Question about Foxconn NF4UK8AA-8EKRS Motherboard
The computer will have to be restarted after most OS updates, etc. and has worked normally until recently. Now when windows shuts down, some 10 or 15 seconds later the computer begins to start. I shut off the logo to view the screen. The initial black screen with Phoenix BIOS appears with the task bar at the bottom "Del to enter set-up", etc. However the screen is frozen, no memory check etc. Esc, Del, F10, three key boot, nothing will move into POST. It is necessary to shut off power, turn back on again, then press the start button on the computer. POST checks the memory and starts the OS too fast to read the progress. The mother board functioned flawlessly for 18 months. It freezes on hot re-start only. Any help available. Note, all BIOS settings are original except I turned off the WinFast logo to see the screen on start up.
The system in the bios must be set to halt on all errors. Go into the bios (F2 or Del) on start up and in the standard bios settings, there should be 'halt on all errors enabled. Set this at off or dissabled. Next time you boot the pc it will not stop if there is an error and should show you the problem cause in the boot up sequence. If all else fails follow the previous solution post to clear cmos, to do this locate the 'JBAT1' terminal and put jumper cap from pins 1-2 to pins 2-3 for a few seconds, then back to 1-2. Start pc reset time and date and if unsure highlight default settings menu enter, save settings then exit and hopefully it will boot into windows.

Simple. clear the CMOS by using clear cmos jumper setting or remove the cmos battery and put it again and then change the bios settings as per ur machine configuration.

Tips for a great answer:
Whenever a recoverable error occurs during POST, the BIOS displays an error message
describing the problem (see Table 53). The BIOS also issues a beep code (one long
tone followed by two short tones) during POST if the video configuration fails (a faulty
video card or no card installed) or if an external ROM module does not properly
checksum to zero.
An external ROM module (for example, a video BIOS) can also issue audible errors,
usually consisting of one long tone followed by a series of short tones. For more
information on the beep codes issued, check the documentation for that external
There are several POST routines that issue a POST terminal error and shut down the
system if they fail. Before shutting down the system, the terminal-error handler issues
a beep code signifying the test point error, writes the error to I/O port 80h, attempts
to initialize the video and writes the error in the upper left corner of the screen (using
both monochrome and color adapters).
If POST completes normally, the BIOS issues one short beep before passing control to
the operating system.
