Question about Dell OptiPlex GX270 PC Desktop
The problem is the follows: I can be working on the computer and the monitor goes blank. The computer still receives power as the CPU Fan and PSU fan are still running. There is however no activity on the hard disk, network (tested by pinging the machine) etc... In Safe mode this does not happen. This happens at random intervals, most often just after the login screen. I am connected to a network with +60 computers. Antivirus and firewall are working and up to date. Using Mcafee by the way. I have tried re-imaging the machine and nothing happens. As a matter of interest this problem occurs on 3 identical machines. They are Dell GX270's. I also recently noticed that if I send the machine into sleep mode, upon wake up exactly the same thing happens. The only solution is to hold the power button for a few seconds and then switch the computer back on. After a while it happens again. When this first started to occur it wasn't very frequent. After a few months of using the machine it becomes unbearable. The machines are running Windows XP Professional SP2. I have tried updating certain drivers with no success. I Have played with resolutions etc... I have stopped services, nothing. I have changed monitors, nothing. I tried swapping memory and nothing again. I have run several tests on teh machine and everything seems to pass successfully. I have updated the BIOS of the machine with no results. I have played with power settings and again nothing. I am really stuck. Help would really be appreciated. I doubt that its hardware realted only because it happens on three machines. My only thing i believe this problem could be realted to is conflict in software somewhere, but again I have no idea. These machines are a few years old. Running 256MB of ram. Its also not hard drive related. Tried swapping hard disks and got the same problem. What other information could I possibly give you?... Hmmm... Can't think of anything right now. Thanks in Advance Shawn
I had the same problem - was the motherboard capactitors.
Dell extended the warranty on those motherboards because of the fault until January 2008. Unfortunately I only found that out in February :-(
Still, I bought some replacement capacitors from www.badcaps.net replaced the faulty ones on the motherboard and all is now running sweetly.

Dell will warranty a new motherboard at N/C for the GX270 up to 5 years.

Hi is there anyway to fix the problem without buying a new one? It was working just recently. When i look at the back diagnostic light, the C lights up Yellow while A B and D are green. Does Dell give extended warranty on these since their products are a POS. Dont really have the money right now to go out and get a new one. I'm not sure if it is the capacitor issue although it could be.

Seems as though you have done everything, although you say you have played about with the power settings, in power options ensure that 'Turn off Hard Disk', hibernate, monitor and system standby all set at never. In some bios settings the hard disk is also able to be set to power down when not in use, worth checking. Sorry to not be of much help, but short of being something silly like a screen saver kicking in, but working incorrectly with a graphics driver and the screen resolution, i'm lost for a solution.
