Processor saturates in cyclic manner

[Nutty]

I am on Asus M2N68 AM motherboard. My problem is that whenever I play, my processor runs at 100% of cyclically manner for about every 2 min and along with that my screen freezes for 30s. It then starts of as if nothing happened.

My config

AMD Athlon 64 x2 dual core 6000+
Motherboard M2N68-AM PLUS
Asus EN9500GT graphic card
Power supply: 480W
RAM 3GB Kingston 333MHz

I tried checking for spyware, trojan, virus, etc but didn't find anything. I am now assuming that my motherboard is unable to manage my processor. I also tried to underclock my processor but still nothing happens.

Please help me!

When and what are you trying to play?

It could happen certainly because of your power supply. According to me your system is not having a good and proper power supply from the unit.

Thank you for your advice on my power supply. But I took 480W because my friend advised me that for my config. He runs a computer shop. Even I would have preferred a 500W instead of a 480W. But it said its completely useless to invest on higher power supply.

Do you really think that my concerns may come from this PSU?

Certainly yes. Generally this happens with a power supply with no-name, but a 500W is of no use, a good corsair or antec 450W would be quiet enough for your config.

You should know that the no-name 480W, in fact delivers half the power that is displayed, but your config is too fair. You more often have unstable voltage (for power, how you look it sort of amps on the 12v and you multiply that number by 12, if such results in 20 amps, 12V x 20A = 240w, knowing that it is on the 12v, the majority of power is consumed).

Keep this in mind, before any purchase, test it, update the BIOS, and possibly reinstall windows with all drivers updated.

You can also try a battery test (OCCT, memtest, etc. ...).
