cpu too hot on clean system

Specs: 7 ultimate 32bit, 2 GHz / 1982 MB
Hi,
This is not to be confused with my laptop cooling problem post as this is my bedroom tower with the similar problem.
Ok, my system is an AMD dual core 2.9, and even though the heat sinc is pristenly clean and the fan too, and I also used arctic silver paste, the cpu shoots up to 90+ c at the light hint of a load. when idle it's happy at 29c, and also stays that way when watching HD video. but the second I put even a basic game like Farm Frenzy (not very graphic intensive at all, nor cpu), up it goes in like 5 seconds. after 15 the pc will shut off if I don't close it.
The thing is, I have a pci express2 nvidia 9600 1g graphics card, but I can't monitor that to give a reading. None the less, the cpu should not do that.
I have tried stripping down, and re-seating the lot (with fresh paste) but it hasn't worked.
I've made sure it's all sat properly, and I have also checked the cpu fan is spinning (graphics card fan is spinning too).
I don't know what else to try, but right now, I have a huge expensive brick of a dvd player.

Full specs are..
AMD dual core 2.9 (seated with arctic silver paste)
2 gig ram
Nvidia 9600+ 1gb ram (using dvi to HD tv)
I'm using windows 7 but that shouldn't make a difference.

Thanks for reading.

Could be your power supply. If it's trying to keep up, it cause an overheating situation.

And make sure you haven't put too much paste on the cpu as that can cause it to overheat also. It takes a small amount of paste that has to be VERY thin to work correctly.

Do you know, I just looked at the psu, and it's only 250 watt, so I reckon you hit the nail on the head there. I am going to put a 450 watt in as I have some spare psu's. I'll post back tomorrow as It's way late for me now, so first thing in the morning I'll try it and post back.
Many thanks!

Sorry for late post, it seems my psu 450 watts is a duff, so need to buy a new one. if a new psu doesn't fix the temp I will see if I can get a replacement processor from AMD and claim a faulty temperature probe. Only because I noticed, when I closed the game, the teperature reading instantly went from 98c to 43. no heatsink or fan can make a drop like that in under 1/2 a second.

True. Post back if you can. I'd be interested in hearing what happens. Best of luck.

Thanks. I'm a bit of a geek, and have 5 towers at home. I am going to just try a psu from one of them just to test, so I'll post back sometime tomorrow. I have my wedding in a few days, so just juggling the spare time to do whilst keeping the missus happy with the planning also lol.

Well! Congrats. But do you really think your wedding can't wait until you resolve the over heating problem? You're setting a bad precedent with the missus if she comes before the computer. :)

Gotta keep the ladies happy.

Best wishes.

Hehe, well that depends on if you're going to use the pc for the disco, and require visualisations to run without overheating and tripping out. then I think an overheating problem would be the very least of my problems hehe. Well I have replaced the psu with a slightly higher one, it's 359 watts which is better i suppose, and so far it has actually improved. It is getting hot still but not as bad. it is averaging at 55c under a normal load, so I'm happy with that.
I wonder if I should ask the old man for a psu as wedding gift haha.
Thanks seawatch, I've learnt something new about pc's, I wouldn't have thought a low wattage psu could heat a processor.

When you get back form the festivities, put in a bigger ps.

Best wishes to you and your lady.

A long and happy life together.
