Recently i've attempted for the first time to build a computer, but i've had several problems and am afraid that I will never get it to work.
My problem is after I install the parts to the motherboard and power up the motherboard and CPU I get "No Signal" on the monitor.
I have litterally tried every solution to fix this problem the the problem still exists.

These are some of the solutions I have tried so far
. Build outside of the case
. Keep the essential parts on to test ( CPU + Fan, 1 Stick of Ram, Graphic Card )
. Tried to use the onboard graphics ( Taken the graphic card out for meantime )
. Tested the ram in different ram slots
. Clearing CMOS

Just to add that I have had 2 motherboards, 2 CPU's and 2 kinds of 4GB ram, since I was convinced they were the ones faulty but obviously they weren't ( Replacement for the 1st CPU and a refund for the the 1st motherboard then got a different motherboard, DDR2 ram for first motherboard then I got DDR3 for the next motherboard )

Here are the specs:
( Original Motherboard ) Sapphire PC-AM2RS790GX Socket AM2+
( Orginal RAM ) Corsair DDR2 4GB RAM
( Current Motherboard ) Asus M4A79T-E Socket AM3
( Current RAM ) Corsair DDR3 4GB RAM
AMD Phenom II x3 720 ( Socket AM3 )
Corsair 750W PSU
Asus HD 4870

So far I have tested 2 motherboards and 2 of the Phenom 720's but still the fault exists.

I have asked around on some other forums but I have had useless answers which did not fix the problem, I saw that some people has also had this problem in this forum so I thought it'd be a good idea to try and get help here since some of the victims of this had this fixed by the solutions here but I tried them all and still it is not working.

What happens is everything is on, I hear no beeps from the motherboard, everything is functional like the CPU fan and the DVD drive and HDD but obviously I taken them off to test with only the essential parts.

Quite frankly I am starting to get fustrated with this and just probably give up, also all the parts I bought was new except the PSU, so I really think it could be the PSU now since it is the only componment I haven't returned and got a replacement, and lastly I do not have a friend with parts to test it on so I am unable to go with that solution and also I do not have spare PSU's or any other part to test to see where the fault lies.

Anyway heres a picture of the parts I have connected this picture has the graphic card slotted in but I have also tested with onboard card.

Welcome to the Forum FarePak!

Fear not, as I'm sure the talented Techs and helpful members here will have an answer for you!

Thanks for the information that you have already provided. That always helps to get things going in the right direction.

Marking this open to encourage our clever hardware folks to come and take a look.

Thank you for your patience

Thanks, trying to solve this problem is starting to get very fustrating and im starting to regret even getting the parts to assemble a computer.

Also in the picture the graphic card is in the 2nd PCI-E slot, just to let you know that I was trying to 2nd slot since the first one weren't working also and then forgot to put it back in the 1st PCI-E slot for the picture.

Ok, thanks for that information.

Frustrating, no doubt, but once it's all working, it makes it all worth it

No worries on which slot it's in.. you were correct in trying another.. I've done the same many times.
Same goes with the RAM.. you can't put them in wrong, but you could, perhaps, put them in the wrong slot. Make sure you're in number 1.. I know.. redundant.. I imagine you've checked that over many times!

Patience is key here as our Techs and Staff are positioned all over the world. I'm sure that someone with better knowledge here than I will be along just as soon as possible.

Have you tried another monitor?

I have tried 2 monitors and a TV, but still haven't had any luck.

Hi farepak and welcome to the forum.

Does your pc sound like it's trying to boot, by that I mean do the fans spin and does the hard drive sound like it spins up ?

and your monitor just gives you a "No Signal" message...

If this is the case then I would suggest trying another PSU.

*EDIT* Having read your first post more carefully I believe the PSU will be your problem
