Power problem with my new system??

I've finally built my new system with the following specs:

AMD Athlon64 3200 (Winchester) with TT Silent Boost K8 HSF
Asrock Dual SATAII mobo
1gb (2x512mb) Geil Ram with blue heat spreaders
Connect 3D X800GTO
Audigy LS
MSI DVD ROM
LG 4163 DVDRW
Maxtor Diamondmax 8 (40GB )
Enermax EG465AX-VE
Coolermaster Cavalier 3
running on Windows XP x64 Evaluation edition


Well it has generally been running good although sometimes when I am starting up say Farcry it doesn't load up properly, then once or twice the PC will restart itself after running an app.
In gaming such as Farcry or Doom3 it can crash which is expected.

However, I installed Speedfan to check the system temps and I noticed the power (v) figures looked wrong especially the - (minus) values. What do you think? Any help or suggestions would be appreciated
