umm..ok...I got a real hum dinger here...I just built a pc...asus p5n-d, q6600, powerking 650w psu, 9800gt sli, 4 gb (2x2gb) pc2-6400~800MHz, 250gb wd se16, all in an antec 300 case...now it runs seemingly fine enough...but there is this annoying RANDOM beep every now and then. just a single short (1/4-1/2 sec.) beep...sometimes 2 or 3 times in a minute or sometimes 1 in 5 or 6 hours...very random...although it's always when there is drive activity...then again with this build there is CONSTANT drive activity at all times...oh and did I mention, the oddest thing about this beep, is that there is NO system warning speaker on or connected to my mobo =p ...anyone got any ideas?
