HP dc - Recent Questions, Troubleshooting & Support


That "PCI Serial Port" is probably part of a PCI modem that is connected into a PCI slot on the motherboard.

Access the manufacturer's web-site: http://support.hp.com
and enter 'dc7700p' and do a search for device-drivers for your computer.
Download the device-driver. Install it.

5 beeps = Pre-video memory error which means that the northbridge on the motherboard is faulty. You need a new mobo, this one is dead.

HP Compaq dc7700... | Answered on Feb 03, 2019


NO!

Two Netburst based Processor cores on the SAME chipset?

Get outta' here!

When did they come up with that?





OH, I'M JUS KIDDIN'!

http://h18000.www1.hp.com/products/quickspecs/12145_na/12145_na.HTML

The HP Compaq dc5100 Desktop PC uses an Intel 915GV motherboard chipset.

Since we know that the Northbridge chip, of the motherboard chipset; handles the Faster capabilities of a computer;
i.e., Processor, Ram Memory, and HIGH-speed graphics; let's look at the Intel 915GV chipset,

http://en.wikipedia.org/wiki/List_of_intel_chipsets#Pentium_4.2FPentium_D.2FPentium_EE_chipsets

No sir/ma'am.
The Intel 915GV motherboard chipset only handles Single Core processors;
Intel Pentium 4,
and,
Intel Celeron,
and,
Intel Celeron D.
(With a 533MegaHertz Front Side Bus, or an 800MHz FSB)

The Celeron D is NOT a dual core processor,

http://en.wikipedia.org/wiki/Celeron#Prescott-256

"The D suffix actually has no official designation, and does not indicate that these models are dual-core. It is used simply to distinguish this line of Celeron from the previous, lower performing Northwood and Willamette series, and also from the mobile series, the Celeron M (which also uses 3xx model numbers) Unlike the Pentium D, the Celeron D is Not a dual core processor."

Yeah, I know. I'm just a 'Ray of Sunshine'.

You know you can pick up a motherboard pretty cheap nowadays, that WILL support the lowly Pentium D, for not much money.

Problem is you will need to replace Ram Memory also.

By the time you get a motherboard chipset that supports dual core Processors (CPU), you are going to be using DDR2 Sdram ram memory, instead of the DDR Sdram ram memory you are using now.

OK, Motherboard, CPU, and Ram Memory.

Oh, the Power Supply. Won't do either.
240 Watt unit, or 300 Watt unit?

Sure.............OK.

Back in the day those Power Supply's were made, Power Supply manufacturer's were 'fudging' the actual maximum rated Wattage.

True Wattage was more like 60 to 70 percent of what was stated.
Why?
SOLD more Power Supply's.

240 Watts?
Simply divide by 10. = 24.
For 60 percent, take 60 times 24. = 144 Watts
70 percent? 168 Watts.

300 Watts?
60 percent is 180 Watts.
70 percent is 210 Watts.

I wouldn't try to run a Barbie doll with that low a Wattage, of Power Supply. (Barbie doll? What?)

Need at least a decent 350 Watt power supply, from today's manufacturers.
80 percent constant duty cycle, for most good units; or higher.

So...............
Max out the Intel Pentium 4 CPU.

4GB's of 533MHz DDR Sdram ram memory.
(PC4200, or PC4300. Depends on the manufacturer as to how they name it)

By the time you spend that much money, you may as well buy another Motherboard, Processor, Ram Memory, and Power Supply.

Yes, may as well buy a better computer.

I know. Quit trying to cheer you up.

Around here we have Craigslist, and Ebay, for two places.
Could pick up a better computer, for around the same money, as you would pay for all the upgrade parts above.

Which is better? Upgrade the Processor, or upgrade the Ram Memory/
For the better 'Bang for the Buck', upgrade the Ram Memory.

The CPU (Processor) has a built-in cache.
L1 cache, and L2 cache. (Newer CPU's have an L3 cache)

The Cache is a small memory area for the CPU.
It is the FIRST memory area the Processor (CPU) reads.
This is because it operates at the same frequency rate, as the CPU does.
(Frequency rate = 'Speed'. Operates at the same 'Speed')

Next inline is the Ram Memory.
Ram Memory -> typically, operates at half of the Processor's Front Side Bus. (FSB)

This is why upgrading Ram Memory is a good idea.

It isn't so much of getting Ram Memory, that operates at a higher frequency rate ('Speed'), as it is to have MORE ram memory.

Example;
PC3200 compared to PC4200.
4GB's of PC3200 is better than 2GB's of PC4200.

(DDR Sdram at 400MHz = PC3200)

Moving on............

Motherboard chipset:

Chip and Chipset are slang terms for I.C.
Integrated Circuit,

http://en.wikipedia.org/wiki/Integrated_circuit

The motherboard chipset for your computer, consists of a Northbridge chip, and a Southbridge chip.

{Motherboards that support the Intel Core i technology, (Core i3, Core i5, Core i7, etc), do NOT use this motherboard chipset technology. Neither do some of the AMD CPU's }

http://en.wikipedia.org/wiki/File:Motherboard_diagram.svg

As stated previously, the Northbridge chip handles the Faster capabilities of a computer;
Processor (CPU), Ram Memory, and HIGH-speed graphics.

The AGP technology, and the PCI Express technology; ARE high-speed graphics.

Using a graphics card in a PCI slot, or using Integrated Graphics; is NOT high-speed graphics.

The slower capabilities of a computer are handled by the Southbridge chip.
1) PCI Bus / Integrated Graphics.

(Another term for Integrated Graphics, is OnBoard Graphics. A term that seems to have gotten lost.
It explains better; ON the motherBOARD )

2) IDE Bus
3) SATA Bus
4) USB Bus
5) Ethernet
6) Audio (Sound)

Point?
Look to see what the Northbridge chip is, as I have shown you; and you'll get a good idea of what Processor (CPU) support is.

For additional questions please post in a Comment.

joecoolvette

(I get tired of looking on websites, that just say NO, and do not explain why )

Hyjacker, Ransford decker ask 6 years later.
ahhh , old BEEPs codes so old that HP even forgets them
over 10 years old./ yours is now 13 years old
first off is the Motherboard RTC coin cell dead, as all are this old?
replace it first. a wise choice. that.
on some HP code 8 is coin cell dead. did you count flashes wrong? the count matters. big time....

on AMI BIOS code 8 means
Display memory error (system video adapter)
later AMI BIOS code 8 means.
ROM Checksum Error
ROM checksum value does not match the value encoded in BIOS.
this means COIN cell bad again.

i see no code 9,s in my huge private lists of bios codes for 20 years.
ok , reading all manuals, on this one PC i find this.
"System not fetching code"
now there is classic geek code, wow.
my guess it means CMOS ram is corrputed.
again the coin cell is bad. table.(fixha wrecked it, sux, no?)

why run dead XP?, is the PC ONLINE? or off/?
The USB plug and play is failing,
you do know MS killed dead Plug and Play for XP 4 years ago right?
the top failure of any pc running XP would be USB devices.
USB devices are extensive in scope, endless types
and top of the list are mice, and keyboards.(vast types exist))

The PnP engine scans the local driver cache first.
if no mouse (example 1) is found to match your unstated mouse
then it must do what? go on line, to MS.com
and MS pulled the plug..... just like they did
on
w95
w98
ME
W2000 and vista. and XP 4+ years ago !

time to upgrade, for sure.

a counter argument would be that the virus magnet XP is infected.
as ALL ARE NOW and worse every day forward!! for eternity

win xp is so far out of date that the drivers in that operating system are not being updated by Microsoft
Any other glitches are also not being fixed
win 7 is also no longer being supported by Microsoft and many of the drivers in it are starting to show faults
Suggest that you consider win 10 as Microsoft have already given a time for win 8 and vista as to when support for them will also stop

One question, my computer has 4 slots(mem) and I put 1 GB in each slot is this model DDR2-800MHZ-CL8 PC6400U. the question, if? the computer presented a problem with time?

to do this and the last I would like to know what video card? I can put it and how much mega(bytes) can the computer scare? me.

dc7600 (12 years old)
NO OS stated. (XP,VISTA, W7/8/10) 1st came with w2000

you posted to
dc7600 Convertible Minitower PC Desktop , Pentium 4 at best.
800 MHz front side bus.
Dual-channel DDR2 667 memory. 4GB max !

if this is correct, (most are not, due to lack of fixya variants)
then.
PCI Express™ x16 , slot.
the spec page says it has this slot. so most new video cards
will run in this slot but not over 75watts unless the PSU is upgraded for powerful fast GPU cards with its own power cable.

when new this card was an option over a decade ago
ATI RADEON X300 SE PCI Express 128-MB DDR single head DVI with TV out

they offered 4 vidoe card choices then.
the PSU is 364watts. (marginal for any fast new Video cards)


simple answers:
  1. only you memory seller can match up correct memory types DDR-667 or faster. like Kingston, as them !!!
  2. 4GB max mem.
  3. lacking correct PSU only 75watt Video cards work or less.
  4. with correct PSU the sky's the limit,!!! on power.
why upgrade such and old 12 year old system.
are you dreaming of running fast $60 games? it wont work.
it's too old.
tell why you need the video card first?. usage matters first.

Download and install and run this. You may want to go to the settings tab in the program and change it from metric. Then you can see the temperatures of everything in your computer. You can then launch the game and see what the temps do. It is common for fans to speed up when the computer senses large demand on the processor and graphics cards.

so what is the 1st drive, and is it IDE or SATA.
or is one a
why are you using XP is it 32bit or 64? ill answer for 32..
its a dead OS,totally dead,and virus magnet and the MS PnP severs are shut down.
XP also MUST have the SP3 installed or the THING cant find any modern, SATA chips and many other devices.
im looking at your MOBO now,
it has 4 sata jacks
1 floppy
and 1 IDE jack let me guess this is what Drive one, IDE (pata)
is plugged in , then you add a new sata drive to the old sata ports
and XP pukesssss, as all XP does (cept mine)

SSDD. Same stuff different day,
so you can either use w7 like all savvy folks do
or find the driver missing that MS cant find, XP is dead.
but wait XP needs a Floppy drive to load the correct driver.
but if XP is running now, we dont need that only on XP installs.
ive no idea on what sata chip is there, in our shop
we scan it to find that and HP does not tell this.
Pentium D processor
Intel 945G Express
i think this is it , the 945G
load this driver from HP

Make sure your Sata connection start from Sata 0 and on up. You'll get the 1796 error when you have sata drives or devices plugged in other sata connections, Like: Your first Hard drive in sata 0 your second drive in sata 1 your optic drive in sata 2....You system (BIOS) will automatically start at sata 0 then sata 1 and so fourth.

hope this helps ya and thank you for using FixYa.
