Computer shuts down/cpu fan stopps spinning

[holyhitman]

Hello to all.

I have a problem.

My PC shuts down at random intervals, from 1 second to 10 seconds. Also, my cpu fan sometimes will not start spinning until 3-5 seconds after i push the power button; sometimes it tries to spin but it cannot.

I have just gotten a new power supply because my other one died. I have purchased another power supply while i was waiting for the replacement and it worked fine until i put the new one Sigma sent me.

So I am trying to figure out what the problem is. I am not sure if it is the power supply or the fan. I returned the power supply that I temporarily had, so I cannot try to test it.

My specs:

ARCTIC COOLING Freezer 7 Pro 92mm CPU Cooler
SIGMA SHARK SP-635 635W ATX12V V2.01 SLI Ready Power Supply
Intel Core 2 Duo E8500 Wolfdale 3.16GHz LGA 775 65W Dual-Core Processor Model BX80570E8500
EVGA 896-P3-1260-AR GeForce GTX 260 896MB 448-bit GDDR3 PCI Express 2.0 x16 HDCP Ready SLI Supported Video Card
G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) Dual Channel Kit Desktop Memory Model F2-8500CL5D-4GBPK
GIGABYTE GA-EP45-UD3P LGA 775 Intel P45 ATX Intel Motherboard


Thank you for your help.

Hi, if it worked fine I would take the P/S back and get them to test it.
