My parents got a compaq presario ( i dont know what model) with a k6-2 500 mhz, 64mb ram. 10+ hd, etc. The computer came with internet service (AT&T AtHome) through a cable modem. Every time they logon it locks up for about 5-10 min. Same thing when they try to logoff. Also, they have not been able to turn off the computer properly. They have had the following probs: goes black, comes back on, goes black, comes back on; or freez up solid; or throw some weird error out. I cannot get down there until sunday to check it out, so I wanna ask you guys if you have any ideas as to how to solve either of these problems. My parents said the the powering off issue did not occur until the cable modem, software, and configuration was all done and installed.

Any ideas?
