gpu gives no video

Specs: n/a
yo. i finished my first build in excitement only to get a "no signal " my monitor . no boot screen no nothing .everything powers up though.
monitor: asus vh242h
mobo: gigabyte GA-EP43-UD3L
gpu: ATI Radeon hd 4870 512mb GDDR5MEMORY
cpu: intel daul core processor pentium(R) processor E5200
RAM: two 1GB PATRIOT PC2-6400 DDR2
PSU: 550 wats

the monitor is brand new so thats out of the picture. i believe it to be the gpu but im not sure. i have a vga adapter for my other tv, and upon connecting it via vga , it also got no connection. on the asus i tried both vga and dvi and still "no signal". its not the motherboard . i sent it back when i suspected it and the proprietor tested it and sent it right back to my. also sent my psu back and it was fine they claim. i dont wanna accept the gpu being the culprit seeing as its new. although it did spend a idle 3 months laying around in my hot attic out of the box. maybe that contributed? anyways thanx in advance for any help guys.

1st, you should ALWAYS benchtest your components BEFORE you install them in the case.

How to Bench Test Your System

2nd, 550W PSU means nothing. We need the make/model & amperage rating on the +12v rail.

3rd, do you a different video card you can try? even a standard PCI card? The HD 4870 is a bit on the power hungry side...that's why it requires two 6-pin PCIe plugs. If your PSU is a cheapo, it may not be able to handle the load of the card.

oh i guess i should have mentioned i have it "benched out" lol.

psu: Lifetime Series Pro 550W Psu

dont have another card. this is my first build :(. tiger direct made made this build so perhaps the 550 is more than enough......hopefully.

"oh i guess i should have mentioned i have it "benched out""

So that means you currently have all the hardware out of the case & laying on the bench, right? Because if you actually did benchtest your hardware & found that it didn't work, it would be stupid to put it in the case.

"perhaps the 550 is more than enough"

The wattage isn't as important as the amperage. Your PSU is an ULTRA Lifetime Series Pro 550W which has 30A on the +12v rail. That should be fine as long as your PSU isn't a dud.

Do you have both PCIe 6-pin plugs connected to the card? It won't work without them.

@kuwese, with everything connected the cpu fans spins and everything powers up. lights on mobo and psu , led lights ect. i hear beeps too. i know that my mobo has a beep code , but i dont know the standard for a short beep and a long one. any audio clips?
without the ram, it constantly beeps for a while then shuts off. then powers up again. i noticed the cpu fan going slower .
@jam,yes it is all out of the case, except for the psu because mines is hard to screw in ^^. yes both pcis are plugged in, even tried it with one.

Did you try booting up with just one stick of RAM, and in different slots ?

When necessary components installed and start the system do u hear long or short beep?
short beep=single tone and u can hear it very fast.

"yes it is all out of the case"

OK, no HDDs are connected, right? Because at this point, all you should be concerned about is getting a display. The only things that should be connected to the motherboard are the PSU, CPU w/HSF, video card & monitor, ONE stick of RAM, case power switch (unless you're jump starting with a screwdriver), & the keyboard. Nothing else should be connected!

That fact that you're hearing beep codes is a good sign. Your board uses an Award BIOS, here's the beep code list:

@kx5m2g,with one RAM stick individualy booted in each slot , the same thing happened when they boot. one beep and eveything powers on.except for the first boot in channel DDR2_3. when it powered up the cpu fan speed slowly and the gpu fan kept speeding up and slowing down unil i turned the system off.i tried it again and it booted up as it did in the other slots. also id note that after the beep on boot the mobo lights turn this standard?

@kuwese,i think its a short beep, it lasts about a second.about how many seconds is a long beep?
@jam,yes i only have the essentials plugged in. i also have the mouse in though.

"i also have the mouse in though"

Disconnect the mouse, it's not essential. And the keyboard should be PS/2, not USB.

Are you sure you have the heatsink installed on the CPU correctly? Fully locked in place? Used the correct amount of paste & oriented it on the CPU correctly? 4-pin ATX12V plug is connected (just behind the PS/2 ports)?

Also, is your Patriot RAM called "performance RAM" that is supposed to run at an outlandishly high voltage such as 2.2v? DDR2-SDRAM is supposed to run at 1.8v. See if it's on the supported list:

@jam,ok ill disconnect it. should i disconnect the keyboard too, because its a usb one. yes i reinstaled the heatsink/cpu/cpu fan . 4 pin i reconnected.

the ram? it says "extreme performance " on the side. your link didnt work for me so i cant check. ill try and check the specs where i bought it though.............oh actually the label on the stick says 1.9v

is 1.9v too high? should i buy another video card and RAM?
