Samsung Laptop Running Slow

[callumm]

Hi, my New Samsung Laptop is running alot slower than before, it was running nice and fast then all of a sudden the next time I started it up it was ALOT slower
Laptop Specs
- 2.30 ghz (Intel i3-2350M)
- 6 GB RAM
Let me know if you need any more info on the Specs.
Anyway, I only installed a a small game and now its running slower, but i have installed games before and they didnt make much difference. I ran a Full Scan on Norton and there was no Viruses. Im so confused. Ive tried Cleaning Up my Computer too.
Thanks

I forgot to say that when I log on the Screen goes black for about 5 seconds with the just the mouse pointer.

If you're still running the factory pre-installed Win7 then I'd Clean Up Factory Bloatware.

If that doesn't help enough work through these Troubleshooting Steps for Windows 7
