Hi, I'm new to building computers, but with the help of some tech friends I've decided to just go for it. Here are my specs:

Coolermaster HAF 922 case
Intel core i5 3470 CPU
Apevia Aqua Power 700W PSU
ECS EliteGroup z77H2-A3 motherboard
Gigabyte GeForce GTX 660 graphics card
Ballistix 8GB RAM (1 stick)

All components are hooked up properly (according to mobo manual). I also have a DVD drive hooked up and I've wired the front panel of the computer case.

I've carefully cleaned and reapplied themal paste to the top of the CUP thinking that was the issue originally, but no change! All fans are hooked up via the power supply and run when I power the computer on. I have also been careful to ground myself each time I go in to touch any components/wire/cables/etc.

Is it possible my PSU is bad? After searching through some forum threads, I've gathered that might be the issue...

Heeeelp!!

Thanks so much,
Noah

Hi, If starting the board outside the case with only CPU and CPU fan installed, is it the same?

Actually, I found that if I uninstall the graphics card I can access the system BIOS no problem (no rebooting issue). When the graphics card is installed, I can't get past the POST screen. It looks like it's a faulty graphics card...

My graphics card came with a PCI-Express power adapter that plugs into two 4-pin peripheral power cables. Is it problematic to plug the graphics card directly into the PCI-Express power cord that comes with my PSU? I'm wondering if I might have killed the card by powering it the wrong way...

Thoughts?

Thanks!

It's most likely your power supply. Apevia is not a brand that is known for quality power supplies. From the looks of it it sounds like your power supply is not handling the loads being generated by your system. If you can replace it with a Seasonic or Corsair TX (not CX) series then you should be good to go.

Using the adapters does not always work. Try borrowing a greater PSU and test.

I RMAed both the PSU (return) and graphics card (replacement). Instead of the Apevia, I've ordered a Corsair Enthusiast TX650 to be safe. I'll try the system again with the new graphics card and PSU when they come in and see what happens!

Is there any difference between using the adapter that comes with a graphics card and using a PCI-Express power cable straight from the PSU? I'm just curious whether or not it's possible that I burned out the graphics card by plugging it in wrong.

Thanks,
Noah

The difference is related to the amperage required for the PCIe rail/rails.
If wrongly plugging, then yes, the card can be damaged. If not enough Amps, no damage for the card.

Hi again! Now I'm running a corsair tx650 PSU, and I got a replacement gigabyte geforce gtx 600 graphics card.

AND I'M HAVING THE SAME EXACT ISSUE! After 30 seconds the system reboots! I'm also getting no video output from the graphics card OR mobo.

Without the new graphics card plugged in (using the mobo's default card), the system runs great. I just can't play any games, etc. Once I plug the card in, the system gets all funky, and as soon as I take it out it's fine again.

Is it possible it's a mobo-graphics card compatibility issue?

This is driving me crazy. Help!!

Thanks,
Noah

Sounds like a driver issue more than a motherboard - graphics issue. Maybe try deleting your GPU driver and updating to the latest version.

Well, it seems like a MoBo issue, as the system does boot up. if it were CPU/GPU You would get no video.
