If it does not start all the time, it is not stable.
What kind of PSU?
When you read the "can't boot" sticky, did you just read it or did you do all the steps?
Yep. 4 Pin connector is connected, no extra standoffs / none touching board in the wrong place, Video card is integrated until i get an adapter for my PCI-E card, I only have one stick of ram (OCZ 2gb), CPU is installed properly, i reseated the heatsink and the past 2 boots have succesfully passed POST the first time, I'll update if it's solved. (Edit: Not solved)
All plugs are connected properly as to how the manual describes and have reset CMOS.
When the system does not sucessfully boot, there are no beeps, no video goes on the screen, though the hdd works, dvd drive works, mobo light is on, all LED's are on, usb devices seem powered on.
When it does boot properly, there is one short beep and everything is fine.
Also, the PSU is just a 460w ($30) PSU that came bundled with my case.
