I have been upgrading my computer slowly but surely. And i have just replaced my graphics card.
however its seems like i am not getting a very good performance from it. everything just seems out from my old car. Like i just ran Counter Strike: Source to see what it would be like and i have lines going down and screen and such.
MSI NVIDIA GT 440 LP Graphics Card 1GB - Link
MSI GeForce GTX 560Ti 448 Twin Frozr III Power Edition / OC 1280MB GDDR5 - Link
Also think i should uninstall all other graphical drivers. as my old card ones are still on here? but i cant see it making much of a difference.
The ModXStream OCZ PSUs are prone to failure. What you are seeing are probably artifacts caused by the graphics card due to out of spec voltage on the 12V rail. Check your voltage with a PSU tester or multimeter. If you don't have either of those or do not know how to use a multimeter, swap the PSU out with a friend's PSU of the appropriate wattage for testing purposes.
Make sure you have the latest drivers, but I am almost certain you are having a hardware failure.
Was your old drivers manufacturer's drivers or nVidia's drivers? Manufacturers will make tweaks and adjustments to the stock drivers supplied by nVidia. Those adjustments may not work with your new card.
