1-) Post your system specs. This is a tremondous help and a necessary information for us to help you out. I wil post my specs.
CPU: P7350
RAM: 4g DDR2 800MHZ (don't need to be that specific)
HD: 320g
Graphics Card: HD 4670m 512mb
monitor/resolution: since it's a notebook I don't know the manufacturer/ 1366*768
OS: Windows 7 64 bit (it needs to be that specific)
I don't know how to do it! Don't fret you can go to Computer and click there with the right button and then click properties in the drop down menu. There you will find the device manager and in that you will find the information.
No can do! go for the run (or for people with 7 and vista the windows menu) and type dxdiag. Run it and please copy only the info shown here!
