Hello, I built my first computer about 3 months ago. It consisted of an AMD 3500, nvidia 7800gt, 1 gig value select corsair ram, and an asus a8n-e motherboad. I have ran into many problems such as having to RMA ram and video card fans go bad. For once it is working fine, but with my luck something else happened. I was doing homework and it was running fine, but then the screen just went blank. I restarted and there was 5 quick beeps from the motherboard and now it doesnt post. I searched for solutions, removed hardware and reseated them with no success. Can anyone help me find out what the problem is? All I want is a stable reliable computer.
