Specs are :
Intel:Pentium(lol)
RAM:4 GB
Nvidia:GForce GT430
Yep these are my specs :p
But it used to run ksp pretty good before i put an old graphics card that i listed here and the pc pretty much started crashing!
This is because of the psu
If the psu cant handle the power intake the pc crashes and it does not show a Blue screen
Hope this helps
