I am having trouble running Oblivion on Windows Vista. My computer is definitely fast enough to run it, but whenever I go to start a new game, it freezes and I have to open task manager to close it. Has anybody else had this issue? If so, how might I fix this?

Tell us about your hardware configuration: computer brand and model, or motherboard, cpu, video graphics card, memory version installed, and how many GB - Memory brand or model if possible.

Mfg. and model: Medion MS-7237
OS: Windows Vista Home Premium, 32-bit
CPU: AMD Athlon 64 x2 Dual Core 5000+ CPU (2.3 GHz)
RAM: 2 GB (unknown type)
GFX card: NVIDIA GeForce 9600 GSO

Your RAM is probably key to resolving this problem... The fact that it is an unknown type raises red flags. Tell us more.
