HiMy friend has asked me to help him fix his PC which was working OK when his daughter inserted her flash drive and it all went blank.It was running Windowns XP and was protected with AVG Free AntiVirus, superantispyware Free and Spybot, but I'm not sure if he kept them all up to date!When it now turns on the BIOS countdown does not finish and freezes. No keys work on the keyboard.It stops at "Memory runs at single channel"Even pressing "Del" to enter setup will not let the bios load any furhter even after a restart with the power button.Your suggestions would be much appreciated.Thank youF9 for express recovery does not work either.
keep tapping F8 as the computer starts to get into safe mode.If you get in maybe a system restore or last good configuration might hep.
but f8 will only usually work once this POST has finished, and this is not the case here.Sorry, I may not have made this clear in my post.Thanks again..
Looks like one of your memory sticks has a problem.For dual channel both sticks need to be identical if one has a fault then this could case the message and BIOS problem.Remove one memory stick at a time and see if you can get it to boot.
if that is no go. Take out the cmos battery for 30seconds, to reset cmos and then try.If no go there. Strip down the inards to the bare minimum and try.
I took all 4 memory sticks out and tried them all individually in all 4 slots one at a time but that did not work.I left one memory stick in.Then I took the cmos battery out and waited 30 seconds and that worked - to a degree.It now finds the hard drive, etc but I get an error message telling me thar NTLDR is missing and to presss ctrl+alt+del to restart, and now it keeps going round in that loop.
I turned off the power to put the other memory sticks in , which I did and now it won't boot at all.I even took them out and tried to reboot but I now don't even have a signal to the monitor as the light is staying yellow and not turning green.What's happened????Is it time to panic yet?
Unplug all usb devices and check no disks in drives and retry.
There are no usb devices attached and nothing in the drives.Still no green light or POST.ooooops!
no single beep either!
I took out the cmos battery and replaced it again to see if this would reset the problem, but that did not work.HELP!!!!
