hello ..

i have upgraded my video card from Nvidia 8600GT to ATI 5770 two days ago .. and am having a problem with PC not booting after I turn it off for a while..The pc would boot again once I replug the monitor cable..The card works fine on games and doesnt seem to have any issues with windwos xp sp3 that am using..

by the way, When the PC boots after replugging, a dos msg appears saying : 'overclocking failed'?? , press F1 to load default values

I didnt overclock anything on my system so i have no clue why this is happening??

but Am guessing that my mobo ( which is more than one year old) must have its BIOS updated since the 5770 wasn't released until later this year..Do you guys agree? or am guessing wrong?

The power supply am using is Technoware 550W..
