On 2019, I had an blue screen while playing SC4, which made me completely lose the hard drive I was using.
And now, I installed SC4 again and I had an blue screen again after 1 minute of gameplay! (Fortunately it didn't kill my hard drive)
I've made memory tests, tried updating my graphics card drives but STILL wasn't able to solve it.
By the way, here's my system specs
Intel Celeron E3400 2,6 Ghz
2GB RAM
Intel GMA 3100
Windows 7 64 bits
