Hi, i've recently upgraded my processor from a P4 to a Dual Core, after the update my PC had a problem with booting up,it went on but the screen stayed blank, i tried for rebooted it for several hours until i eventually gave up, then the next morning when i woke up i switched it on and WHALA!, it went on....but the C-mos checksum was incorrect and i had to set up the BIOS but after that the computer worked fine.....it regconized the CPU and after windows loaded i had to reboot for the OS to save the changes...it rebooted and everything seemed fine...until i switched it off. when i switched on the screen did not go on AGAIN, after several hours of rebooting, it finally went on with the C-mos checksum error. I dont know what to do to stop this vicious cycle, can anyone pls help....

MSI 954m3 Motherboard (Ami BIOS V5.0)
Intel Dual Core @ 2GHz
NVIDIA GeForce 8400 GS
25GB Sata Hard Drive
