Okay here it is - a friend of mine has a pc running windows 98 (I think/thats what he told me at least), it was a build your own done by a friend of his. Yes, I know thats where the problem(s) start. Well a few weeks ago, it started "rebooting" about every half hour or so - unwanted restarts. I'm new to this so I'm asking questions. Something tells me its either the OS or a driver that has an issue. This mod was build only for gaming. I'd like to avoid having to re-install Windows on it because I don't think he has the disks any more and it might be too old for Windows XP. Any suggestions on where to begin and/or fixes are greatly appreciated. I'll have him make sure all the cables are firmly pulled in and in the right places. Thank you so very much.
