Intel 2.8 Ghz Pentium D
Graphics card: NVIDIA GeForce 9600 GT
2 GB of ram - not sure how to tell what type. Is that "seriously low"?
Windows 7 (I always forget if it's 64-bit or 32. Computer is currently fried - having the doc take a look at it tomorrow.)
........your ram count is low by todays standards for sure but the experience you're describing makes me think you didn't install the correct video card drivers and it's running on integrated graphics.....you should install the 64-bit version of windows since your CPU is 64-bit........
