i have a HP Elitebook 8460p, 4 GB RAM, HD intel graphics 3000
everything on the laptop ran smoothly and very good, until 2 weeks ago it started to lag really badly. I tried everything, i have latest driver updates, no maleware, spyware or virus on the laptop, i ran diskcleaners, i cleaned the fan, i defragmented etc. etc, nothing helped, do you have any ideas what else i could try ?
thank you in advance
