My new laptop comes with an Intel I7 chip and Windows 8. My 4 year old laptop has whatever and runs Windows XP. Have been to a number of sites to test download/upload speeds for each machine. Without exception the old machine runs 4 to 5 times faster than my new laptop. Have run a couple of programs to find viruses and malware. All these show that the new machine is clean.
At my wits end as to what to do next
