Problem started with usb mouse not working, then keyboard stopped responding. Finally installed a new USB CARD and all was OK. Few days later I noticed the sound was not working. After CHECKING all connections I REBOOTED in hopes that would help.

At the point of rebooting, the monitor did not come up. I've checked all connections, tried a different monitor, nothing works. When I press the power button, it sounds like everything is going into the normal power up routine, but the monitor stays blank.

My choices.... Find the answer to this problem and get things up and running. Second choice ... assuming the disk is OK how to put it into another pc and boot from it. This disk is SATA, the other computer that I would put it in is the older style, ide CABLE, so I guess there is some type of cable that would bridge the difference.I would first try another monitor or try the current monitor on another computer.What OS ? ?
If it is newer than WinME it's probably not going to boot properly in another machine...
What do you want to accomplish here ? ?The monitor works on other computers, but other monitors will not work on this system. My goal in being able to use this hard drive is not to spend days/weeks trying to get PROGRAMS and data on another system.Well it sounds like you have had multiple hardware issues...but if you suspect the HDD is going South DLoad and run the FREE diagnostics from the drive maker's site...
Follow the instructions for creating a bootable floppy/CD and run the long test...
