I hope this is a proper Forum to post this.

I've had leopard installed on my HP9250f for awhile.

it had been working great so far except for intermittent 'blue screen' I get when booting up the computer. However, it has been getting worse recently. now 5 times ouf of 5, i can't even see my MAC desktop at all.

Not sure if it's related or coincidental but I noticed it getting worse after i recently installed MacDrive on my Windows 7 HD (a separate HD from Mac OS X). since the installation of MacDrive, every time i load into Windows 7, the computer would do hard drives check for errors. Wondering if this somehow corrupts or changes my Mac OS X boot up affecting my Display kext????

I would greatly appreciate it if anyone can help me fix the issue WITHOUT having to re-installing my Mac OS X.

Thank you.

update.......finally able to get back to desktop last night......by pressing SHIFT while booting up. Not sure if it was coincidental or that was the trick. Had to reconfigure background settings......good to go again. HOWEVER, this morning after activating from screensaver, the blue screen came back but this time, it was more like a 'transparent' blue screen. i can still see the desktop but 'faintly'........I am really lost!!!!
