have bought an hx750w corsair power supply 1 week ago all over the sudden unit started freezing, no blue screens or anything just freezes and needs a reset

System specs
dx58so
i7 970
3x2gb ddr3
2x500mb raid 0 7200rpm
2x4870 512 crossfire
and new psu
hx750w

was wondering if this voltage readings are normal?

Hardware monitor Andigilog aSC7621
Voltage 0 1.05 Volts [0x51] (+1.5V)
Voltage 1 0.90 Volts [0x4D] (CPU VCORE)
Voltage 2 3.18 Volts [0xB9] (ATX +3.3V)
Voltage 3 4.90 Volts [0xBC] (ATX +5V)
Voltage 4 11.81 Volts [0xBD] (ATX +12V)
Temperature 1 33°C (91°F) [0x21] (Zone 2)
Temperature 2 38°C (100°F) [0x26] (System)
Temperature 3 42°C (107°F) [0x2A] (CPU)
Fan 0 1865 RPM [0xB50] (CPU)

i know hardware monitor is not as accurate as a multimeter but its all i have right now
1.5v looks low, and same with the 12v, review of this power supply showed readings of 12.18

are these numbers normal or low?

As useful as those numbers might be they can still be off and I wouldn't use them as a method to determine if the PSU is failing or not. Any particular situation that is causing the system to freeze? 11.81 is about 1.6% below the nominal voltage which is still well within the acceptable range. 1.5V reading is probably not accurate. Test your memory with memtest and lets see if those results pass. your crossfire 4870 setup also puts a large strain on the system at full load (probably something in the vicinity of 350-400 W alone) so you could also try a gpu stress test and see if that causes the machine to crash.
