You will need to update the BIOS to its latest version to get rid of the microcode error, and the processor will only run at half the FSB speed because the BIOS update was not written to make the E7xxx processors work correctly.
You will need to run this software each time you get into windows and change the multiplier to the max.
Or you can run that batch file listed on the below webpage for it to run automatically.
If I were you, I would just install a Conroe E6700 and have a problem-free upgrade.
You will need to use the DOS based flash because I don’t think there is a BIOS update written for W7.

I did updated the BIOS from the HP site but the thing is that this E7200 is the same FSB as the original E6300 wich is 1066Mhz im not an expert on this so excuse me if i mistaking ��
the thing is that first time i’ve tried to upgrade with a processor with 1333FSB and i got something like 9 beeps and i’ve red about it and found out that is FSB issue so i returned that one and orderd this E7200 but now i’m desperate ��
I’ve red some posts on this issue for DC7800 i think where You’ve wrote about Microcode updates and now im lost in all this :S

You’re very welcome.
You should check the fsb speed of the processor in Windows. Forum members have reported it runs at only 533 MHz

Did the BIOS update get rid of the microcode error? It should have.
I see you added a new screen shot.
9 is the highest you can go?
If so, then you are good to go. 1066 MHz (System Bus) is the right fsb speed.

Here is all the info you need to update the microcode for your dc7800.
I zipped up and attached the utility to make a bootable flash drive below, the DOS command files you will need, as well as the dc7800 microcode update files.
You make the bootable flash drive first by running sp27608.
After the utility has formatted the drive and made it bootable, copy the DOS system files to the flash drive, then copy the dc7800 Microcode update flash files to the flash drive.
Copy just the files in the folders, not the folders.
Restart the PC with the flash drive plugged in, and the PC should boot to the usb flash drive.
The PC should arrive at a command prompt.
At the command prompt, type Flashbin.exe and hit the enter key.
Follow the on screen instructions to update the microcode.
After the microcode has been updated, the error should be gone.

Try resetting the cmos.
You may also have to reinstall W10 if you can’t get it to work.
I never had a problem restarting the OS when I updated the microcode on my dc7800.

Shut down the PC.
Unplug the power cord and everything connected to the PC. Mouse, keyboard, monitor. everything.
Press the power button to drain any residual power from the motherboard.
Near the coin cell battery there is a little yellow cmos reset button.
Press and hold that button for about 20 seconds.
Put everything back together.
Hopefully that will fix it.
If not try reinstalling W10.
The processor change may have messed up something in the windows registry.
If you have a W10 installation disk, you can try the repair options before reinstalling windows.
I don’t think it is the processor. If the microcode update error is gone and the PC acts normally until it goes to boot windows, then I think it is a windows problem.

Unfortunately, it gets stuck on windows boot screen and the screen only shows the windows 10 logo. It does not show the spinning cycle which indicates the window 10 in loading. Also, I cannot install new operating system neither from USB or CD nor I can repair windows 10.
Window I try to install window 7 just before I can see GUI the pc goes into blue screen and presents this message “IRQL_NOT_LESS_OR_EQUAL”. I have tired unplugging the graphics card and others connected devices but it had no effect but when I put back the old processor windows 10 works as normal without any problem.
