Hello everybody,

I got a Laptop DELL N5110 , i7 , 6gb ram , GT525M
The thing is before everything was working perfectly, and few days ago games start to lag.
for example, I got the game BF2 that was working 100% on the MAX settings without any lags even for one sec, and now it`s like lagging for few sec and it continues to work softly, I mean every 20sec ~ its lagging a bit then stop.
and other games that was working perfectly even more terrible like BF3 or COD MW2 was working medium very good! now you even cant play.
and the computer NOT on Power saver.
btw the graphic card updated...
I even format the computer and the problem still exist.
Another thing, sometimes, in the begging of the start-up the computer beep 5 times with a short stop then again beeps 5 times till windows comes up, but that happen only maybe like once a week...

any suggestions? 🙁
