I have an HP Pavilion a1473w desktop, which came with a P4 2.8 GHz cpu. The specs on the mb, which is an RC410-M (Asterope), with an ATI X200 chipset, says that it will support, among others, a Pentium D 9XX series (Presler) cpu. I bought a Pentium D 945 3.4 GHz cpu, with Intel heatsink, and installed it on the computer. But after the computer starts up, it shuts down in about 5 secs. After being told numerous times by the tech "experts" at HP that the computer would run this cpu, I went ahead and bought it. But I tried to install it twice, and both times the comp would not work with it. Does anyone have any suggestions here?

ps. I also installed a Vision Tek x1550 PCIe card. Would this make any difference?

have you tried to reset the bios? should be a battery on ur motherboard take it out and wait unplug the computer from the power, wait about 30 secs and plug back in, this will erase everything in the bios

No, I haven't done this. I have updated the bios, but haven't
tried installing it again. Thanks for the suggestion. I'll try it.

It is possible that the problem is overheating.

I don't think the Presler core is as bad about heat as the "pressed hot" ... oops I mean Prescott core, however heat may still be a factor.

Would you suggest a reinstall with a better heatsink and
application of thermal grease to the cpu?

by older mycroft

It may have little heat dissipation abilities, and the cpu is shutting down as a precaution.

by maharris1957

Since this is an Intel boxed cpu, with attached heatsink, I
followed the Intel instructions. The stock Intel heatsink had a
thermal pad, and instructions said not to attach thermal
grease to the cpu. So I didn't. I simply plugged in the plastic
caps of, the apparently crappy , Intel heatsink, and attached
it to the power connector on the mb. The fan started up
when I powered up the unit, but shut off after about 5 secs.

Even the stock Intel heatsink should cool enough to at least let the computer boot up and run.
Being this is an HP I doubt there are a whole lot of overclocking options (if any) in BIOS. One of the other suggestions was to reset the BIOS, have you tried that? Updating the BIOS won't necessarilly reset the BIOS.
You mention the Vision Tek card, did you install this card before updating the CPU or at the same time?
I presume when you try starting the computer you are allowing it boot up to the OS, Have you tried just going straight to the BIOS? Does it still shut down when in the BIOS screen? Some BIOSes have a health page with CPU temperatures, I don't think HP does but it's worth checking.
Since you are having problems booting with the Intel D CPU, in order to look at the BIOS you may have to go back to the P4 chip to do any verifing of the settings.
You may also want to verify that no pins on the CPU got bent during install.

Yeah, maybe try a different heatsink and grease, I would kinda want to run through as many options as possible before spending more money ($50 - $70) on the massive heatsink this will need. Oh, and hopefully it will fit in the case and work with the motherboard. You'll definately want to do your reasearch before buying.

Somehow my reply ended up in another discussion. Yes, to answer your question, I installed the X1550 before trying the PD upgrade. Thanks.

If it isn't I can maybe suggest some more ideas.

I have the They a HP a1473w also . I read You?re posting on TechRepublic. And I would like to upgrade my computer with a new CPU. I was wondering if you got your is to work . An what did you do to get it to work . I?m just a carpenter so help me out here on how to do this thank you ronlramsey@cox.net

by maharris1957

Thanks for your reply. I have not gotten the PD to work yet. I have not had time to mess with it yet. If you read my post, you probably read the other excellent replies along with it. If I decide to ugrade the cpu, I will reset the BIOS and throw down for a heavy duty heatsink. The Pentium Ds are flame throwers, I understand. Upgrading a cpu involves more than just throwing a new one in the unit it seems.

In order to upgrade your unit [which is a very good desktop unit, by the way], you might want to put the maximum ram in it, which is 2 gigs. I did this, and it made my pc much more responsive, and faster. And it is much easier than upgrading the cpu.

The P4 2.8 GHz which is in the unit is a pretty fast processor, actually faster in single core applications than many of the dual core cpus, and it functions as a virtual dual core, since it supports hyper threading technology. So you might want to do this first before you upgrade the cpu. You can check the system specs on memory on HP, or go to crucial.com and find out what types of memory the unit requires, which is non-buffered DDR2 of various speeds.
