XP Works Fine, Mac OS X Randomaly Black Screen

[Dipsi D]

Hey there,

Macbook spes:

White Macbook 2.2GHZ C2D Early 2008, 1.5Ghz, 120GB.

Here's my Macbook story:

The laptop had Leopard OS X 10.5.7 installed on it, when it started with randomly sleep/black screen - which sometimes I could wake the screen back by pressing the keyboard, but screen goes back only for a second than goes back to black - seems like MBK took a nap/went to sleep mode, but with no option to get it up for more than 1 second. When "hitting keyboard" in order to get it back stopped working, I moved to keying F1 & F2 which also helped to get screen back for no more than 1 second - than it also stopped working, and no other "solution" was found. Than I tried resetting ram, resetting power, nothing helped, so I inserted XP install and erased the HD - made a fresh XP install with no bootcamp (tried to install OS X from flash drive OS X DVD backup I made, mbk booted from flash drive, but after apple logo than 1 sec blue screen and than black screen again with nothing helped to get it back). xp installed successfully- of course several drivers were missing - mouse track pad was working and also button, but after I restarted the system than mouse button stopped working, and than got back randomly, but no screen problems - no sudden black screen.

After that - I tried to make a fresh install of Leopard 10.5.6 again, I Had it on a flash drive which I made as a backup - so I formatted the entire HD with windows xp DVD (deleted windows xp), than again tried booting from flash drive in order to install OS X in the blank internal mbk hd , but after apple logo than 1 sec blue screen - mbk screen got blank with nothing helped to get it back - than tried to play in mbk user single mode - than loaded flash again - suddenly OS X installation loaded - went diskutil made 2 partition - and baaaaam than again screen went off - got black.

Apple Hardware Test showed no problems.

Anyone has an idea what could cause this issue - I thought maybe Hardware issue, but than again how could xp load well with no issues except mouse button randomly function?

 

Any respond will be appreciated, sorry if I have some English grammar/spelling mistake s- wrote a lot and "fast" so hope mistakes are few to notice .
