Leadtek GTX260 EXTREME+ PROBLEMS PLEASE HELP!

hey guys,

i recently bought a winfast leadtek GTX260 EXTREME+ to replace my Asus 8800GT. well all i can say is that i wish i could get my 8800gt bak from my friend who i sold it to because im getting problems (video problems). When i surf the internet or jst leave it idle its fine but when i start to play some games well depending on the games if its weak like warcraft 3 nothing happens but when i start to run something more powerful like company of heroes the video just dies after 15 - 30 mins.

The display on my screen goes all colourful (pink yellow orange green purple so on) and has these weird lines from left to right top to bottom. iv had this problem many times when i played company of heroes on these past few days and due to this my comp freezes and crashes which i have to restart.

my comp specs are
Q6600@ 3.2GHz
2GB 800 ram
Asus P5N-D
750 corsiar power supply
Antec P180 case
500GB samsung hard drive 7200rpm
500GB seagate hard drive 7200rpm
Leadtek GTX260 Ex + (use to be Asus 8800GT)

yer okai ill check on that now..

all my games are patched up to date. =[

oh btw i uploaded one of the pics as my avatar i hope that helps. =[

thats wat it looks like, all weird ass colours, lines and shapes

Are you using the trainer file? You know the cheat file because I think that has something to do with the weird colors. I know this from my own experience with the trainer file and I also use the GTX 260.

Oh wells nvm im planning to get a refund now there they are gonna charge me 10% of $315 for re-instock fee how lame. =[ Cant be bothered to get warranty have wait 2 weeks for them to send it to leadtek.

wells im planning to go bak to using Asus i was thinking should i get a GTX260 again or should i get GTX275 but i am going to SLI it so i need some help to see if my power supply can handle sli GTX275 along with everything else.

If not im just gonna get SLI GTX260, well i hope Asus have the core 216 not the 192. If anyone can tell me this would be great help.

Anyones help is much appreciated.
