Well today I finally decided to look at my laptop which died on me a few months ago. It is a HP DV6305 and I had this issue where the laptop would boot up with nothing on the screen , all the lights turned on and the fan. I had it looked at by a computer repair shop and they said my motherboard was dead so I left it in a closet up until today. I browsed the internet and found a strange solution but tried it anyway. It involved heating up the video card area as my laptop series has an issue where the vga cooler doesn't make contact with the video card. 5 minutes later pc booted 400.00 repair for 0.00
