hi im having some trouble with my new computer , i sent the motherboard back as i thought it was faulty but it has been tested with other components and worked according to the place i purchased from. and when i got it back it did for about 10 min, then it will shut down and restart and do this 2-3 times . and now it dont even start up it , i will press the power button and it will turn on but the fans will go to fullspeed on the cpu the graphics card and the case on the motherboard, 3 small lights light up indicating the cpu is working at full load according to the motherboard manual , and nothing will appear on the screen during this , i get 1 beep at start up representing start up is ok, then the fans kick in . i wanted to know how i should test to see what the problem is, im thinking its the motherboard or psu. please can someone help me out?
also when i first put the computer toghter it was working fine for about 2 weeks with no problems then it started doing what i hav siad above thats why i sent the motherboard back as i had 28 day instulation damage cover , which has now expired.
my componets are
motherboard : gigabyte ex58-ud3r
psu: corsair hx 750w modular uk version
gpu: ati asus hd 5870
cpu: intel core i7 920
ram corsair 6gb ddr3
thanks
ricky

i turned it on again today it strated up and then with in 5 min it shutdown and did the fan thing ( fans went at max speed on the gpu and cpu), i waited a few min and tried again but now it is not even starting up .as i press the power button on the case and i see the fans move for a split second and one fan liights up (as it is a fan with a led ) for a split second as if the system were just about to start up and then nothing, and it wont turn on again , so i unpluged it and waitd few more minits and tried again the same thing happened , so could this be a psu problem ?

Anything is possible, but it seems unlikely that it is a PSU problem.
I would strip the system down to the minimums; one stick of ram, no drives, only connect power switch...nothing else. If it starts like this, then you can start adding parts back in one-by-one untill you find the problem part.

ok so, i dont think it is a heat problem , when it was working i checked my gup temps and it was idol around 36c but i didnt have time to check the cpu temps , the case is very clean inside as are all of the components as they are relativley new, just rulled out the possible heat problem as i have just tried to start it and the fans did the thing where they moved for a split second as if the system was just about to start up , but nothing and then the powerbutton after this has no effect on the system , no fan movements what so ever. how could i figure out what component is at fault ?
ok i have just rembered its not my gpu as i have tested a different one and had the same problem with the fans running at full speed
i also tried turning the computer on with just 1 stick of ram no gpu and ho hdd or dvd drives atached , and still have that thing where the fans move for a split second . so im thinking it is the psu, as the motherboard was tested with other componets and it worked fine.
so its down to the psu or cpu but i have no way of testing either of the 2. could a cpu cause this im thinking not as it probley dont even have time for any power to reach it as the system does not start up .

Given those two possibilities, I would try to rule out the PSU first. I agree with KillerBug, the Corsair HX is a quality PSU, but stranger things have happened.
Do you have access to another PSU--any old ATX-compatible PSU--that you could try just long enough to verify if the Corsair is the source of the problem? If a different PSU gets you further than you are getting now, then you can concentrate on that. (Doing a hard reset of the CMOS would probably be a good idea, too.)

i have a 400w corsair psu in my secondary computer the one im on now but i dont know if its powerfull enough to run the other computer with all of its components, could i try just starting up with 1 stick of ram no gpu and no hdd or dvd drive surley 400w is enough for that ?

ok im certian ist the psu as i have just tried the 400w psu and the system started straight away with no problems, after i tried the 750w one thats broke and it failed to start doing the thing where the fans move for a split second. does anyone know if i would be able to get a replacement from the place i brought it from or from the manufacture?
yeah i figured out how to edit messages, anyway i went on to corsairs webpage and read up a bit and found that i should do a paperclip fan test , which envolves putting a metal paperclip between the green wire and any black wire and then turn thepsu on and the fan should spin to show that its working, and guess what it spinned for a split second and then stopped just like my pc was doing , i then proceded to fill out the rma form and should get my instructions of how to send it back in a few hours. anyway thank you all for your help with my problem.

Good work! It is unusual for Corsair PSU's to fail, but they should get a replacement out to you in good order.

Just to follow up, you can check on page 32 of your motherboard manual for instructions on clearing your CMOS. Basically, you can remove the battery from your board for a minute or two or you can find the two-pin CLR_CMOS header next to your SATA connectors and short the pins together either with a jumper or metal screwdriver blade for about five seconds or so. That will set your CMOS back to its factory defaults.
This can come in very handy if somehow your CMOS parameters become so corrupted you can't even boot your system.
Again, good work on finding your problem.
