I'm working on a Compaq Presario S3100NX. When you boot, you'll get the Compaq splash screen and you can get into BIOS no problem but hitting F10 for system recovery results in black screen. If you let into continue booting you get the "We apologize for the inconvenience window". If you select to boot normally, it goes to a black screen and hangs. If you select safe mode, it starts loading drivers but hangs on "\DRIVERS\AGP440S" every time.
Tried loading Knoppix and you'll get one penguin in the upper left window and it hangs.
Loading the Windows installation CD, it starts loading but shortly just stalls.
Tried loading a boot floppy but just gives an error.
Reset the BIOS to defaults, no difference.
Removed all the hardware and no difference.
Removed the CMOS battery, left it overnight and no difference.
