How to fix "1801-Microcode Update Error" in HP tower desktop Compaq dc7800

[Mobeen2017]

I have made some kind of break through but I am not sure if I am happy about it though. So I went ahead and dual booted and installed the E8500 and at first I was getting same error but then I tired safe boot and it worked and I have looked through the minidump files and found this information. I am hoping you may shine some wisdom on this problem.

Unfortunately, I don't have any idea how to read those files.

If it's not a hardware issue, I just clean install Windows when I get software errors.

I cannot install new windows 7 os due to as soon as i go pass the loading screen of installation i get the error and blue screen but i have asked around on other online forums and got told to install ubuntu which i did and it works find with both new cpus which begs the question what the hell wrong with windows OSs.

It does beg the question, and unfortunately, I don't have an answer.

The processor you upgraded to should have had no effect on Windows not working/installing.

Well you never stop learining and this was valuable experience for me so thanks for sharing this journey with me.

UPDATE:

I have managed to fix this problem by updating the 1.04 bios of 2007 to 1.35 bios of 2015. Also I have tired to update the bios before when I had windows 10 installed and I have read that HP does not support windows with their bios update tool. After updating the bios I have installed the E8400 and it worked like a charm.

BTW I am think of looking into further CPU upgrades and I have found the infomation on this link and the motherboard supports these upgrades options.

I do not understand the meaning of Y W K and I am not sure about which processors are supported.

1. Intel Core 2 Quad (Y) Q9xxxx
2. Intel Core 2 Duo (W) E8xxx
3. Intel Core 2 Quad (K) up to Q6600
   This infomation is not irrelevant since my cpu is higher then these.
4. Core 2 Duo E6x00 (C) up to E6700
5. Core 2 Duo E4x00 (C) up to E4400

If you can help me figure the cpu supported or find a list of them that would be great.

Thanks

That is great news.

Here is the list of supported processors for the dc7800...see page 9.

Thanks

I have looks at the specs of a q6600 cpu and it FSB is 1066Mhz and e8400 FSB is 1333MHz. Do FSB speeds matter and will motherboard can work with different cpu fsb speeds.

Hi:

That motherboard can handle 3 different speed processors...800, 1066 and 1333.

Why not go for the gusto and get the best quad core you can?

I doubt the Q6600 will be much better than the E8400 you have in there now.

[Mobeen2017]

Im working on it because the quad cosume 30 more watts of power the psu will blow up since the current power est is 217/240 another 30w would push the power to its limits and most likely go over 240w. 

So I have ordered new ACE 600W PSU for £20, I know its cheap but these only cause problem when u push them to their limits or 20% close and since I will be using half of 600w hopefully I shouldnt blow up the psu and burn the house down with it.

As you know that HP SFF case psu is not upgradeable so I have also bought ATX case to go along with the new psu and once there both arrive all I need to do is move the motherboard with cpu and ram slots in it to new case and hopefully everything should go as plann and then I will go for the top quad core support which is Q9550 which has same front side bus of 1333Mhz same as E8400 so ill keep you posted.

Thanks
