Motherboard is clicking pc wont start.?

Question

about 3 weeks ago my Power Supply Unit(PSU) started making a disturbing noise... I ignored it planning on getting a new PSU as soon as i could. I wasn't having any problems except for having to always turn the pc on twice before it would boot up properly.

2 weeks ago i turned the PC off and then tried turning it on again a few hours later but nothing shoed up on the screen. There were a few clicks coming from the mobo as soon as i turn the power on which didn't used to happen. Everything else sounded like it was working properly, But its hard to tell what was happening without being able to see anything on the screen. The PSU was still grinding. It was a 500W.

Then 1 week ago i got my new PSU (500W) and installed it and everything was working fine. No clicks, no noise, nothing! I used it about 5 times over the last week with no problems.

Now this morning i tired turning it on and the clicks were back! it's def coming from the Motherboard. The new PSU is working fine-no noise.

help!

I forgot to mention that nothing displays on screen .. Maybe bios is loading but theres something wrong with the display adapter? Or maybe bios is not loading... after the 11 clicks however there is the normal beep .

Also, If i disconnect the ATX_21v the clicking stops.. but obviously Nothing displays on screen

of course i mean AT_12v

Okay i found the culprit.. its my geforce 7950GT card making the clicking. .. i disconnected it, used my old display and everything works. ... but what does this mean for my graphics card? is it fried ?

My graphics card could be damaging my PSU?
i didn't know this was possible!

Yes my new PSU is a lot better quality than my old one... same 500watts.

I have also heard this clicking could be due to a power modulation problem...

Answer 1

From your last update it may be the pwr suppy is not pumping enough pwr to the video card, the 7950GT. Or the card has crapped out.

The video card could have been the problem taking out your other power supply.

Is the new pwr suppy a "good" quality one?

Hate to tell you this. BUT, THE COMPUTER IS D.O.A. . I had similar problem with a computer of mine. Bought new PSU, came right back on and work all of but 2 days. Same symptoms. Took it to a computer geek store and they told me after having gone through with a fine tooth comb, that the motherboard suffered several power surges and has finally blown several resistors and other components. Asked about new motherboard and the case I had wouldn't be compatible with the newer type motherboard and if bought new board from manufacturer it was about 300.00 . It was cheaper for us to have them build us a computer for what we wanted to do w/dual processors. They tested everything in the computer right down to the memory sticks and like I said found the motherboard shot. But they ended up putting the hard drive into the new computer and making it the slave drive so we didn't lose any info that we wanted to keep. But had to reload all games that we played back onto the new hard drive.
I hope this helps.

If I were you, my first course of action would be to return the 550v psu and the motherboard to the supplier with a description of what happened and demand a replacement or a refund. Failing that, get another 550v psu to test the motherboard. Then you will know if you need to replace it or not.

Answer 4

Hi. There are very few components on a modern motherboard that would click. Relays can and do but are uncommon. Try and isolate the sound. It may be a fan on your GPU.

Answer 5

Perhaps it's your CPU fan?

In this case you really need to take the side off of the case to find out what part is causing you grief.

Answer 6

Have you made sure the motherboard is connected properly, it could have came loose and the clicking noise could have been from it being loose trying to keep it connected.
