I have a very strange situation that I have been asked to look at by a friend:
It is and eMachines E4252 AMD 54 x 2 Processo 4000+, nvidia Geforce 6100 onboard Graphics, 1 GB DDR2 Ram (2 x 512), 150GB Sata HDD with Windows Vista Home Premium Installed.
Basically, as I understand it, the computer started shutting down as it leaves the "safe/with networking/last known good configuration" screen, all power stops all fans stop. Sometimes, after repeated attempts, it would start up and work normally.
I took it home and first changed PSU, same issue; I then removed/swapped RAM for some new ones I have here....same result. I tried CMOS battery and removing IDE/power to cd drive
It will sit at thesafe mode screen for hours with no problems and also in the bios with no problems, but as soon as it progresses past the safe mode choice screen it shuts down and on the odd occassion it does "go all the way" it will shut down at any point in time.
I have checked the CPU temp and it is running at about 35c so not overheating.
My only thoughts left are mobo??? Anyone here have any further suggestions as I am going bald scratching my head.
Thanks in advance
