Blue Screen Error...

Since our computer been fixed? i felt that it getting worst right now. Our computer dont have virus anymore but i am wondering why the blue screen always showed up and say the files are corrupted or something. Then it said there is a file that is not installed property and i need to disable something but i dont know what. I try to check it at control panel and check some of the files that we installed but i never seen any files that is not installed properly. I dont know what to do, its very frustrating everytime the blue screen showed up. This morning, i think the blue screen showed up 4 times so i restart the computer 4 times also. Isn't that frustrating? Well hopefully i can find that corrupted files so that i can delete it and wont show the blue screen again.
