Hi there,
i recently bought a second hand HP Compaq tower from a computer fair. it was working fine for the 1st three months. in the 5th month however, was when all the problems started. my computer started switching off while i am on it. then when i go to turn it on again, it would not power up, but instead show me a red flashing light. it flashes for 4, each one second apart. i have been given to solutions: replace motherboard, or power supply??? can someone please tell me which of the two it is as i am quite tight with money at the moment and would really like to spend as less as possible to fix my problem. thanks very much and any help given is very much appriciated. :)
It could be overheating. Make sure all the components and fans inside the tower a clean of dust. Get a can of compressed air and blow all the dust out. You could also try removing and re-seating all your pc cards, memory sticks and cables.
