currently I have to manually unplug it after shutdown and plug it back in to boot the computer. This is temp of course, I'll be looking into Falconey's way of shutting down soon or this Ghetto Startup/Shutdown Control for Inverter

    Anyways, sometimes I have to plug in the inverter twice. The first time nothing happens (I can see the PSU and MB and can tell if the lights come on from the driver seat). I then have to unplug it, wait for about 20 secs and then plug it back in. This usually starts it back up.

    FYI - this is because the cigarette lighter socket only provides a limited amount of wattage/amps. You need to wire it directly to the battery to get efficient operation.

    Not sure if thats true in this case or not. When I plug it in the first time I can hear the inverter beep. And it doesn't do it every time, I'd say about every 4th or 5th time. It also usually survives crank. My setup is currently temporary and when it goes perm, it will be wired directly to the battery. Guess we'll find out then.
