PSU Issues

by pvc_ - 2/9/08 11:50 AM

well, I have built myself a new pc and unfortunately the process has been more annoying and painful than I originally anticipated. The main problem I'm facing is that my pc crashes without any kind of warnings or errors a few minutes after its load. When I was first installing windows, it wouldn't even let me finish the installation and would randomly restart. So, a friend of mine suggested that the RAM could be bad and asked me to use different combinations of my 2 RAM modules and the 4 available slots. After disconnecting one of the RAM modules, the installation was completed and I was able to start windows, but still crashes randomly.
After doing all kinds of updates for different devices as well as windows I came across a program that came with the Motherboard called "I-Cool." This program basically allows you to manually determine how much CPU power you wanna get, so if I set it to anything less than %100, my computer will continue to work, but shortly after I change it to %100 power consumption and fan noise, the PC crashes again.
So, from this I have a feeling that my 650 Watts (SLI) PSU, is not generating enough power to run this system. I just wanted to know if this is a correct assumption or there is something else that I'm over looking. BTW, if I add the second RAM, it would crash again regardless of the power setting.

Here's my spec:
OS: Windows XP (SP2).
Motherbord: Gigabyte, S Series N650 SLI-DS4L
RAM: 2 PQI (1 GB) Turbo with heatspreader.
CPU: Core 2 QUAD Q6600
GPU: GeForce 8800 GTS (520 MB)
PSU: Antec 650 Watt, ATX 12V V2.2 & EPS12V (SLI Ready)
HDD: 320 GB Sata 1 Western Digital.
Case has 4 fans, but only 2 of them are running (2 X 90 mm)

***PS, one other thing I have to mention is that on the GPU box, for the PSU requirement, it is suggested to have a 600W PSU for Non-SLI, or 700W for SLI Power Supplies.
