Driver equal and less than zero problems are both MS Windows problems, possibly related to x64. Standard Windows Update should solve those issues.

The Limeware restarts my PC problem is a little different.

I have NVIDIA nForce 10/100/1000 ethernet. The actual driver seems to be the problem when Limewire Pro 4.12.6 and Java 1.5.0_03 are used. I've been hesitant to upgrade due to the "Pro" part.

Java 1.5.0_03 has known bugs and security issues. I've seen in other forums that you can't update the JRE without updating the Limewire software. This specific JVM (and about the 7 revisions after it) had memory resize problems.

The next step is to make sure you have the latest and greatest nic card drivers from your vendor. My computer restarts pretty regularly (without a blue screen) when I have 8+ downloads with 10 hosts each with "Turbo-Charged" connection enabled. There's some interaction between the hardware, the driver, Java, and Limewire that gives an fault.

The third step is to understand what you are downloading. There's a lot of junk and trojans out there. Very old virus scanners with "smart" behavior or script detection will shut a computer down immediately if there's suspicious activity.

Hope this helps.
