i have a hp laptop and it will not boot up. it is an xp machine and the lights come on and nothing else happens. please advise. thank you

In order to solve the problem, you are advised to write more about your system specification. And also when this thing happen and what exactly the problem. Is the computer fan spinning during boot? So it is just the monitor issue? Or only the lights are on?

I had the same problem. My computer would not boot just a black screen and the cpu, fan and lights will just work. I even reseat the RAM. I eventually remove a few items hoping it is just not having enough power. I found out the RAM was the problem. Right now everything is working. I don't know if the ram socket got fried or something but I plan to buy new ram and test it out.
