It all started when I was playing Call of Duty 2 online where I started to get flickering on my pc screen. I thought nothing of it, until it became more frequent and then suddenly the game would freeze and I got a screen full of red dots and a black background :S. Whenever this happened I had to just switch my computer off by the tower. It then became a bigger problem because my desktop and everything on my PC Screen would be pixelated and very unclear. My computer automatically changed my resolution and color settings to LOW and would not let me change them any higher.
My first thoughts was that there was a problem with my Monitor but I asked many people and majority said it was my graphics card. So I took my PC apart removed the graphics card and let it cool down for a while. Put it back in and YES everything was back to normal.. until about 20 mins later. My PC froze and I had to had to switch it off at the tower again. Now I can't even get to the Windows XP login page where you put your password in, the screen just goes black and nothing happens.
At the moment im not really sure what it can be, I'm pretty sure its out of my monitor, gfx card, processor or my power supply. Also I checked my CPU Temperature and it was 55C, I have no idea if that's normal or not but something tells me that's a little hot. I didn't think the temp in my PC would be a problem because I have 4 fans
Can any of you tell me what my problem could be and how I could fix it?
Any solutions would be great, thanks alot.
