Buying a Compaq Presario C700 on Ebay...I have already purchased the item, which was advertised as having 2+Ghz processor, and indeed the screen shot seems to show this. But when I looked up the same machine online it was stated as having about 1.4GHz. Does this mean it's upgraded, or overclocked? If the latter, it must run hot. As a second question, is it possible to obtain a cooling software that actually controls cpu usage?? Thanks for help!
