Bad card or weak psu

Replaced a 6850 with a Sapphire r9 280. When trying to load a game I get a black screen and complete freeze. Tried drivers 14.4 and 14.9. PSU is an Antec 550 plus. Also noted is the idle temp is 0 which seems strange.

I have another rig with a 7870 with same psu no problems idles at 27 and 44 under load.

Other specs I 3 3250 running stock, sata hd, 8mb ram, 2 optical drives and 4 120 fans.

Any suggestions will be appreciated.

 

7870 and 280 power consumption is just about the same, maybe 15w give or take.

Probably bad card.

 

Try removing the old drivers with DDU in safemode

Then install new in normal mode

 

^^^ what he said

 

A weak PSU typically would typically make the PC shut off

Since you have another PC, you could try switching out the 7870 and 280

 

A computer randomly shutting off is almost always down to the PSU either being faulty or insufficient.

 

Yes it is but as you clearly didn't read OPS post as he said 'When trying to load a game I get a black screen and complete freeze' and Yxskaft suggested that a weak PSU would make the pc shutt off which the op is NOT having.

 

Thanks for replies. Why does card have no temp at idle? You can touch card and feel no heat. Fan running at lowest setting.

 

It sounds like a faulty gpu. I'd recommend trying it in another pc, if you can.

 

seconded, or even a faulty PCIE slot. if you have another even slower one, try it.

 

Reinstalled 6850 works fine idle temp 36 so slot ok. Going to take card back to Micro Center.

 

You need do a proper driver clean out when swapping cards - especially going to a new generation of card. Any remnant drivers from the 6850 may cause issues with the running of the new card.

So as suggested above, use DDU to uninstall the graphics drivers then reinstall the latest beta found at AMD. (I mean, why would you want to use 14.4 or 14.9 when AMD's latest is 15.3? )

 

I agree with MacT. I recently swapped a HD5850 with a HD7970, which is almost the same card.
Before I removed the 5850 I uninstalled the drivers and ran DDU in safemode. After this I turned of the PC and swapped the cards. After Windows loaded installed the latest drivers. I never had/have a single problem.
Your PSU is strong enough as long as it operates properly.

 

Insert the videocard in the other rig you have and check if it has the same behaviour. If it behaves like it should then the card is not at fault.

Do you overclock the card?

 

Bad HD. Replaced HD card works perfect. Don't overclock anything and 550 PSU sufficient.

 

i doubt it was the HD but rather the windows OS that was installed on it probably had lots of software installed and/or some undesirable software installed on the machine

try format the old drive and use as a data/backup drive at least then if the drive is ok you are not losing anything as it will still be used

glad you have got the card working though, happy gaming

 

That's a new one never heard of a bad hard drive causing those symptoms.Did you install windows again when you replaced the hard drive?
