Upgrading a HP D4100Y Processor

Hello,

My D4100Y with a P5LP-LE motherboard is currently running a Pentium D. I researched the motherboard and found that the best processor the motherboard could support was a INTEL CORE2 DUO E6700. So I found on online and purchased it.

Upon installing it, my computer turns on, however I get no video output. So I shut it down, put the old processor in, and went into my BIOS. I reset the BIOS to default specs, and tried the processor upgrade again. Same problem - no video.

So I went out and looked at BIOS upgrades. I went to the HP website, and it says there are no BIOS upgrades for my system. I believe I am running a BIOS version of 3.05 or 3.06. Looking on the internet I see there is a BIOS update to 3.16 but it is not a Windows 7 BIOS update. I did attempt to install it, but the install failed.

I read a bit online that HP locks down their systems so you cannot upgrade the BIOS and thus the processors, but I am not sure if this is true. I am not running any software from HP - I started from scratch and installed a fresh Windows 7 Professional 64 BIT O/S some time ago.

So the main question is, can I get this new processor to work? Am I correct that the reason it isn't working is the BIOS? If so, I don't think there is any way I can upgrade the BIOS, since there is no way for me to revert to the original O/S. Thanks for the help.

TDP is thermal design power it is listed on manufacturer and retail websites, and the pentium actually uses more power so that probably isn't the problem, try without graphics card, remove it and attach monitor to onboard graphics port

The cmos stores the bios settings, clearing it will reset the bios completely you can try that a just remove the battery or use the jumper method it describes, it is more thorough then just resetting what you changed in the bios menu

Hp doesn't prevent processor upgrades, they wouldn't list it on their website if they did, however, they do stop releasing bios upgrades for older Machines which is pretty much the same as preventing cpu changes in some cases, but try what I've said then post back and maybe...

Do you have a discrete graphics card you can try? Maybe there is integrated graphics that the pentium can't support, try researching more did you check the tdp just because the socket fits doesn't mean the power is right

The Motherboard site specifically said this processor is supported. Here is the link:
http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00864946&cc=us&dlc=en&lc=en#N121

I am using a discrete graphics card to connect to the monitor, not the onboard graphics.

I honestly don't know how to check the TDP or ensure my processor is getting enough power, can you explain?

Also, I see on the URL I posted above that it talks about using a jumper on the motherboard to reset the CMOS BIOS settings. Is that something I should try? Is that different then inside the BIOS tool changing to the default settings?
