After loading a driver for an external usb wifi adapter, this laptop is having issues booting.

Symptoms are:

Boots up but loops after 15 seconds or so, don't know if it is actually posting
Black screen (as in screen does not turn on at all)

Things tried:

Pulled all memory, all peripherals and reset CMOS battery. Then inserted 1 memory stick with no changes.
Pulled battery, no changes.

Any ideas of what to try next?

This question came from our site for system and network administrators.

Dose an external monitor work? – t1nt1n Jan 22 '12 at 18:48
Just tried one, no it doesn't. – Jared Eitnier Jan 22 '12 at 18:57
Tap F8 at boot, you will get a boot menu to try Safe Mode and various Recovery options. Try those, Report back. – Ƭᴇcʜιᴇ007 Jan 22 '12 at 19:11
How would I do that when as mentioned above that my screen is black? – Jared Eitnier Jan 22 '12 at 20:36
Use a bright flashlight on the screen, do you see anything while booting?, if you do see the post screen using the flashlight your backlight or inverter has failed (LCD screen only). – Moab Jan 22 '12 at 20:54

First, this is not a driver problem as bootup doesn't involve drivers. If the machine does not POST, pull the hard drive and see if it POSTs. If it doesn't its time to call HP. If it does boot into cmos reset to defaults, and try again.
