Probably just a 'quiet boot' option where the boot progress and BIOS option are not shown that was turned off. Not overclocking related. And not a problem. I'd suggest just leaving it as is instead of working BIOS again.
yeah but why has it changed
Did you do anything like 'reset to default'?
usually theres an option in the bios to display full screen logo or similar--you disable it if you want to see the
my last gigabyte board had this option
wont do any harm at all if its left as it is
Must ask, why do you have Vista 32 bit? Vista is not good and it would be much better to have Win 7 64bit
it depends on the bios but both mcnumpty and wr2 are correct, he has turned on the boot logo... it wont harm your pc it also sounds like your m8/bro has over clocked your pc. if you dont have sufficient cooling then you may develop problems...
open bios and load optimized defaults to get your system back to stock performance. but you will want to check a few settings b4 you save and quit... make sure hpet(high precision event timer) is set to match your o.s bitrate (32 for 32bit , 64 for 64bit if your using win7 or vista. or turn it off if your using xp)... make sure your primary o.s drive is the first boot device. 1s done save and quit. let the dmi update and your set...
