PSU, Memory, CPU, Mainboard can all cause these symptoms. Would start with the PSU!

State the make and model of your brand name system.
The specific brand name system model is usually on a label on the outside of the case somewhere, or it can be determined by going to the brand name's web site.

If you HAVE NOT changed which ram you have installed since the computer last worked fine, or in any case....

See response 2 in this - try cleaning the contacts on the ram modules, and making sure the modules are properly seated:

For a laptop, you must remove both its main battery and AC adapter before you do that.

See your Owner's or User's manual for your brand name model, or the mboard manual for your model if you have a generic desktop system, if you need more info about how to properly remove and install the ram modules.

If you HAVE changed which ram you have installed since the computer last worked fine....

Ram that works in another mboard , or any ram you buy or have lying around, may not work properly, or sometimes, not at all - even if it physically fits and is the right overall type (e.g. SDram, DDR, DDR2, etc.; PCxxxx, xxx mhz) for your mboard. In the worst cases of incompatibilty your mboard WILL NOT BOOT all the way with it installed, and the mboard may not even beep - the ram has to be compatible with the mboard's main chipset, or in the case of recent mboards, compatible with the memory controller built into the cpu.

The same applies for testing your ram in another mboard - the ram must be compatible with the other mboard - if it isn't, any results of testing the ram on the other mboard cannot be relied upon to be valid.

If you still have the ram that was installed when the system worked fine, try installing just that ram.

See response 5 in this for some info about ram compatibilty, and some places where you can find out what will work in your mboard for sure:

You may have a problem with your main battery, or there may be something else wrong and it's not being charged properly.
