I bought a new mother board, with new video card, and memory. When i start the computer nothing comes?

on the screen and computer shuts off sometimes after 5 seconds whats wrong|||Needs more more information to make a 100% accurate solution.

But here are some guesses.



1. Do you have a heatsink on your processor (usually metal fins with a fan attached) If you don't the motherboard will beep loudly at you on bootup after about 5 sec and shutdown (will only beep if the MoBo has a speaker.)



2. Your memory may not be compatible speed with your board. Be sure to read the specifications on the MoBo and see if your memory is compatible. (example: you may have PC4200 sticks (usually the cheapest) and your board may only support PC5400 sicks, its all in the reading)



3. There could be other compatibility issues. If thats the case, i need more info to tell you whats up.|||Its possible that your power supply isn't strong enough. Hard to tell based on this information. Please post system specs.
