Overheating is a possibility. However, once the computer is cold again, it should start soon. As Mike suggested, you should blow dry air throughout the intake and out vents. Even better would be to remove the back cover an thoroughly remove any dust built up in the board and especially the fans and heat sink vents. The cleaner, the better. If this doesn’t solve your issue, try using a different hard drive or even loading with a OS from a USB. I recommend downloading H/W Monitor to check your CPU, Hard drive and graphics card temperatures. On idle, they should be around 30-40 Celsius. Under high loads it can reach up to 80-100 Celsius, depending on the laptop’s ability to dissipate heat. Normal use, should be around 50-70 Celsius. Make sure that the fans are spinning well. Last but not least: the heat sink may need to be disassembled, cleaned and added new thermal paste in order to transfer as much heat as possible away from the CPU/GPU.

Have you blown out any dust? Could be overheating.

Hi,
What is the model number of the laptop?
Does it do this with the charger connected and switched on?
Have you checked in Event Viewer to see if there are any Critical, Error or Warning events that may show what is going on?
