Dell XPS 730x Issue.

Have you checked the cable connection between the front panel and motherboard inside the case?

Thanks for the response. Not sure where the connection between the the MB and front panel would be but I'll have a look.

Check these, for starters:

#11 on motherboard, in manual, page 3.

#13 on master control board, page 5.

Thank You

Fixed ?

Not yet. Pointed me to what I was looking for in the manual.  I have a 730x not a 730 though. #11 in the 730x diagram is the internal USB header 3 (USB). Is that what you meant? I'm trying to clear a way to see the MC board atm. Lots of stuff in he way. Thans all for the continued help.

Sorry...my bad...  I looked at the 730 motherboard diagram and not the 730x diagram. :emotion-10:

But if you look at the 730x diagram, there's an unnumbered header in approximately the same place as #11, "font panel connector" (DUH - nobody proofread the diagram :emotion-40: ) in the 730 diagram.

I assume that's the "font" panel connector for the 730x, because it's not marked elsewhere on that motherboard. :emotion-5: 

I have no idea what the other unnumbered connectors are in that same area on the 730x board.

Did you check the connectors on the motherboard too?  And there has to be a cable to the front panel, so did you check the connector on the front panel end of that cable?

You can also try clearing BIOS:

1. Power off, unplug
2. Press/hold power button for ~15 sec
3. Open case and remove motherboard battery
4. Press/hold power button for ~30 sec
5. Reinstall battery
6. Close case and see if it boots with only mouse, monitor and keyboard connected.

Dell cases use a custom connector to the front panel, so you will have problems installing a new motherboard in this case. And you're going to have to buy a new license for Windows, because the version installed on the hard drive is tied to the Dell motherboard.

Maybe you should take it to a reliable PC shop and let them troubleshoot for you.

I  checked all the MB MCB connections and reset all ram and other components and still the same issue. I guess I'll end up gutting this 730x and use the 1000w PSU/ chassis to build or have built another PC. Thanks all for the help.
