What I am describing by my previous post is "AC Ground Quality" issues. You can buy a simple AC ground tester at any
hardware store. But these cheap testers will only show you a totally open ground. Your described computer is a Intel six core 3.2ghz system. They are sensitive to all this grounding working right. Your coffee pot does not care, and many times old and slow computers do not care. Many users miss these simple new AC items.
In my experience, power strips should be replaced every 1-3 years. UPS battery backups once they reach 3 years use.
