My very old but workable computer will continuously freeze on the user sign in page. The keyboard and mouse will freeze as well. The only thing i can do is turn off the computer, and again upon startup it will get to my password on the user sign in and freeze. I want to fix this problem to try and sell it for someone that needs a decent computer...Im thinking it may be the video card? Emachines t3256 512 Ram Windows XP NVIDIA GEforce4 gx graphics

Does this happen for all user accounts? Does it happen if you boot into Safe Mode and login with your regular account? What makes you think it's the video card? "So won’t you give this man his wings What a shame To have to beg you to see We’re not all the same What a shame" - Shinedown

Basically its as soon as i start up the computer it goes to the user sign in and freezes. It will not allow me to switch users or anything. The keyboard also freezes and i know this due to the caps or number locks not working. Im guessing the video card just becuase i have had trouble with it before. Its damn annoying.

"Im guessing the video card just because i have had trouble with it before." Like what kind of trouble? I suggest you get the power supply replaced before you sell it (the computer is probably not even worth that much anyway). EMachines are built with very cheap power supplies from a manufacturer called Bestec. Bestec makes about the worst power supplies around. They are made up of cheap capacitors and parts. I suggest that you get the power supply replaced ASAP because if it blows, it usually blows out the motherboard with it. Even if the power supply isn't the culprit for the freeze-ups, get it replaced anyway because it still could blow at anytime. Replace with a micro-atx power supply with a maximum load of 350W at the minimum. After you get that replaced and you find that it still freezes, boot it up into the BIOS and let it sit there for awhile. Does it freeze? If so, run Memtest86+ on the system for 12-24 hours.
