Packard Bell Sj 51 unstable

[shawns]

I bought this laptop a while ago. There was already Windows 7 installed on it and running perfectly.

I was dumb and decided to install a new fresh copy of win 7 on it without backing up the drivers.

After the install i didnt know where to find the drivers , so i googled and downloaded them from a site called driverscollection , but those were not the correct ones (they were for this model but some of them were for Vista , XP and windows 7.

Now the laptop is running really unstable , i got alot of BSODS but then i updated the bios and bsod problem solved.

Still its really unstable ,

First i installed drivers with DriverGenius
It was still unstable , then i decided to install Windows 7 again and only use drivers provided from Windows update. Still unstable.

The last time i decided to install from driverscollection , problem still not resolved.

One of the signs is that for example if i am browsing a page , when i scroll down its kind of laggy . If i have a youtube video playing in the background the computer gets really laggy and sometimes even freezez.

I think these issues are due to incorrect drivers etc but i am not getting any yellow triangles in the device manager.

What do you guys think can be the problem?
