virus or hardware? some keyboard keys suddenly stopped working

  • tried almost everything; reinstall windows, change keyboard (ps2/usb) virus scans and changing motherboard all in vain. sa ps2 esc, left alt and spacebar yun may problem. sa usb naman mas worse k, i, 8 and arrow keys ang may issue. sa bios ayaw gumana ni usb kb, pero ps2 ok naman. im using on screen kb to type to this thread, yun mga kb and mouse ko sa ibang pc ayos naman. virus kaya or hardware? cpu i think is ok pero luma na din kasi (c2q-q8400). try ko na fresh install ng win7, 8.1 and 10 same pa rin. last week install ko 8.1 and issue disappeared sa ps2 kb, but usb persist. now bumaliuk yun problem need help guys thanks in advance.
  • bro meron akong ganyan ngayon, sa bios ok, uefi, pero sa windows, PS2 nawawala tapos bumibitaw pag sa usb tapos bumabalik.. nung nag try ako ibang PSU aba'y don pala, ewan ko kung anong meron, pero baka dahil generic lol

  • keyboard itself

  • try mo i run ung pc and remove cmos

    proc
    board
    single ram stick
    hdd
    tapos kb (wag mo muna saksak ung mouse)

    ung mga led light sa pc wag mo isaksak,

    pag ayaw pa rin try mo sa ibang socket dyan sa place nyo.

    Kung walang problema sa ibang PC yung mouse and kb, most likely busted (shorted) na yung USB and Ps2 ports connection from mobo.

  • hmmm you really did the list below?

    Changed
    1. Keyboard
    2. Motherboard
    3. OS
    4. PSU

    I can only recommend two things

    1. removing everything from the case and test
    2. Try Linux OS or an original CD and if it works ... alam na.
  • ok.tnx.will.try.all.suggestions^^
  • sa bios ayaw gumana ni usb kb, pero ps2 ok naman.

    Well then, mukhang sa installers nga ang issue. Di ata tama ang mga IRQ.

  • Di kaya grounded ang case? Same issue kasi kahit iba na mobo and kb. Mobo kasi iniisip ko pero sabi sa taas napalitan na.

    @mixmasta

    sir sige boot ko sya sa labas ng case, thank you wala na rin ako maisip^^
  • uu try mo nga sir floating system
    yung walang casing lahat nakahilata
    at one last thing pwede humanap ka pa ng usang Keyboard pa baka yung both kasi nasira somewhere na nag-a-isolate ka sa problema
  • well i tried all of your suggestions pero ganun pa rin.

    ang hindi na lang nasubukan is changing processor, kasi wala akong spare.

    anyway, salamat sa lahat ng nag reply sa thread na to.

    gonna reformat again baka ma fix ulit hehe

    God bless!!
  • grabe naman yan halos iba na setup mo bukod sa processor, pero parang anlayo naman kung sa processor bro, baka may elemento na diyan sa place mo hahaha
  • @johnpaulreyes

    after ng reformat, installed win 8.1 and a day or two; issue fixed itself hehe..

    i dunno kung ano yun problema, pero ok na sya ulit so far.

    salamat sa lahat ng nag reply sa thread na to^^

    God bless mga ka-TPC!
  • knew it.. elements.. hahahaha buti ayos na +1
