Question about HP Pavilion A642n (PE544A) PC Desktop

2 Answers

Can this be saved?

Hello,

We recieved an HP pavillion a642n from a family member and tried to add a new gig of ram because it was limited. My brother installed it - he has never had a problem before.

The computer flat out refused to start. He removed the gig and now it starts running automatically when the power is turned on (not the power switch, but the outlet power) you can turn it off using the button in the front but it sounds labored and the dvd and cd drives are slow to respond opening and closing. There is no response to the monitor while the tower is running.

Since this is not our computer we would like to salvage it, but it depends on what we need to do. It has been suggested that we need a new motherboard - what type would this be? Any help would be appreciated.

Thank you ver much,

Mary

A replacment motherboard sounds correct but to find out the model most manuf. did not post the model on those mobos, there may be hope though I would look around the mother board for a model number still you could maybe find a good used one on ebay. if no model and the mobo will be replaced anyway take a look at what ram you have take off the heatsink off the cpu big metal & fan on top left of mobo most of the time under there will be a bracket with what type of cpu it is (a exp being pga 478 / socket A or socket 462 etc then look for a motherboard that will accomadate both ram and cpu reinstall windows from an oem disk (find one at a local repair shop $20.00 to $50.00 us) new mobo will / should come with drivers used (may not / usually not)

or you could replace ram, cpu, & mobo with a "combo kit" from tiger or neww egg and get a good upgrade

Check that the memory be the right one.
Check that the memory module be sitted correctly into slot
Check your video card (be sitted and configured correctly in your bios)
Check the monitor cables and VGA connector at the back of your computer
Check your CPU (be sitted correctly)
Check your power supply.

If still the problem continues need to replace your motherboard.
Take the motherboard number and model written on the board
With this number you can find your replace.

You can also repair your motherboard

But usually is better to get a new computer instead of repair an old one due the cost or time required to get the parts.

Hope this helps

Have a great day!
Pablo :-)

Bought 2 gigs of RAM but Pavillion NY801AV-ABA p6100z doesn't recogize it.


I hope I can help!
Now, without knowing exactly what kind of ram you purchased, I cannot tell you for sure what the problem is, but this is the most likely, and most common problem. That is to say, your computer probably does not support whatever kind of RAM you purchased for it.
There are Multiple kinds of RAM (DDR, DDR2, DDR3 - not including older variations), and many different speeds. Each motherboard in every computer can run only certain kinds of RAM, and supports certain speeds. Sometimes a motherboard will support multiple speeds, but some are more limited.As far as the type, most motherboards will only physically support one type, so that should not be a problem as any other kind simply should not fit. Looking at the specs of your computer, it is also possible that your computer limits the size of a stick of RAM that must be placed in each spot (It looks like you cannot have a stick of less than 2 gigs in any spot). That is probably not the problem as you purchased 2 gigs of RAM. It should also be noted that your computer supports a maximum of 4 gigs of RAM.
All of that being said, the most likely problem is that you accidentally purchased the wrong speed of RAM. Looking at the specs of your computer, the only speed it supports is DDR 2 PC2 - 6400. It would probably be best to return the RAM your purchased and get some DDR2 PC2 - 6400 RAM. If this does not describe your problem, or if there is more to it, please ask!
I hope that helps!

My hp a642n won't boot from any media. I inserted


old PC, very very old, and no mention of what media
i can thing, of many,
HDD,
SSD
CD
DVD
Floppy
BR-D
zip drives (1994 to 2003 era or more...)
USB sticks.
boot from net drive. (thin net)

I guess you meant the HDD boot tied, or HDD OS is dead from virus
so tried to boot to a CD? to fix it?
or ? I can think of vast other reasons to boot from non HDD but
why must I guess this>

What are you doing./?
or post symptoms?
best i can tell (unsupported product )
is it had VISTA when new.
my guess VISTA is SICK?

a642n instead of a6242n
is it really the one on the left here?

the a642n is obsolete and old
what is there now , who knows, it can be even upgraded extensively
or not. (looking at the guts inside tells me that , eyes on it)

HP Pavilion a642n Desktop PC (says retired, like me, LOL)
https://support.hp.com/us-en/retired-products
searching for facts , on this old PC wow, obscure is the word
it seems " 3.11 (13-Sep-2004) BIOS last release"
its, 13 years old, Id retire it. find a 2010 or newer box.
but do say what you attempt to do and what media is it.?
both type of media and CONTENT.
good day and good luck.

I just got an old HP Pavillion a335w, and it seems to work fine, but even with a new video card I can't get any thing to display on the screen. I have seen it for a few seconds, but then it goes blank on...


I have a Compaq that came with this board and a celeron 1.8 or 2.0 I believe. The fastest P4 that will run is a Intel Northwood 2.8 Ghtz 400 FSB nothing ELSE! Northwood 2.8 is the fastest 400 FSB, the boards chipset won't run anything faster than 400 FSB. Mine is running, Win 7 the Northwood P4 2.8 with 2 gigs ram, 160 gig HD and a 256 video card for over 5 years (minus win 7, had XP before with no issues. Good for light gaming, web surfing and MS office! Add a Zotac 512 MB PCI or Sparkle Video card and you can handle most more medium gaiming out today! My cards have HDMI and DVI output. I highly recommend it!

HP N5495 can I get another motherboard that will support 2 to 3 gigs ram?


Hi,

Sorry but the answer is no. Laptop motherboards are specific to a certain model of model family.

All the HP models in that family only support 1GB of ram (2x512MB)

You would have to purchase a new computer that supports over 2GB of ram.

nope....that 2 gig is true..and the reason it may be invisible is that it is not seated properly, or, it is mismatched..
