My Dell Optiplex gx260 Pentium 4 Flat CPU doesn't Display anything, and Power light is Orange.. Please help me out


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.

Why is my dell optiplex GX260 CPU fan is very fast ?


Usually the fan regulates its own speed (or rather the BIOS does) in relation to the current heat, you may have heat/environmental issues, or power issues. However I would first check to see that the fan speed isn't statically(permanently) set to a high speed. You can check this in the BIOS, as the machine starts up it will flash a small message ( For Setup or For Setup, something like that), hit the stated button to enter your BIOS, under 'Thermal' or 'Hardware' you should be able to find fan speed.

15 to 20 mins screen will go blank and will have A black screen reboot and it will work 10 or 15 mins. RELOADED XP AND THIS DID NOT HELP, SAME PROBLEM


Your Dell OptiPlex GX260 PC Desktop computer is overheating. It is shutting itself down to prevent component failure.

Ensure that the Processor heat sink is clean of dust so sufficient air can flow through the heatsink and cool the processor.

Install additional fans in your computer 120mm are best but 80mm fans will do fine.

Clean the computer chassis of dust as well.

Thanking you

Loud "jet engine taking off" type sound


If you changed out the power supply then the only other device that could be making that noise is your CPU cooling fan. To be sure, open the case and disconnect the CPU cooling fan plug from the motherbrd (MAKE SURE POWER IS OFF) and see if the noise stops. Don’t worry about the “Fan Failure Error” when you turn on the computer. Just hit F1 to continue. Don’t leave the computer running without the fan plugged in longer then necessary. After tying this procedure, please contact me for further diagnosis.

Orange Light permanently on motherboard. PC won't start


1. motherboards for atx form factor pc's are powered even when the computer is off, particularly if you leave the computer plugged in to wall outlet... you better do not work on you computer while power cable is still connected to both, your pc and the wall outlet..

2. I found this thread that may be helpful, it may be the motherboard may have gone bad, cmos is corrupted or something may not be seated properly...it could also be one of these: Bad CPU, BAD ram, Bad power supply.. read the thread for details:

My hp dc 7600, stop to work and now don't power on. When I press the power button the computer start the fan cool and then turn off.


Big chance you've got a broken motherboard...
Maybe your CPU is broken...

Check your motherboard for 'swollen capacitors'.
Instead of flat, it will have a convex top.

You can also have someone who knows a bit more of computers look after it...

Reference the Power LED States
Dell OptiPlex and Dimension computers and Dell Precision workstations have incorporated the use of the multi-state power button LED as a hardware status indicator. The power button LED illuminates in two different colors and can also blink, which allows for indication of five different system operation states. (Table 1)
LED State
System State
Steady Yellow The power supply is functioning, but the system is not processing data. This may indicate an issue with the system board or CPU. Blinking Yellow The power supply is receiving power from the source but is unable to properly distribute it to the components. This may indicate a power supply problem. Steady Green This generally indicates that the system is functioning normally. However, if problems are detected with installed components, the system may initiate a beep code. Blinking Green The system is in a Standby ACPI state. Off The system power is off.
