Please i hope someone can help me :-)
i have a packard bell one two l5861 pwu6c all in one pc.windiws 7 home premium.It has i5 4gb ram 1tb hdd.
My problem is when pc posts i get 1 short beep.the machine then stops on splash screen with press del to enter bios or f12 to select boot device.now if i press del nothing will happen i have tried holding it down tapping it madley when computer fist starts up but nothing.now if i press f12 on boot it goes into boot selection and if i select hdd windows will then fire up.problem then is not all devices work on pc like sound/toch screen/cant see any usb ports in device manager.i have downloaded all drivers and installed them i have removed all hardware eccept power supply and one stick of ram and still it wont let me enter the bios with del key.if i put a disc in dvd drive and then hold del key it does try to load bios but the screen just says "please wait...." i have waited for 1.5hrs but the pc i think has frozen then (no sound from hard drive etc.)
i have cleared cmos removed cmos battery cleared me disable jumper etc but to no joy.i have tried to flash bios but got the same problem.
Im thinking motherboard but does anyone else have any ideas before i fork out on new mobo
The motherboard is a acer h67h2-ad with amibios po1-b3.
have reinstalled windows to factory settings as well updated windows 7 (done this twice)
Im pulling my hair out with this one (and i have not got alot to start with)
