Sounds like a hardware problem to me.

Hi<br />
<br />
I have a Macbook Pro (MC374LL/A) which won't boot anymore<br />
<br />
I followed the recommended steps in the following link <a href="http://support.apple.com/kb/ts2570" rel="ugc">here</a> but wasn't able to obtain any imrovement<br />
<br />
1) Safe boot doesn't work<br />
<br />
2) Reset the NVRAM / PRAM doesn't work<br />
<br />
3) Start up your Mac while holding the C key doesn't work<br />
<br />
&nbsp; The DVD I manage to enter is immediately ejected<br />
<br />
On each boot the grey screen lasts barely two seconds before the MBP switches itself off<br />
<br />
Any ideas ?<br />
<br />
thanks<br />

All of Apple's hardware is produced solely by Apple Inc., who determines internal systems, designs, and prices. Apple buys certain components wholesale from third-party manufacturers. The current Mac product family uses Intel x86-64 processors. All Mac models ship with at least 1 GB RAM as standard. Current Mac computers use ATI Radeon or nVidia GeForce graphics cards and include a dual-function DVD and CD burner, called the SuperDrive. Current Apple hardware includes the iPad, iPhone, iMac, Mac Pro, Macbook, iPod and Apple TV. Discontinued hardware includes the Apple I, Apple II, and the Apple III, the Lisa, the Newton, the Quadra, Performa, Centris, Macintosh II and LC series, the Power Macintosh, iBooks and the MacBook.

A laptop or notebook is a portable personal computer with a clamshell form factor, suitable for mobile use. Although originally there was a distinction between laptops and notebooks, the former being bigger and heavier than the latter, there is often no longer any difference. Laptops are commonly used in a variety of settings, such as at work, in education, and for personal multimedia. A laptop combines the components, inputs, outputs and capabilities of a desktop computer, including the display screen, speakers, a keyboard, and pointing devices (such as a touchpad or trackpad) into a single unit. The device can be powered either from a rechargeable battery or by mains electricity from an AC adapter.
