Hardware

I was trying to install Windows SBS 2008 (64-bit) for testing purposes, but I kept receiving this error "VT-x is not available. (VERR_VMX_NO_VMX)" from Virtual Box everytime I tried to Start the system.

I enabled Hardware VT from the BIOS (under Security menu) and restarted the computer - still the same error.

I disabled Execute Bit from the BIOS - still the same error.

SCENARIO: A Vista server (Home Edition 32-bit), 3 XP clients and other 5 Vista clients joined together on a Workgroup. Twice a day, we have to restart the Vista server as the XP machine lost connection when trying to access a file from the Vista server and XP clients give the following errors:

• when opening My Network Places = Error: Workgroup is not accessible. You might not have permission to use this network resource. Network name is no longer available.
  
• when opening shared/mapped folder = Error: %Share% is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions. Access Denied.

When designing a webpage, my computer used to freeze. When I checked the Task Manager, the CPU Usage reached to 100% wherein 98% is used by iexplorer.exe. I have been testing one of the webpage in Internet Explorer 6, 7 & 8 and each one of them made the CPU Usage reached to 100%. Using Firefox alone had no effect - meaning, it had its normal CPU Usage while testing the webpage.

I checked my CSS and tried to delete some of the codes until I finally saw this code which uses all of my CPU resources:

#content { height: expression(document.getElementById("content").offsetHeight); }

That is the code for IE6 to compensate its inability to interpret top:0; and bottom:0;

First step to try:

- boot computer from Windows CD and choose repair (R)
- from command prompt run: chkdsk /r
- when checkdisk finishes, remove Windows CD and boot WindowsXP normally.

Second step to try:

- Follow procedures from Microsoft on how to recover from a corrupted registry that prevents Windows from starting  http://support.microsoft.com/default.aspx?scid=kb;en-us;Q307545

Third Step to Try:

- made sure ACPI, Plug & Play, USB all enabled in BIOS
- moved mouse from the ps/2 port to the first USB port
- booted using Safe Mode
- waited until it hung at Mup.sys
- removed the mouse cable from the USB port
- (3 seconds or so pass, the screen went black and safe mode appeared)
- restart the system
- boot normally into XP
