I have an hp pavilion dv4 2112tu notebook, i5 430m , 3gb ram . I didn't have any problems with it since recently . since a couple of months , my laptop has been lagging and stuttering while both heavy and light tasks . Videos , music , games browsing everything stutters quite frequently . I've tried updating all drivers , bios , multiple virus checks , stopping any useless services and programs but to no avail .Also i would like to mention a strange behaviour , in the resource monitor , cpu freq is being listed as 100% while cpu usage under whatsoever task doesn't go beyond 30-50%. also a program , ex - firefox would be running normally , with it's cpu usage around 15-20 , then all of a sudden it wouldfall down to 2-3 and lagging starts . this would continue and after 3-4 reboots it'd get back to normal but after sometime the same starts again . Any Solutions ?
Thanks.
Thanks.
