I Need Help, My computer started randomly crashing last month...

I troubleshooted the PS, RAM, and HD every thing worked in different machines. Eventually it wouldn't even power on.

So I ended up sending my mother board back to ASUS, and just got a new one back today. I put everything back together and it still wont do anything when I try and turn it on. After about 2 hours of trying different power supplies and RAM and power switches, I decided to remove the MB from the case and build it bare parts.

On the floor with just a mother board, power supply, Ram, CPU and Video it powers up. How can a case that worked for a year make a PC randomly power off and then ultimately make it dead as a door nail? Is it really the case, or am I overlooking something?

Here is the NewEgg item# and link: N82E16811144101 http://www.newegg.com/Product/Product.aspx?Item=N82E16811144101
 
try it in the case again but don't use the cases power button to start it up, maybe you have a bad power or reset switch.
 
You are not connecting something correctly (when it is inside the case). It may be a case issue. A similar happened to me last week when I replaced a HD, but it was the PSU which decided to die right when I changed the HD. Some things are too hard to believe, but they happen.
 
Also this is pretty simple but make sure all your brass standoffs are on and secure.

Could be that you might have missed one.

If this is the case put it back in the case and tough the + and - sides of the MoBo power pins with a metal piece, something like your key or maybe even a flat head.

That should at least give you a clue what is up.

Hope this helps.

Well normally I would just assume that I hooked something up wrong, but I built it myself from scratch and it worked great for a year before it started randomly crashing. Could a case fan have a short in it that would cause it to go dead? For clarification... the MB has a good power LED that lights up when power is connected regardless if its turned on or not. When the board is in the case, it gets no power good signal.

This indicates the power is "cut-off" at the PSU itself. PSUs are equipped with some protective mechanisms, such as "overload" cut-off. Did you try just mounting the MB in the sace WITHOUT connecting FP (ON/OFF and Reset) connectors? Also, try without case fans for a moment.
 
I'm guessing something in the case is shorting the system out.
 
Well, it ended up being the USB cable/ports in the front of the case that was shorting out the board. It powers up now, but got a new problem... now during POST it errors out (1 long 2 short). So I think the short might of damaged the video on the board.
 
Can someone confirm for me that 1 long 2 short beeps during post is a video error ???
