It sounds like either your power supply or your motherboard isfailing. The
easiest thing to check first is to replace the power supply with a known good one of adequate wattage. -- DaveW "jam rock" wrote in message ... like subject: when posting, the speaker goes "BEEEEB" and the power shuts off. then if I unplug the ac-power cord while powering up for maybe 10 times, it suddently boots ok. i'm not sure what exactly helps, anyway it helps being desperate..... i've had the problem before, but at dissapeared.

Here are some things to try:
0) Stuck key on keyboard? 1) If you have a voltmeter, check voltages at the motherboard power connector, or when it does boot, [Del) to BIOS and read voltages with hardware monitor or load ASUS PC Probe software to see voltages, remember voltages my be ok, but my have ripple (bad filter capacitor) that can not be seen without an oscilloscope, so as last resort replace PSU. 2) Pull out all PCI cards, and go to one memory DIMM (if you have more than one). 3) Eliminate things....If you have an old PCI video card, remove your AGP and try with PCI video card. 4) Re-seat your memory, reseat your Athlon CPU, check for loose jumpers, flip all dip switches several times, carefully setting them back. 5) with canned air blow off your motherboard, if metallic particle between pins you might make it worse by impacting it, best to remove mobo hold it on edge and tap it lightly (on workbench) on all 4 axis, then lightly blow with canned air, easy with the air on DIMM and PCI connectors....pins will start oscillating and break off. Please post your results to group so we can all share.

One more thing. The number of beeps have significance.
1 beep = normal continuous beep or repeating short beeps = power supply one long and one short = system board there are other codes , but I can't remember "Joe101" not valid@email wrote in message ...

... Problems with memory, PSU or CPU can cause the same symptoms. 1) The first thing to check is the memory, if the memory sticks are correctly installed and in good shape without errors, you may test your memory with : http://www.memtest86.com/ or http://www.docmemory.com/ 2) Look your CPU, is it overheated ? is the fan working correctly ? is it correctly settled into the socket ? 3) Is your PSU delivering the right power ? must be replaced ? do you encounter Random Shutdowns and Reboots without explanation ? |
