Hi
I built my computer over a year ago, it's a custom gaming machine and it worked fine with minimal problems the whole time I have had it.

Yesterday it kept freezing for no apparent reason about 5 time. It is not caused by a specific action or program as it happened at random times even sometimes when it was idle. The only solution was to restart. I didn't think much of it as a similar thing had happened before to me when graphics drivers were not properly installed. I updated my graphics drivers just incase it was a repeat of the same problem.

I turned on my computer today and it has totally failed. It will not boot even to the BIOS and wont POST. When I press the power button the lights and fans all start up and everything sounds like it should (Diskdrive starting, hard drive spinning) except there is nothing on the screen.
I have spend all day trying to fix it to no avail. I have took out all sticks of RAM and tested them in all the RAM slots individually, the DRAM LED doesn't stay on (showing that they work according to my motherboard manual). I have removed my sound card and graphics card, checked connections and tried different screens and ports. All that happens is that the Boot Device LED stays red along with the VGA LED. I have even reset the BIOS using the ASUS bios flashback function but no change. I have taken out the CMOS battery and left it then put it back in and have switched jumpers on the board that reset it.

I have made no hardware changes in ages. I have just came back from holiday so my PC has not been touched in awhile, don't know if this makes a difference.

Finally, to help diagnose the problem further I attached a speaker to the motherboard and shortly after boot up I hear 1 long beep then 3 short beeps then after that 1 long beep and 5 short beeps.

I have no idea what to do next, please help.

Solution
Break, no, 'fail' yes. Every component has a life-span in hrs. or power cycles. Eventually they go. From what you have said, your system should have lasted longer. Your PSU is a low-performance model and can fail in this way at this age if the main capacitors have been 'hammered' by heavy gaming.

I'm going to try and test my graphics card in my friends PC and test his in mine soon. I don't understand how it could be broken, I have done nothing to it and have not seen anything that may of caused damage to it. Can components break like this out of the blue for no reason?
