computer says Windows has encountered a problem communicating with a device connected to your comput

[jim_ree]

I don't know much about computers at all I just recently purchased this one from Craigslist it works just fine was perfect let's Monday came home my husband says he put in a USB zip drive or something into the USB port on the sideand who knows what happened after that but by the time I get home after him and I had a fight my computer no longer works and all it says is window has encountered a problem communicating with a device connected to your computer this error can be caused by unplugging a removable storage device such as an external USB drive while the device is in use or by faulty hardware such as a hard drive or CD-ROM drive that is failing make sure any removable storage is properly connected and then restart your computer I restarted it and it does the exact same thing so I pressed f11 numerous times and it will not let me go to the system recovery is just a black blank screen I press escape and got to do one of the other tests and it says it felt it gave me an error code of Bi-Lo hd8 and it says a smart test failed on the drive and then I got another error that says   b i o h d - 5like I said I have no clue about computers or how to maneuver around in them I know that it was working and now it's doing absolutely nothing I just paid for it and really really really really need it to be working and would appreciate anybody that can help me! Like I said I know absolutely nothing about computers or their parts so please if you have any suggestions for me make sure you break it down as far down as you can LOL thank you

Hi

So it's one of these....  HP Pavilion All-in-One MS227 Desktop PC  

AND craigslist is some American (US of A) Classified Ads site?  So you have no comebacks backups or any thing?

First:- Turn off the computer, press and hold the PWR button for 4 seconds.

Then - Leave only keyboard and mouse connected, disconnect all externally connected
devices such as Docking Station, USB storage devices, displays, and printers.
Unplug the AC adapter from the computer.

Next - Press and Hold the Power button for 15 seconds to Hard Reset.
Rinse and Repeat

AND/OR - Power on your PC, press Esc (repeatedly), then F2 at the prompt.
Choose System Tests (Fast Test does a 4 minute hardware check).

Try the above as best you can and post any results please.
