Ok here it is, I have been trying to install new software on my workstation and somehow, it fails with no error messages and restarts itself. I've tried everything, disabled applications running in the background (pcanywhere, antivirus, etc.), updated all service packs and cumulative/security patches, everything and still no luck. I know its either hardware or OS. But I can't pinpoint it. I am running Windows 2000 SP4, IE 6.0, RAM at 1GB, Proccessor is P3 1Ghz. Thanks so much for the help.
