Strange Problem

I am running a Intel 1.6 gig,on a Soyo Dragon plus MB,with 256k of DDram.Recently,my cd burner started locking up at the beginning of a burn.The burner checks good in another pc.Now,sometimes when I type in characters in the address bar,they start actually showing up a few seconds later,kinda like a time delay.My bios health system program shows my cpu temp at approx.43 degrees Celcius,under a light load.I have the case cover off,and 4 seperate cooling fans running,but the computer room is a little warm sometimes,compared to the rest of the house. Would a cpu running warm display these symptoms? I dont recall having these symptoms until the weather started warming up outside,but I am really not sure what is happening,as I have never had an overheat problem before..Thanks for any suggestions.. 

If ya don't ask..How ya gonna know.
