I recently purchased a AMD 3000+ and installed it myself onto my ecs k7s5a motherboard. It booted fine and things were running fine for a while but now it's constantly freezing. I've also noticed that my case has smoke coming out of the holes in the back. I have no case fans in this case and I had a hard time installing the cpu to this motherboard so I had to disassemble the cpu cooler and the fan was completely taken off. Could this cause over heating?? I tried a burn in test to fix it, but it seemed to make things worse. Is it normal to have sparks come off of the cpu every time the computer starts up? I am very new to this overclocking ordeal. Thank you very much for your time. I hope I haven't mangled my pc too bad.
