Re: PC Won't Boot

Do you still have your old ram? If you do, try putting that back in and see if it will boot.

try to see if it's posting mate...remove ram and boot it up if it beeps, replace with good ram, if not...try removing vga card and see if it beeps....sounds like ram worth a go

check psu selector switch is in 240v position not moved to 115v also if you have removed bits re-check you have fitted correctly, ie pins on proc ok memory fitted some of those boards you have to really push to get the sticks in the socket

also have a look here

Hey thanks hatab is the psu selector on the power pack ? i cant find it , there's a solid green light on the motherboard when the pc is on and shutdown ? thanks for the attachment i'll have a look at it after and see how i get on much appriciated thanks! :xmas:

psu voltage selector on the outside by the mains input, if it has been pushed to 115v then remove plug before moving to 240v.

Re: PC Won't Boot

my advice is to undo what you did and see what happens. might need to clear your cmos.

Re: PC Won't Boot

So has this been resolved now? I put the two threads together to hopefully help. Was this the ram in the wrong slots? Or a loose graphics or other?

Re: PC Won't Boot

How many ram slots do you have, how many sticks of ram are you using and what type?
