I rarely have problems with stuff purchased in the USA. I buy all name brand here and it will often fail. What could be the reason. Products to fail me:

Ipod

Ipod Head Phones

Asus Motherboard

Asus Graphic Card

A second Asus Graphic Card

3 different Microsoft Mouses

Play Station 2

Heat?

Electrical Sockets delivering too much power?

Products here are really copies or have been refurbished? Why is it that so often here when you buy a product it looks like the box has been opened 55 times previously?

The good thing is that I have never had any problems using a warranty to get a new one.

Maybe it's the electrical system at your house/apartment? I've bought lots of things over the last couple of years and have had zero problems so far with any of it... PC, laptop, iPhone, dSLR camera, point and shoot camera...

I think it's a combination of heat/humidity, and a power system that frequently fluctuates. I would suggest that you invest in a UPS. That will at least level out the current to your computer a bit. That being said, I still had a motherboard die on me here after only a year of use, but I think it may have been a case of crappy capacitors.

I have to agree that these are factors. See a PC in action in a non aircon room at the height of the hot season and hear the poor single onboard fan running like a demon. In my latest PC I bought one of those Darth Vader gaming cases with 4 massive fans and I use it in an aircon room too.

I lost a hard drive to a power cut. Simply woudn't reboot. Learned my lesson there. I've got a UPS now which will at the very least let me shut the computer down safely if the power goes out.

Agreed.

Another factor is lightning strikes in the rainy season that send spikes down the line,

both electric and telephone!!

I am not sure how you can protect against this?

A UPS may help, but then the UPS gets fried, instead of the appliance it protects.

In the extreme this is what happened to my neighbour's electric meter.
