Im a NEWB at computers this is my first build and im having problems with video output the monitor works
and ive tried vga cable, dvi cable,dvi/hdmi connector, dvi/vga connector, svideo to component and i still get no signal there is no onboard video i can see i reset the bios by removing the battery for five minutes i tried both PCIE slots i even went and bought a diamond stealth x1550 i have no beeps from the motherboard

all the fans work on the motherboard, cpu and the HD4850 so its getting power. there are two red leds that are lit. Is that normal?

CPU: AMD Athlon 64 X2 6000+ Windsor 3.0GHz Socket AM2 125W Dual-Core Processor Model ADX6000CZBOX - Retail

Graphics Card: VisionTek 900241 Radeon HD 4850 512MB 256-bit GDDR3 PCI Express 2.0 x16 HDCP Ready CrossFire Supported Video Card - Retail

MOBO: GIGABYTE GA-MA790X-DS4 AM2+/AM2 AMD 790X ATX Ultra Durable II AMD Motherboard - Retail

Memory: G.SKILL 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) Dual Channel Kit Desktop Memory Model F2-8500CL5D-2GBPK - Retail

PSU: Rosewill RX750-D-B ATX12V v2.2 & EPS12V v2.91 750W Power Supply - Retail

i would appreciate any and all help thanks in advance.

Did you plug the 4/8 pin 12v CPU connecter in?

You got the righ power going into the GPU? Both conncted?
August 18, 2008 2:15:12 AM

i plugged the 12v PCIE connector on the MOBO as well as on the Card on the 4850 the diamond does not have a power plug on the card so i just used the on on the MOBO

Theres a 4/8 pin around the CPU it needs power or you wont get no where.

The Diamond video card is the Stealth x1550 which has no power connector the Visiontek Radeon HD 4850 does and i did connect it as well as the PCIE power supply on the MOBO
August 18, 2008 2:35:02 AM

Is the memory im using compatible with this MOBO CPU combination or do i need to drop to a slower memory
August 18, 2008 2:36:10 AM

the gigabyte says it can handle DDR2 1066 as long as the CPU does but i dont know if can

This sort of problem can come from a wide range of things, especially when it's your first build.

You need to carefully check everything, make sure it's seated right.

24 pin ATX connection
8 pin CPU connection
Verify any jumpers on the board are correctly set.
Take out memory except first stick.
Make sure all the small connections are in the right spot. CPU fan, case switch, case reset switch.

It's possible that your BIOS needs to be adjusted to run the memory.
If it won't boot with one stick, try the other.

Make sure the motherboard is only making contact on the back side, with the standoffs. Make sure the only stand offs in place are the ones lined up with the holes. If a single standoff is touching the motherboard in the wrong place that would be a big problem.

i ran the different memory combinations with both video cards as well as taking out the mobo and placing it on a cardbard box to ensure no grounds on the case and still no effect i checked all the power supplies as well

if its the bios how do i flash it w/o being able to see what im doing any ideas
August 18, 2008 3:18:47 AM

So you used the pci-e 8 pin to plug into the mobo? That's probably the reason you have this problem, there is a seperate 8 pin for the mobo.
August 18, 2008 3:19:45 AM

I didn't say anything about flashing the BIOS, I said it might need adjustment to run your RAM.

The only way to do that is boot with a different, more compatible RAM.
August 18, 2008 3:41:16 AM

what would you recommend for the ram
August 18, 2008 5:17:12 AM

Is your monitor's power plugged in and did you turn on your monitor?
=P
August 18, 2008 5:43:58 AM

yes the monitor is plugged and was verified to work throught the vga out on the laptop i have and had great resolution


Thanks Proximon im gonna try some 800 hz memory off the list you provided

Try an out of the case build with only one part each, CPU, Ram, Video, PSU and see if you can get to the post screen.
Insure that all motherboard standoff posts are correct in the case.
There is no reason for you system not to post with the ram you have, you will have to increase the ram voltage to get it to run well, but it should post.
Make sure the CPU is compatible with the motherboard, it should be but I have seen where this can be an issue.
Like everyone else said make sure all the required connections to power are made.

i agree...do what he says :) 
try clearing your bios through jumper...you might have to do it many times before it can properly work...also if you have a friend try using your video card in his pc. Or try a different monitor, this happened with me once, so i swapped the monitor and everything started working. Lastly make sure that your processor is sitting properly on the motherboard

one more thing you said your motherboard has 2 leds that light up...usually that is an error code, call gigabyte and ask em what 2 red led's mean, or maybe refer to a manual...i have the same mechanism with my DFi motherboard; it has red lights which are usually error code and help diagnose any problem. .....can you try running pc 800 ram instead of pc 1066? that can make a huge difference and it usually solves many power/ nonbooting/ video issues...hope this helps man...fixing pc's can be extremely frustrating.
1 more thing, make sure your pc is not being shorted, if your pc is shorted it will boot up but nothing else will happen...no windows...no video....all the fans will run but thats it


try the steps that i highlighted
August 18, 2008 11:49:49 AM

If those two RED LEDS are part of the set of five[x2] or so at the bottom of the mobo they are trouble leds check your manual as to their meaning,,ALSO get rid of the rosewill PSU and get a better one ,like OCZ,Enermax,PCPower also check your mobo's manual and the QVL list for ram compatibility,just remember they are not gospel just a guide,I am presently using ram that is not on my mobo's QVL or in the manual,,go figure..:>)
August 18, 2008 5:17:56 PM

the two red leds are part of the video card and they are always on i couldnt find anything relating to them on visiontek's site.

i have already taken the motherboard out with just the basics and still no video. Im going to go buy some 800 hz ram and try it out i thing the AM2+ socket is the only one that is compatible with the 1066Hz ram this CPU is just an AM2
August 18, 2008 6:34:30 PM

Contact the video card manufacture and ask them what the 2 red light code means.

I'm leaning towards agreeing with Shadowthor and Roadrunner. For your earlier post, it sounds like you used a 6-pin PCI-E power connector plugged into the 4/8-Pin CPU power connector. The image Roadrunner linked shows the 8-Pin CPU Power connector (4 closed). Your Power supply has either a 4-pin or 8-pin CPU Power cable. Make sure this is the cable you have plugged into the CPU power port.

Search Google for "4850 LEDs" and you're find a few posts concerning the LEDs signalling a 12V power error.

problem solved i was retarted and didnt have the 4 pin cable to the motherbaord connected thanks everyone and sorry for the frustration i didnt realize that there was an additional connection to the motherboard other than the 20+4 and the pcie 4pin perifial connection
August 18, 2008 7:55:19 PM

Dude, you are retarded. I asked you that over and over, and over.

Others even asked you. Next time put down the crack pipe and slow down to take time to read.
August 18, 2008 10:33:49 PM

can i mix ddr2 1066 with some extra ddr2 667 ram sticks i got from a friend
August 18, 2008 10:50:41 PM

Yes, you can, but your DDR2-1066 RAM will run at DDR2-667 speeds.

Your asking for trouble if you do.

I'm not gonna explain it because you dont listen, and you couldn't understand anyhow.
August 19, 2008 1:06:07 AM

lol you know it could kill your cpu......:) ...but thats good that you got the problem solved
