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.. I didnt have this issue befor with the 8600GT

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..

Motherbrd : ASUSTeK P5K SE Intel P35.
Processor : Intel(R) Core(TM)2 Duo CPU E6550 @ 2.33GHz.
Graphics : ATI 5770 1GB
Memory : kingmax Semiconductor 2 GB DDR2-SDRAM PC5300 .
Storage : 2 x WDC SATA-II 80 GB.

Did you remember to use the hold down screw when installing the new card ? ?
Sounds like the card is loose.

Stay away from flashing the BIOS...the vid card drivers should handle the proper operation of the card.dont think it has to do with the card being loose..because now the system is booting again when I press Ctrl+Alt+Del ??

I won't mess with BIOS for either the card or mobo..but why is this happening?? after leaving the system turned off for like two hours..the system powers up but no signal stays on standby..I have to press Ctrl+Alt+Del to restart it then it would work...One of my questions remains unanswered...yea sorry patio..

The retailer who sold me the card fixed it in its place and i dont WANT to mess with that..You can at least see if the hold down screw on the top tab towards the back of the machine is in place and TIGHT...Quote from: patio on December 10, 2009, 05:39:41 PM
