my pc is a dell duo core, with meory more than 700 MB, but it takes long to load the OS(windows xp) and it is also slow, could it be a harddisk problem?

For optiplex GX-520s the power supply fan is usually the problem. It is a 70X15mm Usually ADDA DC brushless 12v .18A that stops spinning. Check thecapking website I will eventually start selling these fans as it seems to be happening to me a lot lately.

I had a problem with a GX520. According to the user it was happening once a week. When I looked at it I died with a minute. I had a hard time starting it. It had dust through out the box. I blew the dust out of the the computer and power supply. It stopped..

If you are unable to stop the computer from going to sleep or hibernating, which is rather strange, then you may want to look at disabling power management in the BIOS. I would contact Dell technical support on this one, if you have not already done so.

Cagemonk and Jmello i have a simular issue with our GX520. Its a power supply issue. The power LED should blink an amber light. Where are you guys located? I am trying to get the GX520 problem fixed but dell thinks its our power. So can you please post where you are from and if your still having this problem. Thanks. FYI I am in Southern California.

You might be confusing your Power LED being Yellow as your PC being in a sleep mode (like a Laptop). When actually it’s telling you have a problem.

Check this link for LED Status Codes.

I have had several Dell OptiPlex power down to a Steady Yellow LED and had to have their motherboards and CPU replaced.

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.
