Confirm that the black on/off switch on the PSU is set to 1 and not 0. Remove your side panel and reseat the ATX power connections to your motherboard by unplugging them and then plugging them back in. Do this for the 20/24 connection and the 4 pin connection. (Remove the AC power cord from the PSU while you are doing this so an stored electrical charge can clear from the system.) Confirm the voltage on your PSU is set to 115 and not 230. Try clearing your bios by using the JMOS jumper or removing the CMOS battery. Remove your memory and POST the system without it and see if you get 1 long beep. If not it may be an issue with the motherboard or CPU. If so, try putting the memory back in one stick at a time and boot it up every time you add a stick to see if one of them is bad. As u told here i have checked all option then also it is not giving beap. Pls help.... Hi Neil, If another shop checked out the PSU already I would try a few of the following things.

Are you getting any beep codes from the system when you start it? Do you experience the same issues when you perform and isolated POST test? Was the system working before and now will not POST or is it one you just assembled? Please provide additional details on the issue. Thanks.

I have found the easiest way to turn the system off (when POST testing, etc.) is by flipping the black switch on the back of the PSU. You can use the jumpers to do this also but if you are in Windows you would need to hold the screwdriver in place a few seconds for it to receive the power off signal.

When you switch it on with the screwdriver do you only need to tap the connections or do you have to hold it on there to keep the switch closed? Secondly after the test do I have to tap them again to turn it off, just remove the screwdriver to break the connection or just switch it off at the power supply??? Thanks!

One small thing...it a heat sink, not a heat sync. It doesn't sync(hronize) anything - it dissipates heat. Otherwise, top notch guide - kudos!! Great guide – thanks!

From this point you should start seeing boot up information displayed on the screen. If you hear this beep but you are not seeing the information being displayed on the screen this can most commonly be a result of a failed display port. (Onboard or Video Card.) If you are running onboard video see if you can get a video card to test the system with. If you are using a video card see if you can test the system with on board video. If not, swap the current video card for another one and see if that makes a difference. Since most people do not work in tech centers if you need a part to test the system with you can always purchase one locally, and make a note of the stores return policy in case the replacement part does not resolve your issue.
