Help! - Video Card or MoBo or WHAT?
My System - gigabyte GA965P-DS3 mobo, xfx geforce 7600gt, core 2 duo e7200, ocz pc2 6400 2gb (1gbx2) dual channel plat. rev. 2, antec case w/ 350w power
The Problem - worked fine for all gaming for nearly 2 years then 3 weeks ago graphics started having multicolor dots on black backgrounds with vertical elongations on some graphics. then 1 week ago while gaming it started having screen go black for few seconds then picture would return as normal. I thought my gpu might be failing. and finally today, the computer would turn on but the monitor says "no signal detected". video card, right? but why then can't i access the dvd drives and why does the reset button not work and I can't turn off the computer by holding down the power button as would normally work. I checked all connections, cleaned everything, and noted that all fans including cpu and gpu are working properly when it is turned on. I can't check the gpu in another computer because i have no access to one.
I'd really appreciate some help/advice..................thanks.
