mind me askin what was the wattage of the first PSU and what is the new PSU that you are to order

The wattage of the first PSU was 500w and the wattage of the second one is 520w.

I have no requested an RMA from the shop I got the mobo from.... going to have them check it over and if it isn't the mobo then it's got to be the CPU.

Another thing, when putting in the CPU it takes a bit of force. I would have guessed that, and I've made sure that it's going in properly. My question is that should a CPU have marks from the contact points of the 775 socket where the points make contact with the CPU?

I never would have thought that you would have to use force as the one I got just kinda fell in place without any force at all. But then again it could differ with different CPUs as well. Would be better if more experienced members tell you about this bit who deal with cpu's on a daily basis. But a lil bit force should not be that unusual at all.

Hi Tacticalgs,

I would also say that your CPU is find if all the pins fit properly in the cpu slot on the mother board. Drop a post here when you get your new PSU and let us know how it worked out for you.

Hi there just to add to your theory guys i have experienced this problem on many PC,s and i have found the problem to be the PSU , when you get a few turns on your CPU fan then it most cases its the 4 pin ATX power supply that gives power directly to your CPU, that is usually dead, you can get arround this without buying a new PSU by removing the connectors firstly and then chopping it of and attaching it to one of you standard 4 pin molex connections, if your not confident enough to do this you can buy a convertor for buttons everywere on the web, just type "4 Pin to 12 Volt ATX Motherboard Power Adapter" in your google engine
Hope this helps, oh by the way you can also test the 4 pin molex connections first quite easily with a neat little trick, disconnect everything and take your 24 pin main board power connection..find the green wire and insert one end of a paper clip into it and then the other end into either earth(black wire) on either sider, before you plug it in make sure to attack a internal case fan to one of you standar 4 pin molex connections and when you plug it in it will spin and casue no harm, just a little way of narrowing it down to the 4 pn ATX connector i have learnt from others o the web, you can find that tutorial on Utube i believe so you can watch someone do it before you go messing around sticking paper clips were they might not belong hehe

I have almost the same problem.

My computer is very similar to yours

Gigabyte GA-P35-DS4 Ver 2.0
Intel E6850
2 gb OCz DDR2 8500
WIN XP Pro
EVGA 8800 GT 512 MB video card
500 gb WD HDD
PC&C 750W Silencer P/S and ANTEC 650W P/S

P/S will kick on in high speed, all fans will run, P/S never kicks to low speed like it used to. About 2-3 seconds it runs then turns itself off. It will attempt to restart all by itself for in a loop until I turn off the P/S at the P/S.

I bought a new P/S and installed it. Same results. So it is not the P/S. I reset the VC and RAM. Same results.

This is not a new build. It is about 6 months old. The Thermalright Ultima 90 cooler seems to be still solidly set. I could try to remove and reapply but it was already cured and working for a long period of time.

Any thoughts? I am leaning to a motherboard issue. Have not heard back from Gigabyte yet.

Thanks for your insight

My friend had a similar problem , when he assembled his pc and powered it the fans just flickered
He just placed a new power supply unit and the problem was solved.
wish you the best

As I have already said, it's not the PSU as I have tried two now, both with the same power or more.

I didn't force the CPU into the socket.. it went straight on. I'm talking about the lever, it didn't require "force" but it wasn't as if nothing was there - if you know what I mean?

aunistly dont know what you axactly trying to say but if your cpy is properly seated and you lower the lever with slight force at the end all is good.
hope Im with ya on that one

the lever would need a lil force nothing over the top though, to be put in place. so if there you need a bit of push then its all good.
