Getting black screen after booting screen after...

hi im wesley iv had the same problem before with my compute. the problem might be i broken ide cable or a loose connection make sure the all cables in your pc is connected properly and if so change a few of the cables if it doesnt work you might have to get a new hard drive and also check if your cpu is in properly and not moving around at all then go into your bios and check the temprature pf the cpu and try running a health test from the bios it might be you fan isnt making proper connection with the cpu causing it to over heat and automaticall switching off for safety.
