This problem has got me foxed. My son's laptop remains slow; it has recently been checked clear of malware ( my inititial suspicion) in a previous thread:
That thread concluded with a factoy reset using the VAIO Recovery Utility and much improved general performance. I ran sfc /scannow and after 13 hours it reported no problems ! First question - is it usual for scannow to take so long?
I trimmed all the start-up programs to just AVG and disabled all the non-Mircrosoft Services using msconfig and removed a lot of the pre-installed applications. File fragmentation on the C: drive is 0%
I had to reinstall an updated network adapter driver in order to get on to the Internet. Also, I needed to install some 89 Priority XP updates and it's performance has now dropped off considerably. For example, it now takes 130 secs to populate the Add or Remove Programs box, whereas before it was about 30 secs. So I am still suspicious that something is corrupt.
I have also benchmarked the laptop using Fresh Diagnose and the CPU sticks out lie a sore thumb. For an Intel Celeron running at 1.5GHz, it is achieving only 146 MDIPS at whereas the expected score for a lower spec CPU running at 700 MHz is 1,943 MDIPS - well over 10 ten time more!
Now I may be reading too much into this benchmark comparison, but I would very much appreciate some expert advice on where to go next.
