In the right hand pane, double click BootExecute.

The default value of the key is autocheck autochk *

* means every drive is checked for consistency. Just add /K:C at the end before *. /K switch will disable autocheck on C: drive at Windows startup. So the final value should look like this:

autocheck autochk /k:C *

If you want to add more drives, the key should look like this: (disabling C and D drives)

autocheck autochk /k:C /k:D *

autocheck autochk *

Manual checking we can check manually chkdsk command using command prompt

    open command prompt (start=>run=>type "cmd" and hit enter

Beep sound and their problem

Beep Sound?

   Usually hearing any beep sound, the problem is occur on your RAM, but we have another possibility.

  1. First you need to clean your ram and ram slot after that reinsert the ram, Not working follow the steps

Audible beep codesThese beep codes are heard through the onboard piezoelectric speaker or, for boards without the onboard speaker, through a speaker attached to the board’s line out audio jack.

Beep code Sequence/pattern Meaning Troubleshooting steps Single beep One 0.5 second beep F2 Setup / F10 Boot Menu prompt This short beep occurs when the BIOS is ready to accept keyboard input. No action is needed. Single beep continual long beep Auxiliary power may not be connected to an external graphics card Check the documentation for any external graphics card installed for information on connecting an auxiliary power source. Repeating single beep One 1.0 second beep, then off for 0.5 seconds. Repeats until computer is shut down. BIOS recovery failure Try the BIOS recovery again. Do not interrupt the recovery process by pressing keys or disturbing the AC power connection. 2 beeps On-off (1.0 second each) two times, then 2.5-second pause (off). Entire pattern repeats once. Then the computer continues to boot. Video error (no add-in graphics card installed) Reseat add-in graphics card. Make sure a compatible processor is installed. Related Topics: No video and two beeps during boot Intel® Processors and Boards Compatibility Tool 3 beeps On-off (1.0 second each) three times, then 2.5-second pause (off). Entire pattern repeats until the computer is powered off. Memory error Reseat the memory. Make sure that the contacts on the memory and the socket are clean. Try removing one bank of memory modules at a time. (Some systems can require a memory module in Bank 0.) Try using memory modules from the same manufacturer with the same part number and speed. Check for a faulty memory module by trying the memory in a known good system. 3 beeps Three 0.5 second beeps. Then the computer continues to boot. BIOS recovery succeeded No action is needed. High/low beeps Alternate high and low beeps (1.0 second each) for eight beeps. Then the computer shuts down. CPU thermal trip warning Check that the processor heatsink/fan is properly installed. Check that the thermal interface material is sufficient and is spread evenly. Rising and falling tones Rising tones: 0.5 seconds on followed by 0.25 seconds off, then repeats with next tone. After highest tone has played, repeats sequence with falling tones. BIOS recovery progress update This beep pattern is normal behavior. No action is needed.
