    I have a new power supply, Antec EA 650. I've checked the outputs of the PS with a Thermaltake (Dr. Power) tester and it shows everything is good. What's next?

    I have checked the PS with a Thermaltake tester and it checks out.

    I am using the M/B as is. Nothing installed in any slots at all. Using onboard video and sound. This is a new custom built system. Everything was purchased separately from different vendors, but new. Have OCZ PC2 8500 memory installed (matched pair).

  • jer_erwin Jul 31, 2009

    I have reset the CMOS and checked all connections. Still no beeps!!

  • jer_erwin Aug 06, 2009

    Thanks, it was the memory and the ASUS M/B system DOES NOT beep for any reason according to another technical source that builds ASUS computers. I purchased some single sided memory to test (it was cheaper). I put one in and got it to boot up (finally). The manual wasn't very well written in describing the correct slot location when using matched DD/SS pairs. I tested all the memory individually in each slot and bank. Each tested well separately with no errors, but would fail the LRAND when both matched pairs were tested in the same channel. If I put one in the first slot of each channel they will work perfectly with no LRAND errors. This is a very picky board when it comes to memory type and manufacturer, so beware! Thanks for your help.

This could be any number of things.

1. Make sure the power supply is correctly hooked up, including the P4 +12v connector (usually next to the CPU, it's a foursquare connector).
2. Make sure the CPU is installed correctly, thermal paste is applied, and the heatsink and fan are installed and plugged in.
3. Make sure the memory is reseated and installed in the correct slots.
4. Make sure the power switch is hooked up to the correct headers on the motherboard.
5. Remove all acceossories except memory, cpu, fan, and video and see if it will turn on and post.

Please report your findings back here. Thanks.

Hi there,

Is your computer previously working? Did you added external harwares (sound card, video card, etc..)? If you are using an external video card, first thing you can do is transfer your your monitor to the built in video processor. If you are already using the built in video card, try to inspect/check your hardware cables for any loose connection. And also if all looks fine, try to reset the CMOS battery. If these doesn't show any sign of improment, please let us know.


Regards,

The board will not turn on


If the board has a power led then check that is lit.

The first power on self-test (POST) will beep when complete or give you beep codes if there is a detected failure.

If you have a good power supply (+5 volts and 12 volts) and a lit power led on the board and there is no POST beeps at all then that generally indicates a video problem.

Diagnostic Indicator


Beep codes and power LED status are pre-post errors. Usually beep codes indicate a problem with a memory module. Power LED is solid green for normal operation. Solid or blinking Amber color power LED indicates a power distribution problem.

Dell Optiplex GX260 Tower flashing yellow power button


Hi

Power up the Optiplex GX260 and check the QUAD Pack Diagnostics LEDs (located at the back). Compare the LED pattern to http://support.dell.com/support/edocs/systems/opgx260/en/ug/solvprob.htm#1167139 for more info.

Ideally, to troubleshoot and resolve the issues, try removing all PCI devices, disconnect all external devices/peripherals including keyboard and mouse. You may leave the Monitor connected. Power up the PC and check for successful Power On Self Test (POST). If POST completes (generally fails on "Keyboard not present"), shutdown, connect keyboard and try POST again.

If all goes well, install PCI devices one at a time and test successful POST. This will help identity a failing device.
If issue persists, after removing all devices, remove the CMOS battery for about 90 seconds and try POST again. If same, remove all DIMMs (Memory) and check for beep codes. Compare beep pattern to http://support.dell.com/support/edocs/systems/opgx260/en/ug/solvprob.htm#1176760.
NB: Ensure to remove power lead and press power button briefly to use up flea power before working in the system.

If the system beeps, it suggests that the CPU and systemboard are "likely" fine. Install one DIMM at a time and test successful POST. If there no beeps then the systemboard and/or CU is/are at fault.

Mike

A7V8X NOTHING HAPPENING,


When a power supply goes out the way yours did, it's going to fry the MB 99% of the time. So you're going to need a new MB. It's possible that you CPU is ok, but that could also go too. I would replace the MB first, then the CPU if that doesn't work.
