    i have no probs with my system and i don't use any circuits. I run an inverter to provide power to my PC and i'm assuming you do too. My inverter is hooked up to a switch on the dash so when i turn it on it comes on, turn it off and it's off. No hook up's to ACCESSORY line off the ignition. Is your computer set up to Boot as soon as you turn the key? if yes then try disconnecting the ACC line and hook your inverter up to a 12v line directly to the battery. Then test your system again, if it still reboots while cranking the engine maybe your alternator or battery is dying.
    Got nothing to lose but 15 minutes so give it a try.

    no i use a sproggys mk2.5 dc - dc donverter , the system reboot cos the starter motor causes the battrey voltage to ddrop below 8v which is where the feed back regualtor in sporggys psu doesnt provide 12v = from!

    um i believe a tank circuit is just a capacitor in series with a diode....

    pretty simple stuff, just make sure u get large enough components to handle the loads..
