I've yet to find a diagnostic that is so good that I carry it with me. I will share I carry MEMTEST86 (http://www.memtest86.com ), the KNOPPIX CD and boot diskette for KNOPPIX and a Windows 98se boot diskette from http://www.bootdisk.com Those and a CD with Adware, Spybot, Cwshredder is about all I ever need.
Read the articles in PC World about VCom's System Suite 5 having the best diagnostic program. I still want to run Norton Internet Security and would like to use the diagnostic programs from System Suite 5. Can I use a custom install to get only the diagnostic and repair programs since I don't need the virus protection? Or, do you have other advice.
