I was on my computer the other day surfing the net and my screen just went blank for no reason and my monitor displayed an error saying that it has lost connection but the computer was still running. I restarted the computer using the power button and it was fine, so I went on a game and after like 5 minutes the computer blue screened. I thought that my graphics card has come out of it's slot so I took it out and put it back in. I started the computer but I couldn't get a display. I thought I fried my graphics card so I put my old 9600 GS in and I still get any display. So I assume maybe it is something to do with motherboard.
Because I got the PC from PC World I took it back to them since it was still under the warranty. They have had the PC for over a month now and they still haven't diagnosed it. They probably have the worst customer service, they keep on lying to me about when they will fix it. I was thinking of taking it back and fixing it myself because I've had enough of waiting.
I just wanted to know if this is a motherboard problem and if it is what motherboards will fit on my system.
This is my current motherboard/computer: Core - Diego S Motherboard - spec_diego_s - Information and Instructions - IXTREME X9610 - PB81X14901 - iXtreme - platform_amadeus_ixtreme - Desktop
Sorry for making this long, and thanks in advance.
