20 Most Recent HP Pavilion 734n PC Desktop Questions & Answers

Your CPU may not be getting power. You need to start there. verify the plug is plugged in to a known working recepticle - ie plug a lamp in or your monitor for that matter - exact same plug. Once sure, then verify your power supply switch has not been switched by accident. get a light and look physically at the back where the fan is. The switch is obvious - with a 0 or a 1 - the 1 needs to be pressed in. If the CPU still wont turn on, then the power supply is likely bad - especially if no beeps. If this is the case, you need to replace the power supply. I would take your cpu in to get checked as you may have blown your cpu completely and you dont want to buy anything for a dead motherboard.

unplug it for a minute then try maby sometings loose or its just dead

The beeps are Power On Self Test (POST) beeps. Research them on the web, but here is a quick list.

if the cd drive is bad replace it...if there is a disc that you need you can open it with a paperclip...gather up a paperclip (or something close to the same size) if you look on the front of the drive there is a tiny hole...unwind the paperclip straightening it out and slide the paperclip in the hole...it should open with no problem

You can get this adapter from Linksys its WMP54G so you can make the computer wireless, but you can also check some adapter from Ntegear , Belkin and Dlink...

i think it slides out the front

no pc told, Pavilion means zerothat name is is used on desktops and laptops for agesthe HP has diagnostics so run those. HP.com tells how.not told desktop or laptops. just 1 word."Screen"first Pavilion was 1995

HP.COM << go there. And ask a real question ,you did not.

learn to google mate. this is no secret,gee millions sold. A6Y530A the partsurfer shows true model, and fails this is the only post here ever asking for reverse code lookups on models fake, and is not easy in vast cases I guess you have no such PC, (look like) so why ask this>? what prompted this quest>? not told why not ask seller for photos of it if this is a pre sales question , is it>? google and bing and HP all show that model # is BOGUS so go back to your sell and ask the we can not guess PCs ever. HP product ID# is best on the service tag for SURE. where did you see this number, not told. or that number is some 20+ year old COMPAQ PC ,lost in the sands of time, and no google hits. you posted to HP forum, (not real) Hp.com is real

what does not working mean (KBD) dead, or 1 key bad or row. what? symptoms matter most, for sure in a LAPTOP IS IT the word Pavilion is on laptops and desktop, dig? G mean zero , the service tag does not just say "G" sorry. easy peasy lemon squeezy HP.com complex URL no? go there tell them your model # or better the service tag code ! . then magically HP puts you on YOUR service support page and all manuals and all driver before your eyes. amazing no? NO told at all or of a laptop or desktop or what./? you posted ANON so I can't just read other posts by you to learn what PC this is , no I can not. there are over 100 PC called G series, and vast years. some PCs by them G1 to 7 are generations, like HP Pavilion g6-1029tx Notebook. if you can find the service tag the product ID # is what matters most this code includes (real model, version , options and country sold) see this, older PCs by them had this. see that , all matters but do not post SN/ or service codes in public. mine: procuct code (nnnnnnABA#) https://www.pcdied.com/TAG-jive/tag-elite8540w.JPG I will guess it is 17" laptop, here is the mess just that 1 sized once you see this you know that G series means not MUCH> https://search.brave.com/images?q=hp+G+series++pavilion++17%22+G&source=web

old PCs do that, for many reasons. but no PC told at all just HP. 40 years of PCs ,10000 + models nobody can guess ever. but I do have the answer, in pure generic form. did you buy the PC like that used and bad Wifi. ?

1. the wifi card is missing, as was super common 10+ years ago.
2. someone put in the wrong card, not from HP list
3. HP blacklists (bios blocks) none HP cards (wifi)
4. the card needs a driver to work if not it is dead or 1/2 dead.
5. the PC needs 1 more driver to make the wifi buttons all work , all buttons related, if not they are dead or act odd.
6. The OS is infected, no OS told at all, not one clue nor if upgraded the OS, and not vast drivers are wrong or missing, (classic)

Im sure this this is not the free w10 upgrade, if it was that too kills drivers dead, for sure HP told you this unstated PC will not run W10 and has zero support from HP, on w10 AS YOUR SUPPORT PAGE WILL DISCLOSE TO YOU AT HP.COM

today there are many PDF , Viewers not juts Adobe ! google finds them like this. https://www.google.com/search?q=pdf%20viewers

bad news now your bricked it just like miillions did google bios update bricked my PC and cry. why are you here and not at HP.com only they can recover bios. they changed the rules now 10 time. so only they know this, and are pain to deal with. UEFI is the enemy here, new rule and regressive as can be. in fact all new PCs can not be regressed, and some old now they even delete the 20 version of bios there, to force that. not saying they did that to your PC, but keep that in your head on all HP PC. the last bios upgrade stated, no going back. the Cntrl_+B might work , the flashback bios trick\ in your manual if you read it.

nobody can we erase all and reload the OS fresh. did not say you can not try but that 99 out 100 will fail.

100% dead black screen no text or HP SPLASH screen now. The problem is hardware where we buy hardware for free, less than at deity level or a thief. you tell me.... no PC told at all not one tiny clue of 1000s of HP models for 4decades are we to guess models and lie to you? now the GENERIC answer USA PCs only sorry I do not do others. fans dead? no beeps> codes no Caps lock key blink codes. no text errors.? 1: does PC run BIOS pages if huge now shorted old relic battery is removed ,yes bingo 1. 2: is the RTC coin cell dead, ,Bingo 2. a $1 uSD ,USA cost. here. 3: the pre 2010 all have bad CCFL lamps; do this flash light test? https://www.pcdied.com/monitors_and_screens/flash-light-trick.html#flashlighttest if yes, that is a $50 to $100 USD parts repair , labor more. repairs are serial process, as fixing one thing bad ,uncovers the next this is how mans machines work just like that.
