my computer has been crashing on me alot recently....it just shuts down by itself then when i try to restart it i cant even get on desktop....i will still be in the retarting up mode....my screen will just be black....then it'll say that i have a disk errror or something....and it cannot read or something....ive been rebooting my computer several times just to get back on my desktop....only if i reboot it then everything will work fine....but im tired of rebooting it....loosing everything i have over and over again....i dont know how to use the recover/repair or whatever in the xp cd....i only see a recovery console but i dont know how to use that....i cant even hook up another hard drive cuzz when i do it'll say disk error....both of the hard drive's have OS's on them....when i hook up both of them to my primary i can get on my desktop with nothing on the secondary.... but if i put one in the primary and the secondary it'll just say disk error....i dont know why but my primary works only.... my secondary is ****ed up or something.... the only things that come to my mind is that my power supply is messed up or my motherboard is messed up or my computer is overheating thats causing it to shut down....i dont think its my electrical outlet thats shutting down my computer.... anyways how do i fix this??.. how do i prevent this from happening again??..
