Hey guys so I am running starcraft 2 and it works fine when I start a game but once there are a lot of units on the maps it freezes up the screen and i can almost not move at all.
Here are my system specs:
Motherboard: ACPI x64-based PC
Processor: AMD Phenomâ„¢ 9500 Quad-Core
RAM: 8GB - PC2 6400 2GB cards x4
Graphics Card:NVIDIA GeForce 9400 GT
Hard Drive: 1TB - Hitachi HDT721010SLA360 ATA
Power Supply: Ultra LSP 550W ATX
Also having problems with HD Video editing. I am wondering whether it was my video card or processor or something else that is causing the problem and whether i can upgrade it or not.
Look forward to hearing from you guys!
Thanks
