Hi.
Over the past week, the screen on my HP Pavilion ZE4323 has started to go very dark shortly after start up. Windows XP is still running as normal - I can make it out if I shine a torch on the screen.
I've solved the problem to a certain extent by using the 3 restore discs to restore the factory settings. The result is that the screen shows the installation process and then runs through the introductory video ok. If I leave it with the desk top showing, there's no problem. No darkening of the screen at all.
However, if I go to the next step and try and install SP2, the screen darkens about 5 minutes into the installation process. A similar thing happens if I try to read something off an external hard drive.
At first I thought it could be overheating. So, I completely dissembled the laptop, took the fan and heat sink off, used an air can and generally cleaned it up. This doesn't seem to have made differnce though.
I then thought it might be the backlight or the cable connector. Don't think so, because as I said above, it's fine when use the restore disks. In fact, provide I don't do anything other than move the pointer around the desktop, all appears to be well.
Any ideas, please? Corrupt Windows or registry, or perhaps a virus?
Regards
