Hi,

I am facing a very strange problem.My configuration is e6300@1.86,2GB Kingston DDR2 800Mhz ram,Intel DG965RY mainboard,windows XP SP2.

Earlier i was using XFX Geforce 7900 GT,but few maonths before the card started to malfanctioned.There was corruption in in-game graphics.Black triangles was appearing during gameplay.Later I was seeing various coloured dots on my desktop and after somtime the it started to get freezed.Therefore i planned to change my graphics card.

1 month ago i bought Palit radeon 4850 sonic special edition 512MB GDDR5 700/900 and a corsair 550watt vx series PSU.I installed both of them and the card started working nicely.After 2 days of installation i went outstation for a fortnight.After coming back I started my PC and strange white blocks started to come all over my desktop.I managed to see the windows logo and after that the windows desktop behind those white blocks.A message was there that VPU recover had reset the GPU as it had been failed to respond to driver commands.This happend every time i reboot and the system resstore also failed.Utterly confused,I formatted my hard disk and reinstalled windows XP.The problem was resolved and everything was running fine for 15 days or so and i was gaming for about 8 hours during those days.After that I went outstation again and after a fortnight when I returned, I found my PC in same malfunctioned condition.This time even at time of formatting the white blocks sustained and nothing seemed to solve the problem.Finally I reinserted the card at it's slot and that solved the problem.But I dont know when i will return after 15 days, will it work or not?What is happening?Is the card faulty or the pcie x16 slot?I dont know what to do.Please help..

Are you saying your leaving this machine on for extended periods of time? Check the cards temps and make sure you have decent case cooling. Not just one 80mm fan bout a could 120mm's would be good.

The corsair 550 is also not enough wattage for the card , but I wouldn't say that's the immediate cause. It's should still be changed to the 650 model in the near future.

Hi,

Thanks for your reply.previously i had gone through the official site of ATI technologies i.e. ati.amd.com.They have suggested Corsair vx 550 watt PSU for their 4850 and 4870 series of graphics cards.Keeping their suggestion in mind i had bought that PSU.So, right now i dont now, if i had been misinformed or not.

I had left my machine for 7 or 15 days and after that i tried to startup my pc and got those white blocks and other graphical corruptions.Under full load my GPU temperature is 64 to 65 degree C.Is it harmful for my machine?Please suggest..

70c should is the max a gpu SHOULD be getting. So 64 to 65 seems ok. See if you can borrow a 650 unit and give that a shot.
