I am having a problem with the Dell optiplex 755, I had to do a hard shut down due to the fact the computer was frozen. Now the PC just flashes an Amber light on the power button. I am working for a company and this is the 5th computer so far to do this!?!? Any Ideas?
We're having 755 problems as well. They are freezing when users are in Word typically. I'm not sure if it is directly related to Word or something that occurs during print preview.
As far as the Amber light, I would unplug the PC and hit the power button to 'discharge'. Then plug it back in and try and power up again. This has fixed other amber light frozen optiplexes for me before (today, in fact).
I'm convinced our Optiplex 755 problem has to do with mapped drives and the printer server being on our iSeries (AS/400). Please let me know if you guys have a similar set up.
I'm not sure what the issue is on our Optiplex 755's, but they are the only ones doing it in the company. I thought at first it was a Word issue since that is what users were in when the system would lock up. I've read several posts with similar issues but no resolutions. I had a PC half-built and was trying to get it to crash but it wouldn't do it until I mapped the network drives to the iSeries. Then I could get Explorer and Word to both hang.
I tested this theory by loading another 755 from scratch and couldn't get it to crash with just the network drives mapped to the iSeries. It wasn't until I installed the printer drivers and added the printers that are 'attached' to the iSeries. Afterwards, I could get it to 'hang'.
Specifically what we are seeing with these is if someone tries to do a print preview in Word, it will hang and be unreponsive. The user can close word via the task manager but it can't be restarted until reboot. Explorer will also hang when attempting to access the network drives. Again, the PC has to be rebooted.
I thought that it could be a BIOS issue or a driver issue with the NIC, but we have the most updated versions of both.
Okay here is what I have done to troubleshoot. I have a working machine and the one that just flashes an amber light. I put all the parts from the working PC into the none working PC including:
-Power Supply Cables
I put all the parts from the non working PC into the working one and the working one still turned on and the non working PC still did not boot. The only thing I did not swap was the mother board. So. I am guessing that is the problem.
Another Optiplex mobo issue? I would call Dell tech support and tell them what you did. I guess if you wanted to make completely sure, you could swap motherboards but if it is truly the last thing, it would be futile.
Call them and tell them the mobo is bad. Be prepared to explain everything to them again slowly and try not to get frustrated. Let us know what happens!
