Dell Inspiron Windows XP, that I have given to my grandson (he lives with me and is 11 years old). The other evening, while he was playing Roblox and was on Skype, programs just started not responding. He couldn't shut down (control / alt / delete didn't work either) so he unplugged the machine. The following morning the machine booted up what looked to be just fine. Then realized that none of the programs responded. Icon double click or right click open. Again control / alt/ delete didn't work or shut down. Manually shutting down worked. Tried to start in safe mode with networking and it would not let me. Kept coming back to the screen with the three paragraphs of possible problem scenarios. Highlighted was start windows normally. I chose to start at last known good configuration and was able to do that. The PC worked for a while, then the sound went off. Then the programs stopped responding. At one point, (there were so many of them, I can't think of which time) I was able to do a malware bytes on my husband's user profile and it did find a few trojans. My user profile just opens to my background picture....no icons...nothing else. Do you think that this may be a virus? This morning it opens nicely, but again won't even let me into control panel.
Today, on my husband's profile, everything locked up when I did start/ settings/ control panel. After about 15 minutes, everything but the background disappeared (all icons etc)/
