I've overclocked my PC by increasing the system bus frequency from 200 to 333(266 has the same issue). Everything works fine except for booting.
When I press the power button, the PC starts up but reboots after only a second. After that it boots and works fine. Note that this only happens when I take the power cable out from the wall outlet. If I shutdown and then press the power button without unplugging the cable, the PC will boot fine from the first attempt.
I think that this may be a motherboard or power supply problem. Any suggestions?
- Intel Pentium E5200 dual-core
- Gigabyte GA-EP45-DS3L iP45 Socket 775 motherboard
- Kingston 4GB DDR2 RAM
- MSI R4850 HD GPU
- Zalman 600W power supply
Note that I'm making all of these changes in the BIOS. On the second attempt the BIOS is not resetting any of the settings - I know this because when it does reset the settings to the defaults it gives me a red message box saying that the settings were reset.
