I have just built a new PC for office use from the following parts:
ASUS P5E-VM HDMI iG35 Socket 775
Corsair 4GB (2x2GB) DDR2 800MHz/PC2-6400 XMS2 DHX Memory CL4(4-4-4-12)
Intel Core 2 Quad Q6600 Energy Efficient 95W edition Socket 775 (2.40GHz) G0 Stepping L2 8MB Cache OEM Processor
Antec 80PLUS® Certified EarthWatts 380W ATX12V v2.2 power supply
Hitachi 250GB T7K500 HDT725025VLA380 SATAII
Sony DRU-190S 20X DVD±RW DL & DVD-RAM Serial ATA
All this went into Antec NSK 3480 MATX Micro Tower and after I connected the last wires I pressed the power on button. I was so happy when the blue power LED around the power button went blue and the PC started humming so quietly. The first time it booted fine and the system saw all the components on the post screen.
So I went on to install Vista Business onto it. Vista was installed without a problem too, however after the last restart when all the files have been copied and extracted the PC froze prior to booting the OS. It froze on one of the BIOS post screens, without any information on it, just the logo. It stayed like that for about 20 minutes and then I attempted to restart it with the reset button - no luck, it didnt respond. Then I pressed and held the power button and it did not turn off the PC either, so I had to switch the I/O behind the power supply.
Since then the new rig does not want to work. When I power it on all the drives start spinning, the power LED on the motherboard goes green, fans work but apart from that there is no signal on the monitor and nothing at all comes up on it at any stage. Now even the ever so calming blue LED around the damn power button does not light up as it did originally.
My first assumtion was that its the ram, I know it is risky to put 4GB of ram into a 32 bit OS, but it worked previously on different systems for me so I dont know. I have tried booting with just 1 ram stick in different slots but no luck.
I have also tried disconecting everything from the motherboard(which by the way only included the USB/Firewire/HD Audio cables from the front panel) with only the DVD burner and HDD left in it. The monitor is connected to the onboard graphics port.
I am lost and confused, please help as I need this PC to work asap...
Thanks in advance
