Laptop lagging massivly after reinstalling OS.

[iClutch]

So, i wanted to reinstall my Windows 7 Home Premium on my lapotop, which i did without problem (clean install).
But the problem was that when i booted into Windows 7, i first tried to open Internet Explorer, but it tookk about 30 secs to open it, so i tought "WTH? Why are you so slow?"

So i ran the Windows Experience Index, and i had 1.0 on both of the graphics indexes.
Now im so confused, this computer ran with Windows 7 Home Prem just perfectly before :/

Any solutions?

CPU: AMD E-450 APU with Radeon HD Graphics 1.65 GHz

RAM: DDR3 4GB

Did you install the chipset drivers? Check your device manager. If any items have a yellow exclamation point next to them, then they require drivers to be installed.

I checked the device manager and the only thing that had the yellow warning thingy was the networking device, and windows can't find an update for it.
But i don't think that updating the network driver will help.

I also tried updating the processor drivers, an update was found, but it was only somekind of security update for x64 CPU's :/

Try opening a game Chess (perhaps already present on Win7 HP). If it says something like "Hardware acceleration disabled" then you should install the graphics drivers. Download the drivers from amd.com.

Solved, the problem was with the RAM, the contacts of the RAM were burned so i got them replaced, works fine now.
