I HAVE A HP VECTRA VL400 DESKTOP PC, MY BIOS IS IP.01.06US, I AM HAVING FREEZE UP ISSUES WHEN I'M TRYING TO OPEN TWO APPLICATIONS AT THE SAME TIME. I HAVE 512MB OF RAM ALREADY. SO I PURCHASED ANOTHER STICK OF RAM AND I HAVE AN OPEN DIMM SLOT. I PLACE THE TWO 512MB OF RAM, BUT ALL I GET IS THE BEEPS. BUT ONE STICK WILL WORK. WHAT CAN I DO TO INCREASE MY RAM CAPACITY? OR WHAT CAN I DO TO INCREASE MY ABILITY TO OPEN MORE APPLICATIONS WITHOUT FREEZING THE COMPUTER. I HAVE NORTON SYSTEM WORKS,AND FIREWALL, ARE THESE CAUSING THE FREEZE UP , OH I'M RUNNING WIN 98SE A. I HAVE DSL BUT IT'S DOESN'T WORK TOO GOOD SOMETIMES. I'VE RUN THE VIRUS SCAN AND IT'S ALL CLEAN. PLEASE HELP!
