I was on the internet on my main computer and i started to smell something like plastic burning so i turned it off right away. I went to look and i saw smoke but i dont know from were. I kept it off for a while then turned it back on and went to the bios. My cpus temp was 44 but i started to smell it again so i truned it off. The only thing i did to the comp today was put some plastic tubing on and did some wire management. The xp 2400+ is overclocked to at 2.25 ghz for a week or two and never smelled anything. Im scared to turn on the comp rite now. I dont now what it can be.
