I have a HP Pavilion a400y computer. I has 500 mb or memory. The computer is extremely slow lately. I, on a daily basis, delete temporary files, history, trash in emails, and recycle bin. It is ok for a brief while then slow down almost to a freeze. I was told that I had too may programs in my startup. I don't know what is necessary and currently have the following: RECGUARD, sgtray, KED, hpgs@wnd, hpqSrmon, Reader_sl, qttask, rundll32. This group was what I was told I needed by a HP tech. I haven't faintest idea what they all stand for. What is actually needed? Thank you, thumudom
