Firstly, I shall tell you all my setup. This is a new PC build to replace my old one.
Motherboard: P7P55D Deluxe [1.06G]
Processor: Intel Core i5 661 [3.33GHz]
RAM: Kingston DDR3 2x1GB [1333GHz - KVR1333D3N9K22G]
Graphics Card: Nvidia 8800GTS [640MB]
Power Supply Unit: OCZ (unsure of model AToW) [700Watt]
I hooked everything up, using bare minimum spec. and all worked perfectly first time (I also had a DVD+/-RW drive plugged in). It beeped a few times, but that was because I didn't have a mouse or keyboard plugged in yet. As I was reading the on-screen message that said a BIOS update is recommended, it processed to try and boot. Popped in a LiveCD of ubuntu and it booted up fine. I thought to myself - awesome! Connected a USB mouse and keyboard - and it was all working fine.
Played around in ubuntu for a bit and all was working perfectly. I then shut down the system, unplugged the power, and then started to connect my HDD's (note, it was already in the case and all front panel connectors for the PWR LED, etc were plugged in). Plugged the power back in and tried to boot, and it wouldn't progress through the POST. No beeps, no messages on-screen, nothing. Fan's were kicking in, system was powering up, but that was all. Looked at the motherboard, and it was stuck at the CPU level (the CPU LED stayed on).
I've tried everything to get it up and running, but nothing worked. Bare in mind I didn't flash the BIOS, I didn't change any settings, all I did was connected my HDD's. So I tried to eliminate the problems, slowly starting with just the motherboard, and then slowly going through parts in order of priority (CPU being first). Still nothing, spent 6 hours doing so and still nothing. Even tried clearing CMOS, removing the battery and power for several hours, nothing helped.
Any help would be mostly appreciated. I seriously don't know what to do now. I don't know what went wrong! It worked the first time! I made sure I was static free (using anti-static wristband connected to earth), and made sure I didn't touch any metal contacts, etc... all the usual procedures. I'm truly baffled how it would work one minute and not the other.
