Hello & Welcome.
Try to be specific on your problem? How do you crash? Do the BSOD happen only while gaming?
First make sure that all of your drivers are up to date, then do a complete test on your rig, run Prime 95 for stability, Furmark for GPU test and some other benchmark softwares to make sure nothing wrong in your components.
Then make sure that your RAM timings are correct in BIOS, run Memtest 86 and see if it reports any errors.
