I had to do a complete reinstall of my operating system by zeroing out everything and starting fresh. I have noticed when I use my port explorer it will lag. If I click on one of the columns to move it over or just scroll through it will hesitate. The only programs I have open are my zonealarm firewall and my antivirus. I have not even reinstalled my processguard and wormguard yet. I have never had this problem before. It seems as if I don't have enough ram to pull the programs but I know that cannot be the case because this did not happen before I reinstalled my OP system and also, I have 2GB of ram so it should pull everything. I checked my msconfig to see if anything is running in the background but it only shows my ZA and AV running. My PC is only 3 years old. My PC is: Gateway 700 series X Pentium 4 Windows XP home 2GB ram Could there possibly be a problem in the bios? If anyone has any suggestions please let me know as soon as possible. Thanks so much for any help you can give me.
