With the new one, the first time i turned it on it booted up fine. If I click to restart my computer, it never turns back on. When I turn it on manually, it doesn't POST. I turn it on and off like 3 or 4 times until it finally POSTs. Can someone please help me figure out why I have to keep turning on and off my computer for it to boot up each time?

Check that all your cards are seated properly, and that all your cables are also seated properly.
If you've got more than 1 stick of RAM, try them 1 at a time.
If you've got onboard video, remove any graphics card & try that.
If you've got more than one HDD, disconnect your non-OS one
Just boot up with the bare minimum - keyboard + OS HDD + 1 stick memory.
Take it from there, plugging in/installing one at a time & reboot until it fails.

Did you install the mobo yourself or have a shop do it for you? There is a possibility you have a short from the mobo and the case. Please follow the instruction below to isolate the mobo and make sure to discharge yourself before touching any internal components by touching something metal right before touching the system.
Disconnect everything from the Motherboard except
* keyboard
* mouse
* video output
* 20+4 powercable
* 4/8 pin 12v wire both coming from the powersupply,
* Cpu fan wire
* power and reset button to the case
*case speaker
Now you should have NOTHING connected to the motherboard except what was listed above.
The goal here is just to test the mobo:
If the computer still will not boot up the please remove the motherboard from the computer along with the power supply
place the motherboard on a piece of card board larger than the motherboard,
this will eliminate a short from the mobo to the case witch could be a possibility
Install the cpu with, 1 stick ram in dimm 1, power supply, video card, case switch and case speaker
Connect ps2 mouse and keyboard along with the monitor
Repeat the above and power on
If the computer now boots into bios you most likely had a case short so make sure when installing the motherboard in the case that you use standoffs and they line up with the mounting holes in the motherboard and none of the standoffs touch anything else on the underside of the board.

just in case anyone is wondering, I got this to work by only plugging in some of the fans and not all of them. My CPU and MB stay below 40°C so I guess I don't need all the fans anyways. My power supply is 550W so I don't know why it can't handle 5 fans instead of 3. Maybe I'm using the wrong wires from the power supply.
