Hi thanx for replying i changed the new non turbo boost ratio it was on 255 and it couldnt go any higher so i thought ok it must be the multiplier and changed it to 22 and also changed some other cpu settings but nothing to serious and then i presed F10 to save and exit and when it restarted there was no post and black screen but i could hear the system is ideling and fan spinning but not hard and power light is also on and the air coming out of the fan is hot so the cpu must be working but not in the right way,i aslo tried unpluging the cmos battery but no luck i also tried blind flash witch i couldnt even get the usb the work it had red light but wasnt blinking so not reading the flash drive with bootable files on!! And no where can i find any information about jumping the jumpers or my mobos schematics online aswell.Plz help me if u can i would be so happy and could reward u aswell
