Is it blue screening or just shutting off?
If it is just shutting off then it could be a faulty power supply, but if its blue screening i think it might be the windows install. If it is the windows then i suggest re installing it.
I really recommend the phanteks eclipse p400s. It is around $100 CAD and comes with tempered glass and a rgb strip along with the synced rgb power bytton and lighting at the bottom.
