What could cause this?

[Coolty44]

So, recently, I got a new computer and I love it, regardless of the fact I had no choice in the matter (present).

But there is currently one problem I have with it. Every time I start a game, normally 15 mins or when something changes rapidly, the game starts to lag horribly. Now, I know it's not the game, since I've tried 4 different games, and only 3 work properly (Warcraft, Portal, and Alien Swarm don't, Spore does)

My computer is a HP Pavilion dv7 with Windows 7 home Premium. Anything that could be causing this?

Wait, so Warcraft, Portal, and Alien Swarm, all work properly, and spore is the one that lags?

 

[Coolty44]

No, Warcraft, Portal and Alien Swarm do not work properly and lag, well spore does not lag, I probably should have worded that better.

Make sure that all your video drivers are up to date, and working. I'm hoping that you have Windows 32 bit.

I have 64 bit... And I suppose that could be a problem?

 

[Gilles]

It said it couldn't find a driver for 64 bit... you'll have to find the driver yourself then.

Well 64-Bit causes graphic problems like your screen is 3/4, so you'll have to edit the registry to change resolution, but 1st of all you'll need to find the drivers.

You can try to use Driver Genius, it can update your stuff, but you'll have to torrent it as I'm sure you don't want to pay.

I won't give link as it's against the rules.
