I have just recently upgraded every single part about 3 months ago this includes Cpu, Gpu, Motherboard and ram, But this issue only recently started happening about a week ago.My pc would sometimes just shut down and automatically start restarting other times the displays will just turn off and do not turn back on so I have to manually restart the PC other times the computer will freeze entirely and start buzzing, I have to restart it to get it back. I have not been able to find answers on how to fix this issue as it seems to be three different i

Random shut down and restart??

Computer: Intel (R) Pentium (R) Dual cpu
E220@2.406hz
2.42 GHZ, 2.00 GB of RAM
Windows xp

Ever since I replaced the fan (with heat sink) the computer has randomly shut down and then restarted, at first during streaming, and now, will shut down and restart anytime. I tried to replace the graphics card to no avail. *Confused *Mad

One suggestion was to replace the RAM.

Any suggestions on how to repair my computer?

Windows restarting automatically after shut down

Hello,

One of the possible reasons why your PC is restarting automatically after shut down
are due to broken components on the boot configuration data of your system.
To isolate the issue, we suggest that you perform the following steps to trigger
SafeMode through the Windows Recovery Environment (WinRE) option. To do this, follow the steps below:

• Improper shutdown process
  • Turn on your computer. When the Windows logo is visible, unplug the power source of your computer. Perform this step three times.
  • On the fourth time that you turn on your computer, just simply wait for the
    Windows Recovery Environment (WinRE) window to appear.
• On the Choose an option screen, select Troubleshoot > Advanced options > Startup Settings and click
  Restart.
• Once your computer restarts, you will see a list of options. Press the
  F4 key to start your computer in Safe Mode.

We also recommend that you perform a system restore after booting into safe mode.
This option takes your PC back to an earlier point in time. Restoring won’t affect your personal files, but it will remove apps, drivers, and updates installed after the restore point was made. To do this, follow the steps
below:

• Right-click the Start button, and then select Control Panel.
• Search Control Panel for Recovery.
• Select Recovery > Open System Restore > Next.
• Choose the restore point related to the problematic app, driver, or update, and then select Next > Finish.

Let us know if the solution above works for you.
