New first build problem

[fredo]

Intel Core 2 DUO E6300 "LGA775 Allendale" 1.86GHz (1066FSB) - Retail

MB-064-GI Gigabyte GA_945PL_S3 (Socket 775) PCI-Express DDR2 Motherboard

GeIL 1GB (2x512MB) PC5300 667MHz Value DDR2 Dual Channel Kit

Samsung SpinPoint P SP2504C 250GB SATA-II 8MB Cache - OEM

NEC ND3550 16x16 DVD±RW Dual Layer ReWriter (Silver) - OEM

Asus TA-212 Series Midi Tower (Silver) - 360W PSU

BFG 3DFuzion GeForce 7600 GT 256MB GDDR3 TV-Out/DVI (PCI-Express) - Retail

My cpu fan stops spinning within a few minutes of windows loading. It works most of the time in the bios except when you restart it sometimes isn't moving. Also my cpu clock speed is 1.4GHz in the bios and the system window but 1.2Ghz in Everest when it should be 1.86GHz.

I looked at Speedfan as I thought it might be the PSU and it gave the following results:
Vcore1 1.18 - 1.23
Vcore2 1.84
+3.3 1.31
+5 4.92
+12 0 or 0.51 depending on what mood it is in.
-12 -16.97
-5 5.13
+5 5.13
Vbat 4.08
Speedfan also reads one of the temperature readings as -55°C and the cpu fan as 100000 RPM occasionally.

So do you think it is the PSU or could it be something else?
Thank you for your time.

Thanks for your reply. What PSU do you recommend? I was thinking of getting the Seasonic S12 430W Silent ATX2.0 Power Supply.

Just to update you, I reinstalled the drivers that came with the motherboard and the cpu fan seems to work now. The utility that came with the motherboard works now and the voltages seem normal. The only thing wrong with it now is that the cpu speed is still under what is should be, but I shall try to increase that.

Thanks again for your help.
