Hello all,

I've got a problem with my computer and after calling around and asking everybody i know i still haven't got any real solution to my problem.

I recently moved my computer from one house to another. after the move I decided to move up my GPU up one slot so it would have better room to blow out hot air (my HD 6970 CU II) was getting a little hotter than usual. After moving it up one slot my GPU would overheat instantly when gaming or doing any other intensive task. I sent it back for RMA after wich they teste(105-115 Celsius)d it and told me they found no faults with it and the temperatures where perfectly normal.

So I am at a complete loss here right now, My GPU is on it's way back now but after calling with the tech support guy he told it me it could possibly be my PSU. Im also using another GPU(4870x2) right now(an older one) and at one PCI-e slot it overheats instantly and at the other PCI-E slot it slowly goes op to 80-90 Celsius(now if i remember correctly i replaced my 4870x2 with the 6970 CU II because it overheated). So with no other parts that i can test it with i really don't know where the problem could be.

All the other temperatures on my PC are normal. it's really just the GPU overheating. could it be that the PCI-E lanes are faulty or that the PSU is failing. The motherboard is a ASUS P6T SE, the PSU a cooler master 850watt. CPU is a i7 920 and I have 12GB of ram in it.

Can any of you guys make any sense out of this? I'm really frustrated about it and i'm just thinking about upgrading everything and get rid of the mobo,cpu and psu.


Update: I deleted the drivers of my (faulty)4870x2 with driver sweeper. Put it in another pci-e slot to check if one was faulty. At start up windows installed the drivers (VGA, HMDI AUDIO and another one) but when i used the other PCI-E lane it also installed drivers for PCI to PCI drivers. I'm really puzzled by all this...
