Hi, i get consistent BSOD when trying to use Zonealarm 4.5 on my new PC. The specs are: Mobo - MSI K8N Neo4 Platinum Ram - 2 x Corsair 512MB PC3200 CPU - AMD64 Venice 3000 PSU - Antec Neopower 480 Watt Graphics - Sapphire Radeon X550 256mb PCI-E HD - 2 x 80gig SATA OS - WinXP Pro sp2 When using ZA4.5 everytime the True Vector clients starts when the pc boots up i get the bsod. So far, i have: - Tested the hd with seatools which came up clear - Tested the ram with memtest (together and individually) which came up clear - Ensured all latest drivers for all hardware - Cleaned inside of case and most component connections - Checked compatibility of hardware - Tried different combinations of ram in different slots. After all the above im still getting the BSOD's and im beginning to think i have some faulty hardware. Weird thing is, the message changes when adjusting the ram. Regardless of which slots are used when both sticks are in i get the 8E message but when just one stick is used i get the 50 message (and thats with either stick). So im wondering at the likelihood of BOTH my sticks being faulty so im wondering whether it may be my mobo. I know this version of ZA works with this version of windows I have installed as it works fine on another PC which is running the exact same OS. I have some minidumps with both the 8E and 50 messages - if someone could take a look at them it would be MUCH appreciated. If it turns out I have some faulty hardware i might be able to still arrange an RMA. Any help/advice appreciated.
