just a wild guess, could be the 4 gbs are not identical like latency etc? or maybe you have exceeded the max installable capacity.

They are both PNY 4 GB they came together, and the max memory for my laptop is 8 GB so i should be fine

Might be the RAM itself, would not usually go for PNY ram. Kingston, Corsair, or Crucial.

Sounds like one of the RAM sticks may be the issue. I'd recommend Crucial RAM.
