No display, hard to turn computer on

Greetings,

I decided to build a computer by myself. Here is my hardware:

Graphics card:
GeForce GT 440 / PCI-E 2.0 / 1GB GDDR3 / 128-bit

Motherboard:
Gigabyte GA-965P-DS3

HDD :
WD CAVIAR SE16 320GB SATA2 16MB

Power Supply:
ATX 500W 12 cm

DVD-RW:
SMG DVDRW 22X SATA

Processor:
Intel® Core™2 Extreme Quad-Core / Core™2 Duo

So I have put all together and tried to turn it on, so I have 2 problems:

1. It is not turning from first time, I have to press it 4, sometimes 6 times and it is turning on.

2. When computer is turning on, all fans are spinning (case fan, psu fan, gpu fan), so it seems to work ok, but I have no display on my monitor.

I have plugged in monitor, I'm sure. I calculated that 500W is enough for my hardware. Tried to reinstall RAM. Tried to reset CMOS (by unplugging bios battery for 10 or 20 minutes.

If you will need some more details or more pictures just ask.

Sorry for my bad english.

Thank you very much for you help and your time ;)

What brand is your 500W PSU? Sounds like that might be the problem with turning it on.

I don't see a brand, but since its a 360 Watt PSU labeled as 500 that's not a good sign.

It's not a power supply issue. Did you plug the 4 pin CPU power connector from your PSU to your motherboard? Did you connect 1 24-pin ATX power connector? Sorry the pictures are very bad quality I can't really see them connected.

Also, did you install a beeper than you got with either your motherboard or your case?

And are you sure you connected the case the right way?

I connected the case by following the motherboard's schemes in it's instructions. But I will try putting them in other places

About the beeper, I'm hearing of it at first the time, can you explain me, what it is and how do I install it, please?

Btw, I'm not hearing no beeps while it's on

It looks something like this:

If it's installed, it beeps about computer problems, and there might be ONLY two reasons why it's not beeping:

1. It's not installed.
2. Your CPU is either wrongly inserted or dead.

Ok, so I will look in my other computer if I have a beeper

Beeper plugs near the small F_panel connectors? Here is "speaker" place in their right, I need to plug it in there, yes?

Yes exactly. I noticed something on your picture, one second.

See that unused plug slot? That's the 4 pin CPU power slot, without it, no computer will work. Your processor isn't turning on because it's not getting any power.

Thank you very much for helping me :)

Well, that fan isn't getting power from cpu power socket, only the CPU itself. Did you find a beeper?
April 7, 2012 3:19:06 PM

Found it in other PC :) . Connected the beeper, turned it on. I hear unlimited short beeps, soo quick and short

According to your motherboard manual, it's power error. Triple check ALL the power connectors, the only important ones should be the CPU power connector (the one I circled in the picture above) and Motherboard 20-pin one. If it still doesn't work, it might be power supply at fault. Also, you may try switching power supply from your other machine to check whether it's power supply indeed.
