Post what components you're using, otherwise it could be anything (and I mean anything) under the sun.

What kind of RAM, and how much of it? What is the CPU? What kind of heatsink/fan is on it? What have you done so far? Did it not start up from the get-go, or did something happen after it had been running for a little bit? I know it's a lot of questions to throw at you, but the more information you can give us the better our chances of narrowing down some of the problem.

Does the computer post at all? Do you hear any beeps at anytime if you leave it on for a few minutes?

This could help determine the difference between a mobo or gpu problem.

oh hyea sorry my cpu is q6600 got stock heatsink with it and two stock fans on the antec 300 case
ram is ozc 4gigs,my rig worked first time i started it up all the fans did anyways but on my screen it says no signal

there is also 3 red lights at the back of my 4870 could this be something
January 30, 2009 11:41:46 PM

not hearing any beeps from my rig either

Red lights are generally a bad thing. I would re-seat the GPU and double check that the PCIe power is plugged in all the way into the 4870.

The manual should tell you what the lights mean.

Okay--I am going to assume that your monitor is plugged into the graphics card, but the lights usually indicate some power issues. Have you plugged in both 6-pins into the radeon for power? Is it correctly seated in the correct PCI slot? Sorry--giving my daughter a bath and I've been in/out of here.
January 30, 2009 11:57:05 PM

yeah both 6pins are plugged in this is so anoying
January 30, 2009 11:57:44 PM

yea the 6pins are plugged in

January 31, 2009 12:11:02 AM

check the 4/8 pin cpu power next to cpu socket...

there was a cap ontop of one of the four pins i just plugged it in gonna check if it is working i hope it is
January 31, 2009 12:16:17 AM

that's the one...plug that in and you should boot up
January 31, 2009 12:20:03 AM

yeah i wish it would boot up but its still not so annoying
January 31, 2009 12:28:55 AM

what's it doing now?
January 31, 2009 12:30:33 AM

the same no signal on screen 3 red lights still there on the card
January 31, 2009 12:37:36 AM

Make sure the card is seated all the way....look real close at the bottom, it should be flush in the socket. Unplug everything except the video card, 1 stick of RAM, and HD.

HD4870 LEDs

D1601 - Red LED On, shows critical temperature fault

D1602 - Red LED On, shows External power connector A was removed

D1603 - Red LED On, shows External power connector B was removed

D601 - Red LED On, shows critical Core power fault

At BOOT/POST, the card's fan will spin @ 100% for a short while and 3 of the 4 LEDs will light up for a brief period and then go out ( D601 should remain unlit ). This is NORMAL behaviour as the card is performing it's own type of POST test.
January 31, 2009 12:58:48 AM

D1601 IS ON
D1602 IS ON
D1603 IS ON
what can i do
January 31, 2009 1:40:58 AM

did you plug in the internal speaker on the mobo? It could be giving beep codes that ur missing. You should have the psu plugged into 2 spots on mobo, and 2 on video card. Check the bracket of the video card to make sure it's not hung up on the mobo, and that it's seated all the way. I hate to point out the obvious, but is the monitor on and plugged in?
January 31, 2009 1:59:31 AM

yeah monito is on and plugged in,the psu in
s plugged into the mobo twice and the card dammit what is wrong
January 31, 2009 3:01:30 AM

sounds like PSU or video card. perhaps eliminate video card - can you try an old (low Power) video card? also, with that low power video card, do you have an old PSU you can try?

take a break. get a cup of coffee or fav beverage. disconnect everything and remove the ram. and then reconnect - double check everything. test again. if that doesnt work, disconnec the video card and do start-up. you wont see the screen, but you can hear it boot up when it does.

the video card is giving power codes. could be bad PSU - happens all too often. I know it sucks and its discouraging, but keep your head in the game - its not your fault if you got a bad PSU or video card - so you RMA and get a new one! Call tech support for your video card and have them walk you through it one for time. Then call PSU tech support and do same. Maybe you send up with replacement PSU and v.card. So it goes. I just friend a mobo in the middle of a deadline on my workstation. Murphy's Law is still alive & well. I went on a job and BOTH of my car headlight bulbs failed at the exact same time!! in the freaking freezing cold!!! I had one spare so I got out okay from the middle of nowhere! It could be worse - like Columbia crew RIP.

make sure nothing is shorting your mobo - like contact with metal on the BACK of the board. Im new here - just brainstorming while the superheroes here arrive on scene lol

Ur card should have dual DVI ports, try the monitor on the other port.

Do you know anyone that has a computer? Ask them if you can borrow their video card for a few hours.
January 31, 2009 4:55:22 AM

Have you tried booting with just one stick of RAM installed? If it still doesn't work, try the other one by itself. What model is the RAM? "ozc 4gig" doesn't really tell us much. Is it a 2x2GB kit? OCZ RAM usually needs quite a bit of voltage to work correctly.

the motherboard is touching of the screws in the case which are under it but how can i stop that
January 31, 2009 4:12:26 PM

There should only be standoffs under the holes in the motherboard. If there are extra standoffs they need to be removed.
