Table 5-14 Memory problems (continued) Problem Cause Solution You have run out of memory Check the memory requirements for the application or add for the application. more memory to the workstation. Power LED flashes red 5 times, once every second, followed by a 2-second pause, and the workstation beeps 5 times. Memory is installed incorrectly or is bad. CAUTION: Disconnect AC power from the workstation before reseating or replacing components because there is power to the system board even when the workstation is powered down. 1. Reseat DIMMs. 2. Replace DIMMs one at a time to isolate the faulty module. 3. Replace third-party memory with HP memory. 4. Replace the system board. Solving processor problems Table 5-15 Processor problems Problem Cause Poor performance is experienced. Processor is hot. Power LED is Red and stays on. Processor is not seated properly or not installed. Solution 1. Be sure the airflow to the workstation is not blocked. 2. Be sure the fans are connected and working properly (some fans only operate when needed). 3. Be sure the CPU heatsink is installed properly.
