An ASUS P5A mainboard, running an AMD K6-2 processor and WIN98SE has been trouble-free for 9 months. Yesterday, the CPU fan, case fan, and chassis fan all stopped spinning at the same time. A new CPU fan as well as a case fan were installed, and neither of these spin. However, the power supply fan does spin. All drives and cards are still working as new. I’m thinking it’s time to replace the mainboard. Any insight and/or comments are greatly appreciated. I thank you in advance.
