PC wont stay on.

Wasn't sure where to put this.


I just built a gaming PC and when I power it up everything runs smoothly for about 30 Seconds and then it just Shuts down. My LCD Poster says INIT ROM when it shuts down. I've tried using only one RAM and unplugging the HDD. I'm stuck now and have no idea what else to try it doesn't stay on long enough for me to do anything Software or Bios wise. Any help would be awesome I just don't know what to try or check.

I haven't been able to do ANYTHING it just gets as far as the asus motherboard screen Press "delete" to goto setup. then no matter what I do after it will eventually shut down sometimes it stays on longer then other times.

I don't think it's the PSU theres still lights on after it shuts down.( if that doesn't necessarily mean anything how would I go about testing it for shorts?)

Should it beep right as it starts up? because there is no beep.

I tried Un-hooking the HDD and Optical drives, clearing CMOS, no luck there either.

I tried loosening the screws mounting the MOBO that didn't help.

All Connections seem fine.

I really Appreciate the help this is my first time building a PC, I've updated and replaced alot in computers but never built one until now. I figured there would be some tweaking at some point so I was prepared for this more or less. I just hope it's not a hardware failure I would like to avoid shipping back any parts if possible.

Thank you for the Help.

"init rom,,, no beeps" sounds like either corrupted bios,or system not seeing main memory,are you certain that all of your parts are compatible with your selected mobo,especially your ram and cpu,did you make all the required power connections to your mobo,and check that everything is firmly seated/attached....

Check your power connections to your video card, you need to have to 2 PCIE power cables plugged into it.

Put all of RAM modules back in (make sure their installed correctly, certain banks are reserved for dual channel RAM, consult your mobo manual)
Go ahead and press delete when you boot your system.

You will need to check several things.
-Check your CPU processing speed and voltage to see if it is correct.
-Check you ram timings and voltage to see if their accurate (check corsair's webpage for ram timings and voltage)
-Check to see if your CPU temperature is too high(anything above 60C should be cause for concern)
-Make sure all of your hard drives are recognized
-Disable that stupid ass ASUS boot logo before you exit. This will enable to view errors if they arise as the system runs through POST.

^^Bios default would be 1,8V for the memory (jedec standard), some sticks with fancy timings will need more than that to operate properly.

There have been plenty of issues with systems not booting up properly the first time when using overclocker-friendly memory that requires more voltage than the bios default settings provide
