Aero problems

Hello everyone, This seems to be my first post on this forum but i have no idea where else to look for support.

I am having problems with Aero, When i enable it a get a Blue screen of death saying "BAD_POOLER_CALL" not the exact second but about 30 minutes later or so.

I have the right drivers, I've installed the drivers for Win7 64-bit, Windows Vista 64-bit, But nothing seems to help whatsoever.

I have a new PC that used to have Vista, and i have Windows 7 X64 Ultimate.

I have a Gateway M-1631U, 4GB RAM, ATI Radeon X1270, AMD Turion 2.0 GHz Processor (Dual-Core).

Also, Aero ran fine on Vista, But on Windows 7, No.

I don't have any viruses because this happened on a clean install of Windows 7, Can anyone help me?

Thanks in advance,
