Hello everyone, I've recently put together my first gaming PC and I haven't had any serious issues except for my PSU making a weird rattling noise that seems to persist randomly after two days or so. I have a good feeling that it may have something to do with Power Supply as I noticed that my FPS dropped significantly from 60fps+ to 30fps and under however, It has been always keeping up at 60fps+ even with the PSU noise coming back randomly...until i installed The Elder Scrolls Oblivion. (I don't know if this has anything to do with my performance but I noticed after ending that game and going to a game I'd normally play in that schedule which was boarderlands2 the fps was at 30fps) I'd love to start playing again but I don't know what the problem is coming from. Please help I'll try all troubleshooting methods. Right now I'm currently in the process of reinstalling Windows 10 a clean install by formatting HDD. I never had this issue before and have no idea what may have caused it as the only thing i did was download a game and play it and switch to another one and fps drops on any game i switch to now. Here's my PC specs if that helps.. http://pcpartpicker.com/list/XCXGjc I don't have the GPU as shown yet, I'm using intel HD 530 graphics and never had an issue with framerate until now.
