I just built a new system last week and everything went smooth, last night I was playing WoW when all of a sudden my system shut down without warning and now it won't turn on at all. If I reset the CMOS or pull the power and plug it back in when I press the power button the lights and fans "flash" on and then the system goes dead again.
System has ran fine since it was built last week and no new hardware was added since then.
CPU - i5 750
Motherboard (model number) ASRock P55 Extreme
RAM (Model number, speed, timings, voltage) AData Gaming Series 2x2gb 1600
CPU cooler (stock or not, model if applicable) stock
Video Card (model number) Sapphire 5770 HD
Power Supply (model number, or company and wattage at least) Sunbeam 680W Modular
Hard drive(s) WD Black 750g 32mb
Operating System Win7 ultimate x64
Case (for cooling issues) Cooler Master Elite 310 w/1 120mm fan
Steps I've taken so far.
1. Removed everything but the CPU and tried to boot. Reinstalled each device 1 by 1 and system still won't post.
2. Removed motherboard from case and set on box, still won't post.
3. Removed both sticks of ram and tried each by themselves, still won't post.
4. Brought PSU to work and plugged it into a Dell in my office and it booted up fine.
When the power supply is connected, I do get my Power/Reset and Dr CMos buttons lighting on the mobo.
I'm leaning towards it being a bad motherboard? This is my first build in about 4-5 years and it's my first ever Intel build, but I have built quite a few AMD systems a few years ago and am pretty familiar with troubleshooting. Unfortunately I have 0 spare parts laying around like I used to.
