Well it doesn't sound so random from your description. What is your 12V running at? Down to 11.5 is usually okay.

12 volts is where the cpu gets its power so if it dont have at least 30 amperes then that could be a problem

Are your speakers powered by your PSU? Also have you disabled your onboard sound in the bios? Methinks it has absolutly nothing to do with your psu.

pbasil1- Ease up, the thread is only 2 days old.

gtjr_ph- 30 amps isnt the magic death-to-cpu number, depending on how many extra things you have you can get away with 24 amps or less.

I'd say 18 amps is plenty enough for any mid range system. Mine in the sig used to run just fine on 14A and it didn't have any problems that were resolved when I got a better PSU. Also another friend of mine has a P4 2.8 and 6800 on a 350W (16A).

bxjohn, most likely the new sound card is conflicting with something else on your motherboard. Try disabling sound and/or updating your bios.
