HI Good day!! do the following
Disable Deep Freeze before uninstalling it.

To disable Deep Freeze:

1. Hold down the shift key and double-click the Deep Freeze icon. Alternatively, you can press CTRL+ALT+SHIFT+F6.
2. Enter your password and click OK.
3. If you have not yet entered a password you should be able to click OK without entering a password.
4. The Boot Options dialog is displayed. Select "Boot Thawed" and click OK. This will disable Deep Freeze on the next reboot.
5. Reboot your computer. After the computer reboots, you are ready to uninstall Deep Freeze.



To uninstall:

1. Locate the installation file you used to install Deep Freeze on your computer. By default, the name of this file is called "DF5Std.exe" for versions 5.X and "DF6Std.exe" for versions 6.X.
2. Run the installation file (DF5Std.exe or DF6Std.exe).
3. Select the option to "Uninstall"

Deep Freeze is uninstalled and your computer is rebooted.

OK.

Thy to identify RAM, remove it and clean the contacts with a rubber (the same you use to erase the pencil marks).

Put the RAM again and try to boot.

-------------------------------------------

Another problem can be the temperature...
Remove the fan (and clean it)
Remove the heatsink (and clean it)
Put new thermal compound


put back the heatsink and the fan (connect the wires)

check your temperature in your BIOS

Best Regards

your vc might be heating up, try to remove it agai. take the heatsink out and then put a thermal paste on it before returning it on the vc, then install it again and see if that will works.

The compressor is overheating and not starting. Could be just the start relay. If this happens again try unplugging it for about an hour then it should work for a while. Heat between doors is normal this is an electric heater designed to keep the doors from sweating. You just noticed it because the refrigerator wasn't cold.

Well start a bit slower then.
go into the bios at startup F2, and navigate around does it freeze there. if no then
start windows in safe mode F8 when windows logo shows.
freezing ?
If its not freezing then turn off the startup programs.
Start/run/msconfig and then uncheck load startup items
and start normally, click the dont show me this again /ok
any freezing.
If its freezing you may have a hardware issue.
if you have 2 sticks of memory remove on and or /reseat them
boot the dell diagnostics cd and check the cpu and memory.
report back

remember only one can burn at a time
