Looking for a refurbished Samsung NP520U4C motherboard BA68-08181A10. Hard to find. Is there another motherboard that would fit since I can't seem to find one. Thanks for any help! Bob M. :D

Welcome to Motherboards.org.
Specs link on that Samsung unit.. http://www.samsung.com/us/computer/pcs/ ... 01UB-specs
What is wrong with the one you have now? Physical damage or other problem?
Not many sources for replacement, except from the manufacturer or perhaps a good used one on eBay.

The one I have now was determined to be faulty by the Geek Squad. It had Windows 8 and when turned on, it would get caught up in a repair loop. I had taken the drive out and attempted to use the chkdsk utility to repair it but to no avail. Now, I am looking to replace the motherboard at a reasonable price. Thank you for your response. Bob M. :D

.. caught up in a repair loop..

I would want a second opinion about a bad motherboard, after seeing that bit of news! May only be a corrupt software problem, and a repair operation in the proper manner may cure its ills. Or a hard drive that is failing.
There are many links found if you search for that problem. But put more trust in Microsoft® and Ton's Hardware® links.
What may work for one person may not work for all.
If you can get into the BIOS with no problems, then think more toward a software problem. Can you boot directly to an OS install disk, preferably the same as is installed on the system?
The problem may have been caused by a virus or Trojan, and is now in a critical state. Ensure your antivirus and firewall programs are potent and up to date.

Thanks for your help. Now I have to put it all back together. I'll give it a shot!

No offense to the 'Geek Squad', but sometimes a simple cause may appear to be more serious.
Bench time for diagnostics has a limit, and can affect turn-around time and profits for a company.
Not all, but some techs may default to a "get a new one" thought, when a bit more time would disclose a less costly outcome.
We all hear stories of "grease monkeys" telling people an alternator is bad, when all you need is a belt. Or an automatic transmission is bad, when all it needs is a new filter and oil change.
Hope your problem has a simple fix.

Well, put it all back together & it turned on. Much to my chagrin, it returned to the Windows 8 repair loop. Cannot break out of this with F2 (BIOS), F4 repair, nothing seems to work. I did download the Windows 8 recovery file, and loaded it onto a USB Flash drive. Cannot get into BIOS to change to the USB. Any other thoughts??? Bob M.

Engaging the BIOS setup has to be done before the handover or bootstrap cycle. Repeatedly pressing the key or keys to enter the BIOS as soon as the stats are on view is the 'window' to BIOS access. Some systems can do the POST process in 10 seconds or less. And many systems do not display the POST process, only a logo!
Common BIOS entry keys are the [del], [F2] or [F10].
You might be able to start in 'safe' mode by pressing the F8 key just as Windows begins its loading.

disconect the HDD to avoid entering in windows repairing cycle

you can clear the BIOS CMOS also so that the first time to boot u will get forcedly the option of entering BIOS setup
