Hi this is my first post and im a novice with computers so please bear with me.
i have a compaq presario about 3 1/2 years old. has worked perfectly till the other morning. switched on got lights, fans started but made different noise as though no load on them, nothing on screen. friend suggested graphic card fault. as need for kids A level work went to PC Wo*$?d tech guys they tried new card still same. after reading some posts on your site also tried removing and replacing Ram still nothing but dont have spare to try. is this a likely prob. Today took out hard drive and recovered all data so this is ok. no visible signs of burn out on any hardwear any suggestions? please.
