Product: HP G62-a10EP

Windows 7 - 64bit

Display drivers:

-Intel HD 5000

-Ati Mobility Radeon 5470

4 gb RAM

Processor: Intel Pentium 2.00ghz


Step by step, what happened:


I was playing a game called Torchlight II yeasterday and suddently it froze. Then, it went into a black screen. I thought that it was a overheating situation as this pc overheats a lot, so after 10 minutes with no response (and still hearing sounds from the game), i did a hard reset. To my surprise, after the initial Windows is Starting screen, the monitor just went black with no video display. So here's what I did to try to solve this:


Went into safe mode and disabled the Ati driver. Then I could enter the pc normally but with a VGA display, no Intel graphics. So I did a clean reinstall of both graphic drivers from hp support and the problem still ocurred. If I disable either one of the display adapters, the computer starts  in vga display, no intel, no Ati. If I enable them both It goes into the black screen after Windows startup. I searched all over forums and I did a disc check and a anti-virus check. Most forums say that in order to solve this I have to enter in the advanced options in the BIOS and toggle some options there, but my version of BIOS doesn't allow it and it's the latest update. So I'm really running out of options.


To clarify: If I disable either the Intel or the Ati, the computer starts with a vga display. If I unninstall one of them it tries to install it after I start the pc and as soon as it suceeds it enables it and: BOOM, black screen. I tried updating to latest version both drivers and the same problem occurs.

Any help would be greatly appreciated.
