I am new to this forum, i registered since i couldnt manage to get the problem fixed by talking to the reseller or to swedish forums.
I have tried these different PSU:s:
Corsair TX 650w
XFX Pro Series 850w
Fractal Design Newton r2 1000w
Cougar CM 1000w
And i've got this horrible coil whine whenever i run a benchmarking program,
starting a game and comes to the menu screen, and also when the fps is high. I got the problem fixed by turning v-sync on, but since im using crossfire and since i've always played without v-sync (and wants to keep on doing it)
this is not an acceptable solution for me.
I have also tried to change keyboard, mice and also switched to a SSD hard drive instead of the old mechanic ones, and the problem is still there.
I have also switched graphic cards from:
GTX 470 (another one)
And the problem has been there with all these different graphics card.
I have also tried the computer at friends houses to see if the problem was in the connection into the computer, but no, sampe problem no matter where i run it from. I have also tried to run it outside the case and in a different case and the problem is still there. I have also changed the memory sticks.
The only thing i havent changed is the motherboard, but is it really that big of a chance that the motherboard is causing all this?
This is my rig for the moment:
4GB ram (Corsair)
Cougar CM 1000w
If i ever find a solution to this problem i will personally give the guy who helps me fixes this a gift, the gift is my steam account with Black ops, MW2 and some other really cool games (which i dont like to play anymore).
Thanks for any answers that can help me and have a great day.
