os>xp>sp3: my relatives pc was working fine on wed.morning/afternoon. turned it on thur morn & got a message on desktop "dcom service has a problem, pc needs to restart". restarted & got another message saying " since windows was first activated, hardware on pc as changed significantly.due to these changes, windows must be reactivated in 3 days, do you want to reactivate now?. the only hardware change involved installing an exact duplicate intel motherboard 2 months ago. no problems there, didn't have to reformat. been running fine. when pc restarted , the green start menu button reverted to classic menu. changed it back & lost the my doc, network, & my computer icons, but reappeared when i switched back. i can open firefox but can't surf. can't open ie, or mbam, or mcafee virus/firewall app. ran sas but nothing came up. when i open network icon to view connections, the page is blank, nothing showing. the led lights are working on back of pc. ran "ping 127.0.0.1 from command prompt & no packets were lost. wonder if network card is bad though. pc is 4 or 5 yrs old. when i right click on any service & click properties, nothing happens. same thing happens when i check the network adapter in device mgr. can't open xp sys restore, message saying " sys restore is not protected, need to restart pc". i have geswall security app installed & tried to open it & message says " it has expired, needs to be updated", but no new version is out. tried to uninstall geswall, but new message says" windows installer is not working". in services its set to manual. never had a problem with it. i know malware can get in through sys restore, but i would think that hopefully mcafee & geswall would've prevented something from installing. i manually updated windows xp updates on monday, & i've read before that some updates can cause problems.i hooked my own pc up to type this. we have router but haven't had time to set it up. i've been switching pc's back in forth for awhile now,so i doubt that unhooking her pc would cause any problems. i have an xp cd with my pc, but i don't want to have to reformat. i'm not real pc savy, but is there something i could run from a command prompt to check or repair? what would i go to if i have to boot from the xp cd in order to try a fix that way? i guess i need to know what caused it in the first place in order to find a solution. I'm at a lost here. SORRY for the long post. THANX for your time/help anyone.
