A recent lightening strike fried my comuter so I sent the motherboard back to the manufacturer to fix it. After receiving it back, I put in the new cpu, memory, hard drive, video card etc... and my original psu. The comuter fires up and I can access windows and other programs. All connections in the psu are working but the fan is not, when I put my hand in the back of the case, I don't feel any air movement. Do you think this psu is partially damaged? or should I not worry about fan? If I send it back to the company and If they don't find any error they will charge me 25 dollars and send back the same psu.
