new pc crashes

[dazz075]

Hi all i am in some desperate need of help.I have a new pc which is only weeks old,and it keeps resatarting by itself-usually always when im away.Only yesterday i was burning a dvd and the pc shut down and restarted when i was only half way through burning.I
I dont know what the hell is going on.Ive updated video card drivers,and the bios.Nothing seems to be running hot as pc probe is saying everything is at good temperature.So i get these random restarts whic usually occur when im not there-but then yesterday it happened while i was burning.My system is:
Asus a8v deluxe +wifi that came with the board
amd 64 3200+
kingston 512mgx2
ati radeon 9600 video card
windows x64
antec sonata and psu that came with it

Any help would be greatly appreciated!

If your actual hardware (mobo, vid card, etc) is good, it sounds like a power supply problem. If your power supply is adequate, check your line voltage. If you have other heavy appliances, such as air conditioning or refridgerator on the same line, or your local line voltage low due to heavy summer power consumption, it could cause your problem.

You may need a UPS, or at least a heavy duty surge protector.

Of course, it could be a component problem on one of your components. You may want to test your setup at a friend's house to see if the same thing happens.

Good luck.
