Receiving a "No Signal" message on monitor

when i tried to switch my pc on today it took 4 attempts as it kept coming up no signal, i had this prob with the new stick but not the old one till today, any ideas gent please.

if it coming no signal, that is usual the screen dee check all cables to the screen are fully in

will do m8, i was getting that when i tried the other stick could that be the problem with that aswell.

when its says no signal thats means the screen is getting no signal from the tower

maybe il try that other stick. disconect every thing .

before you do anything make sure you have the computer working it could be the g.card needs reseating find the problem first

im using m8, iv only got the 1.

did you find a lose connection

just gave everything a wiggle and it came back on, thats why i asked m8.

once you know which conn is lose tight it and then try your new ram
