optiplex 760 desktop
Hello Everyone,
can any one help, my conputer was stored for a while, and decided to set it up i connected all the cables then when i turned it on it bleeped very loud bleeps 6 times but the monitor comes up on screen no signal can anyone help not very computer minded.
thanks robert
JO is spot on as always. besides replacing cmos battery also try clear cmos settings by motherboard RTCRST jumper. no matter what the bleeping code comes out of the conputer (doesn't it sound better than computer) the standard no POST protocol is the same for old Optiplex or other old Dell.

Considering the age of the system and that it was stored for "a while" my first suggestion would be to replace the CMOS battery. Make sure to leave the old battery out of the system for 15 minutes before installing the new battery. However 6 beeps can indicate a video card failure and since this model has IGPU and not a discrete video card it may be a main board problem. At that point it may be worth considering replacing the system due to the age.
