i bought an Asus EN8600GT Silent video card with 256mb of DDR3RAM on it, and installed it in my computer along with another Gb of RAM, and a new Power supply. The video card blowed big time, hung up for two or three seconds, and would not run my games worth a flip. I had a ATI Radeon 1700SE w/528mb of ram in there, and have since put it back in my computer. But My game still acts quarky! My ram is composed of 2 sticks of 1 Gb, and 2 - 528Mb sticks. One of the gigabyte sticks is a Corsair, and the other is Samsung. Could this be an issue. The guy at the electronics store said it didn't matter.
I've done all the cleaning, and spyware checking, defraging, etc..looked at startup processes. Nothing has changed since before I done the upgrade. Any ideas?
