I recently built a computer and im very frustrated with it so far. Ive been having some issues but the biggest issue now is that my computer locks up (cant ctrl+alt+del and just shows the loading cursor) all the time sometimes randomly and every single time I try and start a game (i.e TF2 and COD4) When it locks up I notice that some things look strange like im getting lines across the screen and weird colors in some areas. After it sits on this screen for about 5 minutes or so the "blue screen" comes up. I was using powerstrip overclocking program but i removed it to try and troubleshoot. What is causing this? Can anyone help me? All my parts are currently listed below. I have the newest GPU drivers. i do thank everyone in advance for helping me with this issue. I really need help.
EDIT: I just tried swapping out RAM and that did not fix the problem. Keep in mind these are all brand new parts.
