cause of RSOD

[woo124]

No, in my case, it's either ROSD after the blue screen or the Platstation2 logo.
It doesn't go to the browser screen at all.
One thing I 've noticed, though, is that when it loads OK, the initial blue screen disapprears quicker.
For ROSD, the blue screen lingers longer, and it zooms in much slower before getting to the next screen, which is RSOD.
Also, I had my laser cleaned right after getting the MI installed.

Thanks
