Re: Dell PC Desktop Optiplex GX260 Doesn't boot
Open up the case and remove any add in cards and memory modules. Try to start up by adding these back one at a time until the unit stops booting normally. The light combination is not one recognised in the user manual so I am guessing you have a non-descript fault with one of your components. Be careful when you open the case as to not disturb the ribbon to the motherboard which controls the power, I have had a very long experience trying to get one of these reconnected!

You say the power light is orange--I'm assuming that you mean the monitor. This indicates the monitor is not receiving a signal from the computer. Assuming that the computer actually powers up (fan runs, you can hear the hard drive being accessed, etc) then your problem lies in the video card.
If, on startup, you do see the BIOS info and maybe even the Windows splash screen before your monitor goes dark, then the problem lies in the video card drivers. In this case, starting in safe mode will work and allow you to download and install new drivers.
You cant.. Unless the nvidia card you added has two video OUTs. Plugging in a aftermarket card causes the motherboard to disable the onboard video..
If your nvidia card has two "outs" then you can use two monitors... most newer nvidia cards support this. sometimes it requires an adaptor, but usually it was included in the box
Bruce, the Dell OptiPlex GX260 normally will be equipped with a PC133 DDR1 128MB RAM module. It is recommended that you upgrade to higher memory bus DDR1 memory module, for example, 512MB/1GB DDR 1 running on 266 MHz to 533 MHz.
Hope this helps. Make sure u come back here if u still have further request.
first of all u need one oparting system cd. windows xp or windows vista.put cd in cd rom and boot your pc from cd dvd in first screen booting options. then make partitions install step by step OS. when u complete go to dell web page search your computer model for download drivers for your oprating system like sound driver display driver modem and all hadwares.
