SOURCE: installing 2 sticks of 1 gb ram = DRAM error beeps

If the computer is working with one gb stick and not the other, try this:

Swap the sticks with the one that does work. If it works then its the memory card slot on the motherboard. If it doesn't boot up, then it's the memory stick.

SOURCE: Ram beeps codes encountered but ram not issue

it might be a bios problem but you might have the wrong ram modules so tell me first what ram does the mobo use and also what ram did you buy.

SOURCE: GA-8SIML will not post or boot. Removed all PCI


Firstly you check your RAM by use another RAM and then check it is working or not, after that if display is not coming then check your processor it is fitted properly or not if it have fitted and display is not coming then *********** board's winbond chip have been damaged.

Repair it from a techinician.

i seem the power supply gone bad, it is hard to say what is the problem actually, you need to check all of your devices(processor, ram, video card, motherboard and power supply) to some other system one by one for confirmation.

Carriage all the way to the left, constant beeping sound

The Mastertype 3 is the same machine as the Nakajima AE-710.
Check that the Print wheel is installed correctly.
Check the multi-wire flex harness underneath the carriage assembly...there may be broken wires.

My Dell 100L will not switch on and battery will not charge.

since the LED is orange it might be a ram issue. try to locate the memory modules in your computer then try to reseat them. or if you have 2 ram modules try to remove 1 first then try to turn on the laptop check if it will do the same thing. then try removing 2 ram modules check if it will beep. if no beeps ask for mobo replacement. if it has beeps take note of the beep codes.

No video from P4DMS-6GM, one long continuous repeating beep from speaker

For this motherboard, having a phoenix/award bios. first thing you should try is reset the bios. one long beep is due to video. If you are using onboard video, can you try using a pci video card to see if it boots up first? if you are using a video card already, try reseat or replace the video card.
