Cause Solution On systems with Intel integrated graphics, the integrated graphics cannot be enabled after installing a PCI Express x16. The integrated graphics can be enabled in Computer Setup if a PCI or PCI Express x1 graphics card is installed, but it cannot be enabled if there is a graphics card in the PCI Express x16 slot. On systems with AMD integrated graphics, the integrated graphics can be enabled in Computer Setup only if an AMD PCI Express x16 graphics card is installed. On systems with AMD integrated graphics, install an AMD PCI Express x16 graphics card and enable the integrated graphics in Computer Setup. Blank screen and the power LED flashes Red five times, once every second, followed by a two second pause, and the computer beeps five times. (Beeps stop after fifth iteration but LEDs continue flashing.) Cause Solution Pre-video memory error. 1. Reseat DIMMs. Power on the system. 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. 180 Appendix D Troubleshooting Without Diagnostics
