I need help!! I removed my ram card to check the model and put it back in but it will categorically not tighten so the ram card is loose, i read online however that this shouldnt be an issue, so i tried turning on the pc, and the usual blue light is flashing orange and beeping 3 times continuously, i have tried both ram slots and got the same result, it is an HP Pavilion so a little dated but runs perfect for what i need, anyway help would be hugely appreciated i need to get my uni work done!!
