Here is the meat and potatos of my system

1.1Gig Athlon Asus board, 256 ram, connect to a home network through a netgear router which has bellsouth dsl Pipeing through it. I run Winxp Home on this puter and win xp pro on the other networked puter.

Now, Im not going to say that I try and download sub7 and backorifice but i do look at and download some things from the net which if i met the person who put these things on the net in real life i would not trust em any farther then i can throw them...

My question is, how do you troubleshoot your box to make SURE you are not brodcasting anything out of it you don't want to.

I use zone alarm for my fire wall, AVG antivirus, and NFR Back Officer which rarely ever does anything but smile at me.

The reason i ask this question is because when i am booting the puter i will get ghostflashes from behind the Winxp logo as it is loading and at other times. I also will get a random soft (barely audible) booop sound from my box from time to time. Sometimes its just 1 BOOOP, and others its Booop....booooop.....booop....boop then it stops. If nothing else can someone point me to a good tutorial for this subject, as i have no wish to waste anyones time...
