Thread: Computer Keeps Restarting

More info needed about your hardware. How are you powering your computer? What type of power supply are you using and how is it connected?

There could be a number of reasons. Here's one possibility: as you turn the volume up, your amps will be pulling more power from the battery. Assuming you're using an ordinary car (read: nothing too old but nothing very new either) with a standard battery, your amps will be sucking enough juice to drop the voltage of the battery (perhaps only momentarily) to a level where the laptop can't function. Computers need a stable source of power and the fluctuation caused by the amps could be your problem. But this is only speculation at this stage ...

Thanks for the reply i am using a ordinary car hyundai accent/excel (depending where you live :P) with 2 sony xplod amps one 222watts and one 666watts i have my amps and PC wired from the battery in to a 3 way distribution block then each way to each of the hardware.

The PC is a Voom PC intel atom with a M2 ATX power supply.

Today as i was driving it reset as i drove over a pot hole so I'm assuming it might have been the impact from the sub as my PC is sitting directly above the amp how ever i thought it was OK to have vibrations and movements with a CF card could it be that ram or something else is moving i guess i will keep trying to figure out :P thanks for the help so far hope to hear more

Was your volume turned up pretty loud when you hit the pothole?

Now that you've mentioned the pothole incident, I'd suggest you check all your power connections. A faulty ground connection is just as bad as a faulty 12v+ connection. Check all the car PC components and make sure they're all making good contact. The RAM sticks might be loose so take them out, clean the RAM slots and put them back in.

No it was as loud as usual when it messes up thanks for the advice i will try all that in the morning.

Also would a fault - Wire cause this even when the car isn't moving with the sub on loud because that's what happens.

If the wire is a power wire for the car PC, it can move out of place with vibrations.

I found out what it was a faulty wire inside my case the negative wire on the wiring harness was faulty and as i pulled the wires out i 4got 2 unplug the PC and short circuit something ;( RIP my Car PC lol oh well we learn with our mistakes i know to pay more attention next time serves me right.

Now i was wondering how do you know what you have shorted out im not short if i short circuit the M2 ATX or the actual motherboard or both if anyone can share some info would be glad to hear it because im not letting this from stopping me having a perfect car pc system :P

Aww that's a shame. Hopefully we can try to resurrect your system.

Which negative wire was faulty? The one from the M2-ATX? What did you do to make it short-circuit? Did you notice any burning smell or did something make a noise?

Check your cabling and fuses and try turning it on again. If nothing works, test car PC inside your house with a normal AC computer power supply.

Also, another quick tip: try to type in full sentences sentences (i.e. use full stops/periods and commas), it's sometimes hard to follow what you're saying if it's all written in one spiel without breaks in between
