Computer will turn on, screen won't.

If you regularly use your computer for prolonged periods of time then this will cause the computer to heat up rapidly. It sounds strange but over time the graphics card (typically an intel chipset) can actually melt away from the motherboard. This will eventually cause the graphics card to come away from the motherboard and the connection will be terminated. To fix this use a hairdryer or another heat emitting device and hold it over the graphics card for around 2-3 minutes. If necessary do this for longer but be warned that doing this too long can permanently damage the internals of your laptop. Try to point the hairdryer near the connection between the motherboard and the graphics card.

Hope this helped!

You should try to boot the computer with a boot disk or usb that has anti-virus software built in. This will start the windows machine and will scan the hard drive for trojans. It will find & remove trojans which may solve the problem. Read More - http://www.howtogeek.com/175234/how-to-u...

Else, you can format the hard drive (only if data is unwanted) to erase the infected drive content. Reinstall the OS and use machine as usual. But if you can't afford to loose data then try to boot the system with DVD mounted with anti-virus. If possible also try to run hardware test to diagnose any H/W issues.

it is probably your ram or cpu or gpu, in that case you will need to replace your moutherboard or see an expert about that.

Change the ram module,commen fault,4gb ddr,fault

hello. I have similar issue with my laptop. after the windows installation it works smoothly and when I install graphics driver my laptop wont start. it will only show windows animated logo on the black screen and screen will run black. I have tried 3 different drivers and I got a chance to start it on one of them but it runs 3 to 5 seconds and screen freezes. do I have to change the mother board? or is it something else
