Is my PC not getting enough power?
Ok well, i've had my same CarPC running since last September. Spec are:
-Full ATX Shuttle An35N Ultra
-Atholon Barton 2500+ | Cooled by a Volcano 12 HSF
-512mb DDR Geil with heatshield
-Nvidia GeForce 4200 (something like this, cheap) [Used to run an ATI 9600xt]
-120GB Samsung 7200rpm IDE
-GPS USB antenna
-OPUS 150w DC-DC
-Liliput 7" TS [Runs off the OPUS as well]
Now i have my audio going out from the PC to the back of a Sony HU. Since about a month ago my PC has been acting up though. Sometimes it would just straight up shut-down after running for any given amount of time. I'd be cruising along the highway and it just pops off and doesn't come back on. However the green LCD in the OPUS would blink normally as if the ACC wire is off (as it does when my car is off), but it wouldn't come back on unless i unplugged the opus for like 30 seconds then plugged it back in.
Then the PC would start to boot up and just completely shut off before booting, or right as my front-end loaded. When i would unplug the OPUS's white plug i noticed it was very very hot, and today i looked at it and the main 12v (red, postive) pin on the male end (with the wires coming from the battery and my ACC) is brownish, not white like the others. I'm guessing it started burning a little bit or something. It's not melted, and the PC will still boot up but either completely shut down in 1 second (doesn't normally shut-down through windows) or lock-up. I have 8-gauge wire running from my battery to the Opus and 8-gauge for the GND wire as well, and even my ACC wire is 8-gauge to the Opus.
I have my stock battery in my car, which is very weak i'm guessing. It could only run the PC at shows and stuff for like 30 minuted then i'd have to start the car to recharge it. I don't know why this has recently started happening though, cause i had 0 problems up until this. Around the time i installed a 17" Dell LCD roof-mounted this kind of started happening. The LCD is ran off it's own 130w(I think) inverter, but i have a VGA Y-cable coming out of my PC to the Lili and this Dell. This is why i think it's a power issue.
What should i do?
also, ever since i started running GPS on my CarPC i've had a wierd problem with it. Sometimes i'd be running on the highway and it would have a perfect signal on a clear day, and all of the sudden it would loose it and my PC would say that there is no GPS device attached to it. But the GPS was still plugged in and the red LED was solid on it (meaning no signal). Could this be a power issue as well? Like 5 minutes would go by and it would get a signal again. Thanks
