Windows Memory Diagnostic Tool

Starting with Vista there is a tool for memory (works on 7 too).

Windows Memory Diagnostic Tool (PC)

Windows Vista and Windows 7 include a Memory (RAM) Diagnostic Tool that performs a scan of your computer’s physical memory and may help identify any possible errors.

Using this tool will require a reboot so please save any documents you have open.

- Click Start.
- In the Start Search field type in Memory and hit Enter.
- The first option you see should say Memory Diagnostic Tool.
- Run the Memory Diagnostic Tool – A window will pop up asking you if you want to reboot and check for problems now or check for problems the next time you restart.
- If you choose to restart now, your OS will reboot into the memory diagnostic utility.

Win95 – Restore Registry

To restore your registry files, follow these steps:

  • Restart your computer.
  • Press the F8 key when you see the “Starting Windows 95″ message, and then choose Safe Mode Command Prompt Only from the Startup menu.

Type the following lines at the command prompt, pressing ENTER after each line:
cd windows
attrib -r -h -s system.dat
attrib -r -h -s system.da0
attrib -r -h -s user.dat
attrib -r -h -s user.da0
ren system.dat system.daa
ren system.da0 system.da1
ren user.dat user.daa
ren user.da0 user.da1
copy system.bu system.dat
copy user.bu user.dat

NOTE: This procedure assumes you do not have any files named System.daa, System.da1, User.daa, or User.da1. If you do have files by this name, select a file name extension that is not currently in use.

Restart your computer.
