Serious problem with a new build...

Okay. I need help.

Recently purchased a load of bits to build my computer. They are:

Asus Striker II Extreme motherboard
Intel Core 2 Duo E8400 CPU
OCZ 2GB DDR3 1333Mhz RAM
Corsair TX750 PSU
LG BluRay + HD-DVD ROM drive
WD Raptor 150GB hard drive

And I'm using an old GeForce 5200 PCI graphics card while I decide what new GPU to buy.

My problem is that the computer freezes, powers down, and crashes randomly. First of all I tried installing Windows XP Pro (32bit) onto my new hard drive. It kept freezing during the "Installing Devices" stage but eventually made it through (I've no idea what changed). Then it would shut off instead of restarting during the installation. Then, once I managed to actually get into XP, it would hang or power off whenever I tried to touch my DVD drive.

Now, I didn't want to install Vista (Home Premium x64) until I got my new graphics card, but I thought it might be an incompatibility issue with XP, so I gave it a shot. But nope. As soon as the Vista installation gets out of the DOS-esque menus and onto the pretty backgrounded section it just hung. Every single time. I couldn't get any further.

So I tried XP again. With different hard drives (IDE), by removing everything from the computer that wasn't essential, by changing the RAM from dual channel to 2x single channel. Ran a few repetitions of Memtest, no errors reported. CPU doesn't go much higher than 50C. Nothing seemed to work.

The only interesting hint I did come across was that once I had installed XP and restarted the machine, it would hang or shut off at the loading screen (before the Welcome screen pops up). Upon restarting after the crash, if I select "Safe mode" it works fine. It's weird.

The things that have remained constant throughout my little testing process are the motherboard, CPU, RAM, graphics card and PSU. Unfortunately I have no way of testing any of these components on a different machine as the only other computers I have access too are 8+ years old or laptops. And like I said, the RAM showed no errors on Memtest.

If anyone has any ideas on what the problem could be, please let me know. I'm pulling my hair out here. I'm not sure what to try next.
 
got all the cables connected? the 4 or 8 pin one by the cpu and the extra one on the gfx card?(you probably have but it may be worth double checking :) )
 
Is the BIOS set to 'PCI' as the main graphics slot?

If it's set to the standard PCI-E and then having to switch to PCI everytime, that could possibly cause a problem?
 
All cables are connected.

From the power supply:
24-pin ATX cable to motherboard
8-pin EPS12V cable to motherboard
2x SATA connectors to DVD and HDD (Tried swapping connectors/cables, still no dice)
GPU is PCI-bus powered (Not PCIE)

From/to motherboard:
2x SATA to DVD and HDD (Again, tried different cables and connectors)
Front panel connectors (2x USB, 1x Firewire, power switch, power LED, HDD LED, reset switch)
4x fans (2x Noctua NFB9 + 1x Noctua S12-800 + 1x stock E8400 fan)

Might have missed something, so let me know if you notice any ommissions.

Also, the BIOS is set to PCI for the default GPU. Even tried setting it to PCIE to see if that made any difference, but no.

And since I have it handy, I may aswell post the rest of my voltages in case it matters at all:

Vcore Voltage - 1.26V
CPU PLL Voltage - 1.50-1.52V
CPU VTT Voltage - 1.10-1.12V
Memory Voltage - 1.82-1.84V
NB Core Voltage - 1.29-1.31V
SB Core Voltage - 1.48-1.50V
DDR3 Termination Voltage - 0.80-0.81V
3.3V Voltage - 3.29V
5V Voltage - 5.02-5.05V
12V Voltage - 11.96V
 
maybe a bit over the top but if you have no access to a spare gfx,ram or psu
consider getting some second hand gear to test then selling it on if it is of no use to you?
i would try the gfx card first then the psu then mem/mobo
Have you tried building the system out of the case?.possibly shorting on something
just a few more thoughts for you to consider :)
 
Just tried it outside the case. Still happening.

I think you guys are right about trying a different graphics card. Hopefully I'll have someone at working bringing one in tomorrow for me to try. If not I'll have to buy one, though it'll probably be local as I want to get it up and running asap.

If it's not that and it's not the PSU, I'm pretty stuffed as DDR3 and DDR3 motherboards are too damn expensive.
