I'm struggling to work this out - (Windows 7 32-bit on a HP pavilion dv2500) I rebooted about a month ago (a few days after upgrading from vista to 7, but maybe this is unrelated?), and there was just a black screen, no cursor blink, no bios, nothing, but the disc light is flashing, then Windows startup sound goes off, so it has booted after all. I tried attaching an old VGA monitor and sure enough there's my desktop. I close the lid in frustration and unplug the external monitor. When I open the lid again the display comes on this time but its in 1024x768 (not 1280x800), and when I try to readjust the resolution its just not available as an option - loads of other resolutions, but not 1280x800.
So, I install the latest nvidia driver, flash the bios with the latest version, restart, but still the same. Randomly once when I F10 into the boot menu (which is appearing on the external VGA), then do a save and restart from there, the laptop display came on again, boots into Windows fine, at the correct resolution. I use this for a month or so, it sleeps and resumes no problem (I didn't restart it), everything working as it should.
Then the latest windows update comes along and requires a reboot, and I'm back at the same point - if I don't connect the VGA external then I've got a blank screen (no backlight, nothing), even though windows has started. But if I connect the VGA, put it into sleep, disconnect the VGA, resume from sleep then I've at least got the laptop display, but at the wrong resolution.
Any ideas, is the graphics card shot?
Sorry for the long-winded explanation.
