HA that happened to me with this one i have now , i replaced the ram and i tried everything , seating ,cpu all the stuff i could , i was ready to post on here when i thought reset cmos? and it worked
anyway back to topic lol , erm yeah also is there an additional power connector on the mobo usually 4 pins seperatee from the normal 20 or 24 pin connector , i think only p4 systems have it so it may not , if it does tho is that connected cos that gives juice to the cpu
is the cmos set to the reset position as the shop may have done this and left it like this by mistake .
is there an led on the mobo and if so does it light , some moherboards have different led colours for faults etc , kinda like a beep code for death people
