Hi, I have bought my computer like this. The thing is I cleaned it out free of sypware or adware or viruses. Now I checked the harddrive and the memory that came out good. The computer always runs on a high temperature I check the fan temp and it is high. I checked the fans to see if they are spinning right, tight and they seem to be working right. I have a hewlit packard pavillion a620n. I hope you can help thanks.
