Brand new parts, and I just finished building it today, but when I turn it on, it lights up (all the fans start moving and whatnot), but after awhile everything will go dark, the fans will stop, and then everything picks back up again. This seems to be continuously happening with no consistent time interval between shut-offs and turn-ons.
On top of this, when I plug it into my monitor (which I've used only a couple days ago on a different computer) and turn it on, nothing happens. I've tried all the simple suggestions I've seen on other posts, like moving the memory around and making sure everything's plugged in tight, but no luck there.
This is my first post here so if I'm doing something wrong please tell me. Any suggestions with regards to my predicament would be greatly appreciated. I'll try to include any necessary component information below. Thanks a lot.
