I bought the components to build a fast system, but it randomly keeps rebooting. Specifications:

Asus p5w dh deluxe mobo (last bios flashed)
Asus Videokaart PCI-e GeForce 7900GTX 512MB DDR3
Kingston 2x1gb ECC DDR2 SDRAM PC5300 CL5.0 (kvr667d2e5k2)
Intel Core 2 Duo E6600 2.40GHz FSB1066 4MB Cpu
Zalman Processor Koeler CNPS9500-AT S775
PSU: Cooler Master iGreen 500W SLI/EPS

extra PCI cards installed:
- Hauppauge PVR 150MCE
- Skystar 2

It is not a software issue because it sometimes restarts when I am in BIOS!

I am wasting my time for over two weeks now... :(

I used memtest86+. It took 1/2 hour to complete the test, but it reported no errors.

When I entered the configuration of the tool, the computer hangs.
The tool checked without ECC, but this memory supports ECC. I wanted to test ECC too.

My PSU
RS-500-ASAA
AC INPUT 115V / 230V 10A / 5A 60 / 50Hz
DC OUTPUT +3.3V +5V +12V1 +12V2 +12V3 -12V 5Vsb
PEAK 25A 20A 19.5A 19.5A 19A 0.8A 3.5A
CONTINUITY 20A 15A 14A 13A 6A 0.5A 3.0A
141W 396W 6W 15W
MAX. POWER
500W (Continuous)

As I am on my work now, I cannot check the voltages as mentioned in the bios.

Regarding the tempurature: I noticed nothing special. I use the TJ05-ST from silverstone to guard the temps. I also double checked in the bios to be sure of the temps.

I didn't play with voltages till now, what should I know about the voltages used by CPU and memory?

Could there be some inconsistence between the FSB1066 and the memory running on 667Mhz?

The problem is solved. You will never believe this.

********** SOLUTION **********
I have a UPS with two PCI-e connectors. One is 6amp. the other 17amp.
I connected the 7900GTX card to the connector with 6 amp.

After reading a lot and a lot and a lot I came to a suggestion of someone who says that the newer graphic cards needs much more amp. then the normal ones.

I checked on internet and my card in facts need minimal 22 amp. Because I only have a maximum of 17amp. on the 12volt cable, I connected the graphic card to this connector, and ....

No more random reboots.

I hope this solution will help others who have the same kind of problems.

Thanks everyone for the input.

How do you know about the 11A my graphic card needs? I checked the internet and I only could find a lot of topic speaking about 22A.

Where can I find something about my motherboard also supplying 5A?

And are the Cooler Master PSU not of a good quality? Then I am of luck that on the 3rd rail only the P5 is feeded.

Thanks in advance.

Now al is working, at least I know, for the moment being, I don't need to buy a new PSU. (I hope)
