Hi all:
I have an HP ProBook 4520s with Windows 7 Professional. 2 days ago it crashed. After a few restores it worked again for a little while. But then when it maxed system resources, it crashed again. Now when I turn it on, the built in monitor is black and the external monitor shows a striped pattern. Every second strip is readable and the others are not (looks the same as having the wrong refresh frequency set).
I suppose it's the graphics card and/or motherboard. Any way I can test that? Could it be something else? I recently upgraded RAM but I tried it with each of the modules individually with no luck.
Can I find any info in the minidump files?
Any suggestions are appreciated.
Thanks,
Gunter
