In cases like this, the event viewer will probably not say much, unless it is a consistent software problem. If it's hardware, just about anything could be running when the crash happens. The event viewer is great for software problems, not so great for hardware, unfortunately.

I had no idea that so many different things could cause this problem.
I owe all of you a big Thanks for your responses.
The pc is a Lenovo, purchased at Best Buy about six months ago.
I don't know what brand of PSU is inside but when I open the case I'll take a look.
I'm going to go and check out all the ideas that you folks have suggested and check back here when I finish.
Again, Thank You.
6 month PC old and no warranty from manufacturer or costumer service?
Usually waranty up to 3 years since date of purchase.
Find your guarantee coupon and see what is written there.
I worked on a computer one time that worked perfectly laying down but I stood it up it would shut down with a minute. I found the heatsink was loose.when the tower was stood up the heatsink would separated just enough that the processor would overheat.so check the heatsink you should not be able to move it with you hand, is the fan on the processor running? is there a ton of dust on the heatsink?? clean it with a can of compressed air or a small artist brush or blow it out with a straw.also check that the fan on the power supply is working.

Where there is dust if computers assembly just a few months ? And if the cooler was not in right place then it would permanently shut off and didnt work.

My house is very dusty, things get gunked-up quickly. Dust on components that generate heat, acts as a thermal blanket.
A *properly* installed heat-sink should have thermal paste between the bottom of the sink and the CPU chip. The CPU heats at different rates depending on load and ambient temperatures.
Web sites (like C-D) that run scripts can increase CPU load. The laptop I am using at this moment has a heat issue, the more C-D tabs I have open, the higher the load. Depending on the temperature in the house, this machine exhibits the symptoms that the OP describes when I am looking at C-D (and others). I resolved the issue temporarily by installing BHO that kills scripts (NoScript for FireFox), and allows me to selectively enable just the ones I want, and by throttling back the CPU.
Eventually I'll get around to unscrewing the 377 tiny screws that hold this thing together, clean the heat-sink and re-install with a new coat of thermal paste...some day...maybe...but right now it's just easier to keep the CPU throttled and kill the scripts.

You're problem sounds like a capacitor going bad on the motherboard. Since it's less than a year old, contact Lenovo for tech support. Back up your data as you most likely will have to ship it to a repair center.

Good point, a bad cap could do it.
In fact, that has been known to be a problem in the past- mobo manufacturers using different caps than the designers spec'd, in order to cut production costs.
