Hi,
Well my principal laptop is an hold P4 1,7ghz with 1Go memory, 169go HDD, DVD DL burner with XP Pro SP2
I repair an hold Eeepc 900, installing XP PRO SP3 2go memory wit old Asus SSD.
Same thing, it's working fine, no freeze, no decrease capacity of memory and screen problem.
All avast webrep installed on IE8 and Firefox, and i don't use outlook too.
This version is more stable than previous, no shut-down memory or screen bad effect.
Maybe disable plugin, to avoid problem.
Need more fix for other OS than Xp which is the oldest os too...
