my computer crashed one day and i tried to boot up the computer with a bootcd and repartition the hard drive and reformat the drive but when it is reformatting, the screen shuts off and it stops and sometimes it has errors where numbers and letters start popping up. i went and got another hard drive to see if that was the problem but it was not it. would anyone know any possible solutions? i was going to try to replace either the motherboard or the processor or maybe even the ram.
