Hello everyone! Can someone help me explain why CTRL-C does not work during XP-Pro startup to access my BIOS set-up and how to fix it. My keyboard works fine as I have used a keyboard tester program and both CTRL and C register when pressed together. I am attempting to adjust my DRAM FSB as I have chaged my RAM chips (previously 2X's DDR400 PC3200 512MB) to 3X's DDR400 PC3200 1GB. My computer was running DDR400, but now reads DDR200. Performance has slowed down about since I switched memory chips. Any assistance is much appreciated.
