This EZ533UA Pavilion boots intermittantly and when it does, the hard drive isn't seen. The notebook looks for a Network boot device. I installed a new ATA-6 hard drive. Sometimes I can boot from the XP CD and the XP install loads the temp files then stops at the "Starting Windows" screen... I've changed the RTC clock battery, and I can access the old 80GB Hitachi Travelstar HTS541080G9AT00 hard drive files on another system. Any ideas?
