+12v of 0.0v - Reading from speedfan need help plz!!


After opening speedfan I noticed this strange reading: my +12v is 0!
Need help plz. Recently I experienced crash in Far Cry and unstable performance in Oblivion. Far Cry crashed even at vCore 1.25v on stock speed. I used to OC to 2.8GHz but now I can't, not even 2.1GHz. I think my PSU has a problem.

I have E6300 B2 @ stock
OCZ Gold XTC PC2 6400
OCZ ModStream 450W 26A
Gigabyte GA-965P-DS3 rev 1.0
ATI Radeon X800 XL 256MB stock
Coolermaster Centurion 5
Thermaltake Big Typhoon
Arctic Silver 5
Seagate 250GB SATA 7200.10

  1. LMAO! SpeedFan says 0V and you believe it? Your system wouldn't be running at all if the power supply had any serious issues.
  2. What software can read PSU voltage?
  3. The PSU is connected to the motherboard, there are several sensors that detect the input voltage near the ATX connector. Unfortunately, most software that is supposed to take readings from those sensors uses the wrong reference values, or is automatically configured for the wrong controller chip.
