I bought a new computer and I'm almost ready to send it back to the shop. Here are the specs:
- Motherboard: Asus Crossfair IV Formula
- Processor: AMD Phenom II X6 1100T Black Edition
- RAM: 4 x 4GB CL9 1333Mhz
- Graphics Card: Sapphire Radeon HD 6970
- Hard Drive: Western Digital Caviar Blue 500GB
- Power Supply: Corsair Enthusiast TX850
At this moment (after trying many different things) the motherboard sits outside the case (nothing connected to the case), on a carton board. Connected to the motherboard is the 24 pin power cable, the 12v power cable, the processor, the graphic card, one RAM module, the hard drive and the keyboard. When turning it on (this motherboard has a built in power button) the screen displays POST and I press DEL to enter BIOS set up, then I touch absolutely nothing else (I barely breathe) and after 5~15 seconds it powers off by itself. In a few occasions it seems to be trying to power on again (the fans go on and a few leds blink) but it doesn't succeed.
I went to the Asus Power Calculator and my PSU should be more than enough.
Sometimes it doesn't even reach BIOS (it displays the logo and powers down).
Thinking it could be a heating problem I turned off the PSU, waited 5 minutes and brought my desktop fan and pointed it to the motherboard, tried again and no change.
Any idea what could it be or what can I do?
