Thanks for the reply guys.
@ Influx apart from avast all are on demand. I installed kingsoft a couple of month ago just for testing, its good but i guess i don't need it i will uninstall it no problem. But MBAM and hitman has been in the system from very long time they should not cause any problem. Where can i find GFX card driver update? I tried to update display adapter driver but windows reported that its up to date.
Is there a way to pin piont the root of the problem?
Many many thanks again
