step 1: Try to download a linux version like "mint" or "ubuntu". Prefferably the mint dvd iso ( the operation is like windows with different name of shorcuts etc). They are both free.

step 3: Go into BIOS and make the usb first boot device.
step 4: Then boot from usb.
1) If you have errors in ram stick it will not load.
2) If your hdd is faulty when the linux is loaded check the disk
3) check other components
4) live cd or live usb will not install anything unless you choose this option
