Right so i just got my HIS Radeon X1950 Pro and new power supply HX520W Cosair. Now the problem i got is that when the X1950 Pro is in place my computer wont boot up, the fan on the g-card is spining but i just get a black screen ?! now im using my XL800 at the moment, can anyone help me ?
 
Extra power lead would the the 6 pin PCI express. should be a lead straight from the PSU

Does your 1950 have two DVI outputs and have you tried the monitor in both?
 
Is your systems CPU or memory overclocked at all?

I had problems with my GPU when i tried overclocking my C2D a year ago. It was quite unstable and actually chose not to even bother switching on on occassion.

If you can make it into bios (either by resetting CMOS or using another GPU that you know works) then try upping the PCI-E frequency to 110mhz (from 100mhz/auto).

Nope stock settings. Ive tryed upping the frequency to 110mhz and the alarms are still going off :( im really not sure what to do now, thought it would be pretty straight foward. So ive got a brand new g-card sitting not doing much, its wierd when i boot up a little red light on the g-card card flashes then goes off and the fan still spins so surely the card is working?

On reading up on the internet, you can either have a 6 pin connector for PCI-E which you either need an adapter which is from a 4 pin molex to a 6 pin graphics connecter or your PSU already has 1 as standard.

If it is an adapter that you get with the graphics card, try it on a different rail from the PSU into a different 4 pin molex plug. Of course, this advice is useless if the connector is already straight from the PSU.

I'm not clued up on the new technology much... I'm still chugging along on my P4 2.4GHz processor which is pushing 5yr old nearly!
 
Yeah i have a 6pin PCI- E connector from the PSU to the card. now whats wierd is that the PC is booting up (I can hear the hard-drive working as if its loading windows) but i get nothing on the screen and as i said before the FAN on the G- card is spinning. Dont know if this helps ? could it be my mobo? maybe re installing drivers for the Mobo or should i uninstall the old g-card drivers? (which are ati one's still)

the motherboard alarm makes a noise?

What error beeps does it make eventually?

As the previous dude said, if you have another 6-pin pci-express cable in your psu, try that. If not, and and see if your graphics card came with a 2x4pin molex connector to 1x6pin pci-e connector, and try that instead.

Something like this:

It wouldn't be drivers or anything yet so no need to worry about that untill you can get into windows properly.

Don't worry about drivers as i said :) The card doesn't need drivers during boot-up to display an image :)

Yep the Molex came with the G-card and i have tried both and get the same problem. When i boot up i get 10 quick *beeps* and then they stop pc still runs but black screen, but twice out of about 10 restarts the fan on the g-card stopped the rest of the time it was moving (doubt that means anything) also i noticed if i didnt have the 6 pin PCI-E cable plugged in to the card the red light stayed on, but when in of course flashes once but then stays off. :confused: i am very confused and doubting the worse :(
 
Additional checks....

Try the other power outlet on the cosair. Mine took a bit of clipping in.

Check is evenly sat in the PCI-E slot. Sometimes case or bracket varience causes a problem.

If all else fails, try loading fail safe defaults and or reseting the BIOS to force the board to reassign IRQ's.

Do you have any other cards in the system that might confict?

Also check your power connections to the mainboard are correctly fitted.

Might be really simple fix.

Turn everything off. Turn on Base unit first. Wait a second or two to let the video card boot. Turn on Monitor(s) so it can fire up and sync with the already working video card.

I have to start my system this way every time.
 
Use the direct PCI-E (dedicated) cable from the very left side of the PSU to your graphics card. The corsair should support it no problem. I have that PSU and easily ran an overclocked x1950xt on it. Run the rest of the equipment from the right hand power ports. This should give you a dedicated rail just for the gfx card (on the hx520w only i'm referring).

Also, do as suggested about powering up, but also try reseating the card and connectors, and try adjusting your pci-e freq to either 99, 101 or 109 instead of the 110 as suggested. I would also say that having my c2d overclocked to a certain level is fine. If I clock it any further (even though it's stable with another card) then it will fall over. Return your chip to stock settings :)

Good luck and keep us upto date :)

Hi,

Just had a very similar problem with an SLI 650i board not wanting to run with a single card.

The fix was to go into the BIOS and load failsafe defaults, save and shutdown.

change card

Then all was well
