How Do I Run A Power On Self Test, (POST)?
98779
A power on self test is generally run each time you power on. Some motherboards allow you to quickstart bypassing some tests, you can change this in the bios.

check your power supply and makes sure it is connected correctly, and make sure the power supply isnt a dud

Plug all your computer equipment into a surge protective power bar...although very rare...it is known to happen\n\nBut to keep your system running should the power go out...install a generator to your power fuse panel.

In control panel have a look inside the power manager settings.\n\nYou should be able to configure different power usage settings (including screen brightness) for when you are attached to the mains and when you are running on batteries.\n\n///

Ok, as I understand it doesnt boot from the first attempt - a.k.a. Motherboard doesnt "POST". And when you reset the power it loads up.\n\nAll I can think of is that your battery on the motherboard ran out, and when you power up and keep it on, it gets enough charge to send a POST signal on the rebound.\n\nTry replacing your "CMOS Battery" on the mother board. It's usually a ~5$ nickel sized battery, which is "nested" in a socket on the motherboard. Best way to test it, is to take it out, and put it in ur mouth - if u dont feel much buzz - its dead :P\n Dont worry testing batteries that way is safe, and the only reliable way, when the Multimeter is not available :)

the tones are a POST code power on self test, you need to go to the website and see what the codes mean, if you can remove your power supply i would have that checked as that causes most problems or it may not be powerful enough for your system should be a minimum of 400 watts, if you have a good video card 500 watts, you can download memtest 86 to test your memory, but memory rarely fails, intel processors rarely fail. the big failures are power supplies video cards and hard drives.

set to 115watt? u mean volt? .. dont mess with that switch lol ... anyway ... make sure its the correct psu for the board 24 pin or watever ... if you have a dedicated graphics card make sure power is plugged in to that if it requires it .. and also make sure there is no other "floppy" or another type connector from the psu that needs to be plugged into some spot on the board... backtrack and take everything off the board but the videocard/proc/and mem ... see if it will boot to bios settup (del or f1) ... load bios defaults if it does .. then go from there ...
