Question I did a case swap, but now PC crashes sometimes on startup

[MarkT3001]

CPU: i7 3770k 3.50GHz
RAM: 16GB Corsair Vengeance
Motherboard: Asrock B75 Pro3-M
Hard Drive: 1TB Seagate 7200rpm
Windows 10 64bit
GPU: Saphire Dual X AMD R9 200 series
Corsair 500watt CX PSU
Samsung Blu ray drive
Corsair 88R Carbide Micro ATX case

I had put all of these components (apart from the Corsair case) into an old Compaq Presario case a number of years ago and everything generally worked except on games. Then when I started to play games on the system I found out the poor air cooling was probably causing games to crash. So I swapped to a Corsair Carbide 88R micro ATX case. Then as soon as I booted up the computer would freeze on the loading screen. What has happened if everything worked in the old case?

How old is that PSU? You should be having a PSU that is at least 550W(or more) for the sake of longevity. I'm assuming that the PSU is as old as the platform and as such is incapable of delivering the necessary power to the entire system.

I second this. Sounds like a PSU issue

The PSU is pretty old, at least as old as the motherboard, it is powering 3 larger 120mm fans in the new case, the old case only had 1 92mm fan.
