Check the Cables if they are loose.

Try booting without the GFX card.

Does your system have Onboard Graphics?

then connect the VGA/DVI plug to the Onboard port.

Also check for Faulty RAM modules since you mentioned garbled lines coming on your monitor.

Mostly it sounds like a RAM or GFX card Issue.

Have you checked the system with a different monitor?

Does the computer have an internal speaker. If not buy one and connect it.
It may help with diagnosing the problem as the post should produce a beeping noise.

As to the garbled lines, this could mean anything. Faulty ram, gfx, cpu error, loose cables, bad vram.
