Desktop PC erractic start up and freezing once loaded?
Switch on front only works occasionally but then computer freezes a few minutes after loading windows. Sometimes when switching on the orange light comes on, the fan goes into overdrive but computer does not load. Is something loose since tilting the box sometimes restarts the PC?
DELL Dimension 4700
i had the same problem with my pc, what i found worked with mine was, i unpluged the whole computer from the sockets and left it for 24 hours, when i rebooted the next day everything was fine, hope this works for you aswell.
