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.

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.
