I have an hp g56-122us laptop. The problems started a month ago after I took apart my laptop to see if I could put a new sound card in there. I handled the parts pretty roughly, especially the motherboard. After that, every time I turned on my laptop, the power was on, but the screen was completely black. I always had to wait 10 minutes to force the laptop off, then turn it on again. Then, it would boot normally, but the screen flickered and sometimes, the laptop would shut down when I did CPU intensive tasks. I did a chkdsk /r and a Windows Memory Diagnostic, but both showed that my hardware had no problems. I saw a BSoD that said "Physical Memory Dump ...%" shortly after. Now, the laptop  powers on, but the screen stays completely black. My old trick doesn't work anymore. Only the light on my Caps Lock key repeatedly blinks white. The lights  on the touch pad and the WLAN key are off which shows that the drivers can't load. I've tried inserting a bootable cd into the optical drive, but it can't boot from there either. I've dismantled the laptop again to make sure I put everything back EXACTLY the way it stated in the manual, but no luck.

You can try the NO POST procedure by using a different memory stick, then disconnect all peripherals down to bare minimum (CPU, Power, Video, RAM) if it doesn't work try another CPU, if still no luck then it is a Motherboard issue.

I like the suggestion given by Eat_Babies. I think you should give it a try, it should definitely work. Otherwise you can contact a professional

Make sure you use proper ESD procedures so that if you haven't already shorted out your computer, that you won't add to the problem you are having.
