yeah, there was a little rubber blocker thing, but i took it off. oops. the manual itself says 8 pin though, and shows all 8 pins, so idk

nope. you need to plug just one 4-pin in. the rubber blocker was almost surely toward the CPU end of the board. plug in the 4 pin connector (the one that fits - they're different. look at the corners; some are rounded, some are square) to the four pins that are closest to the PCI/PCIe slots.

The One and Only

I would NOT use the full 8 pins. I burned up an MSI motherboard using 8 pins.

I have the 8 pin connector plugged into the motherboard. I have two PCI-e cables from PSU to graphics card. I've been trying to boot with only one card the whole time.

You may have some defective hardware, then. I'm guessing the MoBo doesn't have an LED POST readout on it?

I'd try reseating the RAM, only putting one stick in, and trying different RAM slots, then reseating the CPU, then replugging all the power supply connections, and then I'd send it back if it still isn't working -- worst part is you don't know what's failing unless you can get a POST code. Rarely, MoBo manufacturers include a speaker which will beep out an error code. If you have a case, sometimes they have the speaker built into case with a wire coming out which goes into the speaker pins for a code.

how can i reseat the cpu i dont have any adhesive to reapply the heat sink after ive done that?

what motherboard?

frequently, only one of the 4-pin connectors gets plugged in to the CPU power connector, and the manufacturer (like; MSI) has four of them blocked off with a little rubber thingie that's prone to falling out. read the manual for your board.

just made sure on the bios jumper, the jumper is set correctly, or at least when i move it the same thing happens (no post)

I hate when that happens. Does it have onboard video it could be defaulting to? What's the model of the board?

they boot but are quiet the whole time. they stay running

No change in fan speed suggests there's no CMOS POST happening.

Make sure you have your 4-pin connectors (or single 8-pin connector) in the Motherboard's CPU power plug.
Looks like this coming from power supply:

Plug like this on MoBo (bottom-right of image):

Reseat the RAM, then reseat the graphics cards. Try with only one graphics card in. Make sure the 6-pin PCI-e molex connectors from your power supply are connected to the graphics cards.

Did you check the BIOS jumper? Some vendors like to ship board with the bios jumper in the clear position and you have to switch positions for normal operation.

When you boot up, your CPU & gfx fan should rev up and be noticeably loud, then slow down to near-silent. Does this happen, or do the fans stay revved up?

ok so i just bought a whole new rig, mobo standard msi, nice psu, and when i boot up i just get no video input. the monitor just behaves as if theres nothing plugged in. i got the gpu in the first pci slot, and dvi cables to the monitor, but nothing. everything powers on though, fans are going and i hear stuff working, just no display.
