OK so i got a HAf 922, AMD 965 BE, asus m4a79xtd evo, corsair 750 watt PSU.

The mother board green LED light comes on when i turn on the PSU power. But when i hit the case power button nothing turns on, no fans spinning or anything. Im pretty sure i connected everything i needed to. I plugged the HDD and DVD with sata power from the PSu and the sata from them to the mobo, the HDD is plugged into the sata E1. I have 2 pci e in the 5870. there are 3 cords not plugged in, 2x PCIe and 1-4pin one. I have some picture but i need some help. When i push the power button on the case, i see the PSU fan move like an inch.








so many wires!!!!

Please perform EVERY step in the READ before posting about boot/no video problems! sticky at the top of the forum.

It sounds like at least one of your problems is #2 on the checklist. The 4-pin CPU power connector isn't on the motherboard for looks. It provides the CPU with power. The system doesn't have a chance of booting without power to that connector.

I guess I mis-read your post. It sounded to me like you didn't have the 4-pin CPU power connector plugged in. Either way, let us know how it goes after you've performed EVERY step in the checklist linked above. It was created to troubleshoot this exact type of problem and will fix the problem 90% of the time.

Well i took everything out. I wasnt able to get the stock heatsink and fan out because the thermal paste i put on seems to have glues it down. Im gonna build it again.

no pins are bent, the PSU is definitely on. Also the mobo is getting power cause on my mobo i read in the manual theres a green LED that lights up when its on/ready. And it comes on when i hit the PSU switch. i dont see any pins that are bent.

Not true.

The green LED is powered by the small independent 5 volt standby power supply inside the PSU. All it means is that the PSU is plugged into the wall and the PSU switch is on. It has nothing to do with the main circuits that actually power the PC.

You sure you have the cable from the case attatched to exactly the right pins on the motherboard?

that took me 2 tries to get right with this build.

Because if your on button isn't connected to anything, well...
