I have an Vaio Vpcea23fb ( Core i3 4GB 500GB Win7 64 bits). It suddenly started to report problems in the registry, and several drivers reported problems. I reinstalled some drivers, and they are working fine, except for (Marvell Yukon 88E8059 PCI-E Gigabit Ethernet Controller), and so I can't use a cable for internet. I tried to unistall and reinstall it, but this is not working.
Sometimes, when loading windows, it tries to fix automatically some problems (that strange screen that tells you it's impossible to stop the process of recovering). And then, it starts after some minutes, very slow. IE is also stopping all the time (although I always always chrome).
Avast, Malwarebytes and CCleaner are not reporting prolems.
Thank you for your help,
