I INSTALLED A 500W POWER SUPPLY AND A NVIDIA 8800GT OC. IT WORKED GREAT FOR THE FIRST WEEK THEN MY PC SLOWED DOWN. I CONTACTED BFG, GPU TEMP GOOD.SEVERAL EMAILS LATER , THROUGH PC WIZARD 2008 PROGRAM, MY VOLTAGES SEEM LOW TO BFG TECH. HE SAID TO GO TO MY BIOS MENU AND SEE IF IT SAID THE SAME THING AS PC WIZARD.BIOS ADVANCED MENU OPTIONS, UNDER POWER , ONLY SAYS CPU FAN SPEED AND TEMP, NOT VOLTS.I AM LOOKING FOR A VOLT SCANNER TO COMPARE OR ANY SUGGESTIONS TO MY PROBLEM.

I AM NOT HAVING ANY VOLTAGE SWINGS. IT ALWAYS SAYS 2.04 ON 3.3 , 5 ,CPU. 6.55 ON 12, 4.08 DIMM. + 12V x 2 SUPPORTS 34 COMBINED. 8800GT REQUIRES 425 PSU SO I THOUGHT 500W WOULD BE ENOUGH BUT MAYBE NOT. E6700 CORE DUO,P965,ASUS,LGA 775. 4GB BALISTIX TRACER, ORIGINAL FANS, 1 8800GT OC FACTORY CLOCK. SO IM GUESSING I NEED MORE WATT PSU ?

The 8800GT is a 110 watter. Your OC version probably draws a few watts more. So, the card itself draws almost 10 amps on the +12V rail. If your PSU has 18 amps on +12V1, it should have no problem powering the card BUT if only 15 amps or less, it might struggle because other 12V devices will share the power on that rail. +12V2 powers the processor voltage regulator circuitry on the mobo.
Try Speedfan also to check your voltages.

Use the chart to track fluctuations on the +12V rail. You should be more concerned with the voltage swings rather than actual value. Voltage calibrations for various motherboard sensors differ.

You need at least 600W power supply MINIMUM to operate a 8800 card, ESPECIALLY IF YOU'RE OVERCLOCKING because that requires two things: extra power, and extra cooling. 500W will simply not fly. If your computer motherboard supports SLI (dual PCI Express x16 slots for dual video cards running as one), 600W is a minimum requirement (emphasis on minimum), and higher voltage ones are still recommended from 800W to a 1 megawatt.
I strongly recommend getting a higher wattage power supply. You do run the risk of damaging your components at low voltage if your PC does brown out (forced shutdown from low voltage).

may be it is not right for the computer or the pc voltage has a problem
