Question PC Crashes when Gaming

[vrh2373]

Hello, I have an old compaq PC from 2006. I have recently installed Windows 7 and when gaming, PC crashes at around 7 or 8 minutes of gaming. I've already did a FurMark test to see if it would crash, but FurMark doesn't crash my PC. I've stressed CPU, RAM, GPU and nothing crashes the PC, only games do. Any ideas why it crashes?

Edit: Forgot this was running Windows 10 before and when gaming crashes did not occur.

Maybe compatibility issues or your computer somehow knows it's a windows 10 originally?
