Thank you for your help. In standby, my powersupply fan and case fan are still running. My older Dell PC doesn't do that. The case fan has a 3 prong connector that plugs into the motherboard. Would that be a powersupply problem, a motherboard problem, or something else?
Also coming out of standby I can't click on my speaker icon in the system tray. I've read that might be a sound driver problem that can only be fixed by installing a newer driver, only problem is I've got the latest Intel Integrated AC?97 Audiosound driver, and the motherboard is out of support.
