Hello I have a HP DC5800 small form factor - I did have on Vista 32 bit professional - I upgraded to Windows 7 Ultimate 64 bit and now have got this driver issue haha - I am in a bit of a bind and have not had any luck will somone please help me - under devic properties and details the problem code is 0000001C - hopefully someone knows the answer to this or a way around by dealing with it before

Hi:

Please post the hardware ID for the device that needs a driver on your dc5800 SFF.

If you don't know how to do that, please read the info at the link below.

You're very welcome.

Normally, this driver will take care of that device.

Hi, Paul!

While you're on the subject (dc5800sff); I had a little experience I'd appreciate your comments on:  The dc5800sff I had purchased recently (with the Win 7 Home Premium & restore disk; to jog your memory).  I got her fired up after receiving it (offline - always - until I've had a chance to tweak Security, etc.) - I had removed the 2.4 GHz E6400 and put the 3.0GHz E8400 I pulled (when I bought the Q9300 for the dc5800 MT) and 2 sticks of 2 Gig 800MHz Memory.  I put that project on "HOLD" until I get a book on Win 7(!) - all of the stuff I'm used to finding with XP has either moved, been renamed or deleted from Win 7 and I need to work with it when I have a little more time.

One thing that caught my attemtion while I had the sff running (w/o the bonnet) and with Piriform's, "SPECCY" running was having both a CPU temp and motherboard temp available to monitor.  On my older computers you usually get only one temp (or None, if you go back to 2005 or earlier!).  The CPU was running sweetly (as I had expected) at around 30C.  The Motherboard, on the other hand, was running in the mid to upper 40'sC (~46C +4 -2C), fluctuating with the demands of the software running - while the CPU's temp was very stable (~32C +/-: 1-2C).  I was curious as to the source of the motherboard's elevated temperature, as I've always correlated the motherboard's temp with the CPU being run and the accompanied heatsink/fan.  I had a digital temp monitor about 1/2 the size of a pack of cigarettes and just set it atop the Intel Southbridge I/O Controller (Intel 82801IB  SLA9M).  With no thermal coupling (e.g., 'grease') the temperature was measuring over 40C and the Power Supply was making a "morse-code" kind of noise - I isolated the noise to the power supply because when I rocked it upward 'out-of-the-bay'; the noise dissappeared.  I believe because the noise was being amplified via a hard to hard contact with the enclosure, in that tight knit sff configuration.  Intel rates the I/O Controller:  NH82801IB as having a TDP of 4.3Watts with a Tcase of 96C (!!!) - Is this correct?  I'm amazed it doesn't have a heatsink!  What are your thoughts?

                                                                                                                        Kind Regards,

                                                                                                                                                            wfejnieh2

Hi:

All is can say is wow...you're really into the thermodynamics of your PC's! 

I have to confess that I have very little knowledge of these issues and I just figure if the CPU fan is at idle, life is good.

I think I used one of those free programs to check the temp on a hard drive once because I read that if the temps run over 40C, that degrades the drive's reliability, and if over 50C, that just ain't good at all.

I think that heat is an issue with small form factor PC's and it has to be exhausted out quickly and efficiently because the buildup will be swift and detrimental if it can't be dissipated.

I agree with you that a Tcase of 96C (almost the boiling point of water) is up there!  But I always thought that to mean that was the upper limit of tolerance, not the normal operating temp.

I'm afraid my ignorance shows you how much I know about these things.

Best Regards,

Paul

.........Paul; I'm not going to touch your commenting on your level of knowledge .........

Intel's spec page on the Southbridge Chipset, http://ark.intel.com/products/31892/Intel-82801IB-IO-Controller

might contain something useful.   Why did I recognize this temperature as a noteworthy 'event'?

The computer was operating with all hatches spread wide open - the dvd rocked forward; the power supply rocked backwards and with the lid off!  The dc5800 MT's have the exact same chip!  - Right now, I'm on the dc5800 MT (all buckled up) and the 95Watt TDP Q9300 is running 41C (remember - the E8400 3GHz it replaced was only 65Watt TDP!  the Q9300 using ~50% more "heat producing" Watts!  The Motherboard of the MT is now only running 36C. 

What-ever is causing that sff's high motherboard temperature can't be blamed on the CPU! and it can't be 'explained' away as being high merely because it's a "sff"!  Not 'wide open' like that!  Something is wrong with that sff!  That "chip" (Intel NH82801IB) alone could have (and probably was!) heating up the whole motherboard!

W/O further testing; I'm thinking Either the Power Supply is going bad or I have a bad motherboard.  It's NOT running within the "norm".  I thought you might be able to help direct me.  Could "Software", i.e., out-of-date Drivers, or BIOS cause Temperature issues?  That's why I told you about swapping out the Core 2 Duo E4600 (2.4GHz/2 MB/800 MHz) it came with, with the Core 2 Duo E8400 (3.0GHz/6MB/1333MHz) processor; and it came with 2 - 1GB 800MHz Memory which I pulled and replaced with the 2 - 2GB 800MHz Memory --- all done before   I fired her up!  If any one's listening:  Get a "starting Point Reference" buying used equipment Before  you make any changes!  The changes I made would have voided any warranty that might have come with the system!  My over-enthusiasm overwhelmed my common sense!  Now I'll never know if that computer arrived "Broke"; or did anything I did/didn't do "Break" it!        Regards, and thanks (as always!) for your help, Paul!       wfejnieh2

Hi:

I now agree that something is amiss, but I wouldn't know what that would be.

Now that you have explained that you have the PC "vented," which shouldn't be necessary, there is something out of the ordinary causing the heat buildup.

I checked the specs, and the Q9300 is supported in the SFF, so it isn't that.

I can't think of any software or drivers that would cause that.

I would think if the power supply was defective, you would feel the heat coming out of that and not the mainboard area. Not to mention if it is over producing, it would probably kill something on the motherboard, not just get it hot.

I don't think updating the BIOS would matter. Did you read all the version's release notes to see what they address?

That is about all I can throw out there.

Yes, without a point of reference before you changed the processor, it is hard to say what it's before state was.

I doubt adding memory would do anything to cause the heat buildup.
