Computer beeping when booting up after installing GTX 750 ti

Hello, i just bought a gtx 750 ti 2gb superclocked. I have a factory HP h8-1202 PC. This is the first time i have ever taken anything/ installed anything in my computer. Everything seems to be in place, but i get these short beeps when i boot up my computer, and my monitor powers up, but then it goes to sleep. I didn't uninstall my drivers from my last card, a gt 520, and i don't know how to update bios. My friends told me i don't have to uninstall old drivers. I want to know how i can get my computer to work? or if it is an issue with my motherboard. Any help would be much appreciated.

Here is my computer : http://h20565.www2.hp.com/portal/site/hpsc/template.PAGE/public/kb/docDisplay/?sp4ts.oid=5187019&spf_p.tpst=kbDocDisplay&spf_p.prp_kbDocDisplay=wsrp-navigationalState%3DdocId%253Demr_na-c03173335-15%257CdocLocale%253D%257CcalledBy%253D&javax.portlet.begCacheTok=com.vignette.cachetoken&javax.portlet.endCacheTok=com.vignette.cachetoken

  1. Did you try putting the old card back and starting it up again?>
  2. Hm, it shouldnt be a driver issue since it didn't even boot.
    Try resetting CMOS.
    Remove the bios battery for 5 mins(with pc being off) then put it back in.
    Or check your pc/mobo manual for the jumper you need to short in order to clear CMOS-most mobos have one.

    Yes, it works fine with the old card in
  4. I do not trust HP's and after market cards... They are not Gaming built systems and suffer accordingly.

    Oh yeah... the new card requirements: 400 watt or greater power supply with a minimum of 20 amps on the +12 volt rail.

    Most HP's come with 250 or 300 Watt PSU... that may be the real issue... If it is not at least a 400Watt PSU, stop now and get a 500 Watt PSU.


    If it is a strong enough PSU:

    Uninstall the Nvidia suite and reboot with the old card in it, make sure it boots up on the Windows default drivers. If it does, go to the Device Manager and "Uninstall" the Video Card. shut down and place the new one in...
  5. Yup, according to the HP support page you have a 300w PSU. EVGA said 300w minimum so I would get a new PSU.

  6. Are you sure it would be a problem with the power supply? I am wondering if it's a problem with my motherboard being incompatible with my card. I don;t want to get anything else for nothing if it won't work. My card says it supports pci express 3.0. For my computer it says this for expansion slots:
    1 PCI Express x16
    3 PCI Express x1
    1 PCI Express Mini Card x1
  7. the GPU is reverse compatible... It is a PSU (Power Supply Unit) issue.

    If a system doesn't have a powerful enough PSU, does it perform badly or just avoid booting at all?
  9. Well... as you said in the thread opening: "Everything seems to be in place, but i get these short beeps when i boot up my computer, and my monitor powers up, but then it goes to sleep."

    That is what happens if the PSU catches it.... Otherwise it can get ugly. Get a 500Watt "80 x" rated PSU

    If you have not bought a new power supply yet, hang on. There are quite a few post on GTX 750 not being compatible or cannot boot up with HP PC. You may still have an under powered power supply but that may not be your only problem. See this HP support forum site: https://ssl.www8.hp.com/us/en/hp-search/search-results.html?ajaxpage=1#/page=1&/cat=Forums&/cc=us&/lang=en&/qt=%22GTX%20750%22%20graphics%20card%20upgrade

    There are people who upgraded their power supply but still face boot up problem.
