Recently I replaced some components in my machine (new power supply, new graphics card). All has been fine, except I sometimes now get a freeze on bootup just after the memory check. The system hangs, and I have to do a power button reset. After the reset, the system POSTs ok, does the RAID/IDE controller check ok, but then I get this message: Overclocking Failed! Please enter Setup to re-configure your system. Press F1 to Run SETUP Press F2 to load default values and continue If I press F1, my settings in the BIOS are correct, so I exit + reboot AGAIN and straight back into windows no problem. If I press F2, my settings are lost and I need to change everything again. Any ideas why this happens?
