I have an Optiplex 755 USFF.
System has power, and searches DVD / HDD normally when powered on. It even boots from the connected HDD (based on the HDD activity once the BIOS is through)
However no Video Signal arrives at the Monitor (and yes, the Monitor is OK :)
Any idea what the cause, if not a dead graphics chip (in which case I would expect beeps and no Windows boot). ?
Do you have an additional videocard inside of the system or do you use the integrated videocard (vga cable)? If you have an additional videocard can you try to connect the monitor to the onboard video?
Do you use dongles between videocard and monitor?
I am not sure it is even possible to add a video card to the USFF Format board, have not seen any slot on the board so far.
If there is, please point me where to look for it.
Oh yes - sorry. You are right. The USFF chassis does not offer a additional videocard option. Sorry for the misstake.
The only possibility I see is to reset the CMOS (clear nvram). Last chance to get the unit work:
Use the Jumper from the PWD and connect it to the RTCRST:
