Trying to help a pal whose PC will not boot.
Problem started by sometimes not booting completly past 'Checking NVRAM' Switching off, waiting and trying again sometime worked. When boot was successful and left switched on PC worked OK!
Now it will not boot at all. Monitor will not show any sequence when connected to the PC, but when disconnected from the PC shows 'No Input or Disconnected'
Have tested it on a known good Monitor, same result.
As it has an integrated video chip, unable to eliminate that.
Tested PSU at various points and got 5.12 Volts
Fans are running and Floppy Drive sounds like it is seeking.
Unable, so far, to replace BIOS battery. Is it possible to produce the above problem if below spec?
His PC is a reasonably old Dell Dimension. P3, 1Ghz with 256 RAM. (Have swapped RAM)
Any help would be appreciated
