On Wednesday, my brother came downstairs and said that his computer had crashed while he was on the internet, (dirty websites, i think), and when he trys and turns it on, it won't let him log in.So I went to take a look, since I understand computers more than anyone else in my family, and the computer kept on rebooting itself at the login stage after 4 seconds of being on it. I went on towww.ijinni.com and asked there advice and they said to try accessing the computer through safe mode with networking, but I didnt get a chance to that night.Tonight I eventually got a chance to try doing so, and when I try and access the computer through safe mode with networking, another page appears sayingPlease select the operating system to start: Microsoft Windows XP ProfessionalI selected this one, as it is the only one available and is the system that the computer runs on, however after doing this, the computer goes through the same similar processes at load up. e.g. dell load screen, windows xp load screen, then login in stage. When it got to the login stage, the computer rebooted itself again, meaning that I cannot even access the computer through safe mode.PLEASE CAN YOU TELL ME WHAT I CAN DO TO SOLVE THIS PROBLEM, AND WHAT THE PROBLEM IS!!!1 person got this answerI do too
