My 5850 came today, but problems are here.

chris_uk333 · 2 Jul 2010 at 00:20

Just turned my speakers on via the plug...Computer turned of. I tried to turn it back on, and it wouldn't...So i plugged it out of the wall and back in, and it booted...This is very odd.

Hey there, I don't think it's a power issue but its always good to make sure. Since soon after release, I have been running the 5850 and an overclocked q6600 on a coolermaster 460 with 2x18a 12v rails. What board is it you have?

chris_uk333 · 2 Jul 2010 at 00:58

Reset battery and I now can't get a picture on boot up...typing this on my iPod

cmndr_andi · 2 Jul 2010 at 01:00

Why did you reset the battery? not that it should have caused any problems if done right (with PSU or wall power off).

chris_uk333 · 2 Jul 2010 at 01:08

Just put the 4850 back in, works fine...I have no idea if it's the MB, GPU, PSU....I am...Stuck!

Motherboard is an Asus P5KPL AM

PSu? drawing too much power?

JTrickle · 2 Jul 2010 at 01:21

Cant see anything saying the 400w psu has been tested yet.

straxusii · 2 Jul 2010 at 07:16

If it works fine with your 4850 but not the 5850 then it's not the psu, and that psu should be fine to power the 5850. I havent updated my sig yet as I have a new psu but remove the 9600GT and all of that ran fine on the 500W psu.

So it's either a duff 5850 or an incompatibility, remove all the cards you can except the 5850, if it still happens it's a duff 5850 or it's incompatible with your m/b

I suggested you updated your m/b bios to latest, has this been done yet?

i had same problem with my old Gigabyte GA-MA790FXT-UD5P board. everytime i turn a wall plug on even in a different room,,, the system would reboot by it self.

what im thinking it could have been that the motherboard wasn't siting right...

Your mobo has onboard VGA, chances are that when you reset the BIOS you changed the primary display to Onboard. Plug your monitor into the onboard VGA then change it back to PCI-E or PEG

What do you mean by remove all cards except the 5850?

Also, where do i update my Bios? When i go to the Asus site and have a look, there's lots of updates...Do i just download them all?

EGuitarStar · 2 Jul 2010 at 13:25

Make sure all connections to devices, drives, HDDs, RAM etc... are all plugged in as they should be, even if they look fine just double check everything and push them into their places again.

One way to find out if it is a PSU power issue is to unplug/remove anything which you can do without, such as optical drive/s, external usb devices (ipods, phones, Ext HDDs etc..) any additional HDDs and try that.

Did you try my suggestion above because if its defaulting to onboard VGA this is why you arent getting a display from the 5850

Get the latest BIOS update for your motherboard. They should be dated with version numbers. Avoid flashing your BIOS via any Windows applications.

chris_uk333 · 2 Jul 2010 at 13:36

Ok just got the Bios update. It's just a ROM file, what do i do with it? (Sorry to be a noob) Also, i will try that Meatloaf.

Stanners · 2 Jul 2010 at 13:37

Did you try the 400watt PSU ?

Check the Asus site, it will provide you with clear instructions of how to update your BIOS and may provide tools to make it easier.

chris_uk333 · 2 Jul 2010 at 13:49

Cheers. I contacted OCUK, and they say...

Are you sure you are not overloading the PSU? 600W is not that powerful to be running a 5850?

Regards,

They are true with what they say, 600W is fine but then it also depends on whether you have anything overclocked, number of optical drives & HDDs, USB devices etc... these all require power too.

I would suggest you try it with the bare minimum required to get your machine running and just the 5850.
