Ok I have no clue what this might be from. When I have my computer totally off then turn it on and start doing stuff on my computer it has like a little bit of lag. Like if i move the mouse round every 2 seconds it acts like it gets stuck and then continues. This happens with the games i play. It is like a constant ( as in happens every 2 secs) lag. Now if i restart my computer the lag goes away....... this wouldnt be such a big problem except when i restart it never recognizes that I have a disk drive anymore. So its like i get to choose, have lag, or have no disk drive. Can anyone help pinpoint what might be the cause of this. Thanks.
