Well it started awhile back when my PSU died so I got a new better one, but the computer would still turn on but stay at a blank screen. I tested my parts and came to the conclusion that it was either my mobo or CPU or both, so I went to the store and got a new Asus mobo and a sempron chip and installed them. The computer still has the same problem and I don't know why and what to do. Sorry for my english and any help is much appreciated. Please use descriptive thread titles from now on.Thanks.
