new rig problem, urgent please help

Posted on 2008-06-25

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

Reset the CMOS by using the jumper on the motherboard, in case something changed in the BIOS that causes it to hang.  A failure in the onboard video can hang the whole system, but that will require a new motherboard to fix.  Try a different power supply that is at least as powerful as the current one.

Hi Callandor, tried reseting the jumper with no luck. I dont have a different compatible PSu at hand, I will take everything apart and put back together tomorow morning. Do you think that could be something with the CPU?

CPUs rarely have a problem with them.  Motherboards are far more common and exhibit symptoms similar to what a bad cpu would have.  The only trustworthy method to distinguish between them is to swap the part with a known good one.

from all the symptoms I came to a belief its the motherboard. going to RMA it today and get a new one. do you think it is worth to get the same one? I was considering the XFX 630i Geforce 7150 775 mATX as an alternative

Are you restricted to the mATX form factor?  I have been recommending the Gigabyte GA-EP35-DS3L for Core2 Duo processors as a good value.  Otherwise, the Asus or the XFX are good buys if integrated video is sufficient for your needs (not desirable for 3D gamers).

yeah I need mAtX board for this Antec case. Im going to send bak the Corsair ram too, it seems that they are very picky with those 4-4-4-12 timings, going to get a 2gb kit instead. I am looking for a mATX board with decent on board graphics and that are good for quads

How about this Intel G33 board?

Intel chipsets typically work extremely well with their cpus, and this one has gigabit and eSATA.  They are not good for those who want to overclock (which the Q6600 is good at), because they do not provide many options for tweaking speeds.
