Try disabling on board video card in BIOS.

I am guessing you mean the motherboard CMOS battery.

Are the speakers connected? Or perhaps it's an activation issue. Try looking in control panel, hardware and sound, then sound, and make sure your speakers are activated and your computer is feeding audio to them! =]

go into controll panel and change it to the right sound device and not the internal device and it should work hope this works,

Does anything show up on the screen when you access your BIOS?
Have you tried a fresh install?
Are there two video adapters installed (one integrated and the other in the AGP slot?

A Dell Optiplex GX270 can have either on on-board VGA integrated graphics controller or an expansion graphics controller. If an expansion card is installed, the onboard graphics is disabled.

So first, ensure that the VGA cable is connected to the correct graphics connection (If there is an expansion slot with a video connector, ten you must use that connection)

If connected to the correct port on the system, next ensure that the input select for the monitor is either set to autoselect or ANALOG

Last ensure that the display resolution of the graphics adapter will support the new monitor.

what number, i think you asking about capacitor value if so here the value its 1000 mfd 10v amd 1500mfd 10v
