I need to re install OS for a HP a510n desktop but cant find drivers and dont know which ones.

Do you mean the HP Envy 120 e-All-in-One printer? The drivers and full software for the printer are available from the HP support site: http://h10025.www1.hp.com/ewfrf/wc/softwareCategory?cc=us&dlc=en&lang=en&lc=en&product=5203211& . Select your OS and click Next. To download the software, expand the Driver - Product Installation Software. For best results get the Full Software package instead of the Basic driver. To order a replacement installation disc, expand the section labeled Order Physical Media.

If you need the drivers for the HP Omni 120-2135a, go to http://h20000.www2.hp.com/bizsupport/TechSupport/DriverDownload.jsp?prodNameId=5256682&lang=en&cc=us&taskId=135&prodTypeId=12454&prodSeriesId=5186995 . Click on the link for your OS. There should be an HP (update advisor) utility on your computer that will check the HP site for updated drivers. This will be on the computer as long as you do not do a clean install of the OS. (Win8 Restore will erase the desktop programs. Use the restore partition to return to the out-of-factory configuration.)

I hope this helps.

yes the 2 computers are different. Different processors, different memory,different graphics card.To get your ide drive from your hp pavilion a510n to work in your hp pavilion a1330n, you will have to completely re-load the drive when it is installed in the hp pavilion 1330n. Then it will work fine, but you will not be able to use that drive in your hp pavilion a510n. because you will have the same problem but in reverse.

For that you need to install your camera inbuilt in driver.

HAVE YOU CHECKED HERE. Hp provides a hgh definition driver for your OS.

First you need to know your OS. Even on the older versions of Windows, the Control Panel should give you your OS version in the System panel. If you have 2000, XP, or a newer OS, you can get the drivers from the following URL: http://h10025.www1.hp.com/ewfrf/wc/softwareCategory?lc=en&dlc=en&cc=us&product=82029&os=228&lang=en&

If you have Windows 95, 98 or ME, HP doesn't have the drivers for those operating systems.

I hope this helps. Since the software must be installed before you attach the USB cord to the computer, you may need to uninstall any drivers that attempted to load on your first attempt. Look in the device manager (in the Control Panel again) for any devices with an exclamation point next to them.

Fallow this link and download The HP full solution software driver. This driver is for Win XP. If you have another OS go back a few time and change the selection for your OS.

Do not connect your printer to your PC. Install the driver and sometime in the installation it will tell you to connect your printer to your PC.

Let me know...
