I have HP pavillion a6430f pc desk top and when I turn it on it says Windows not found. how can I fix this?

You didn't say what operating system you were using, but here is a link to the instructions for Windows 7 on an H/P:

It's the slot in which a video card plugs in, if you want much better video capabilities than what the onboard video can deliver.

go to control Panel and look in the Display settings, you should be able to see your video card in number one monitor as well as in number 2. I hope this helped. Good luck and have a pleasant day!!!

I checked: http://support.hp.com

The manufacturer's web-site:

http://h10025.www1.hp.com/ewfrf/wc/product?product=295748&lc=en&cc=ca&dlc=en&lang=en&cc=ca

lists the 'HP 1010 FAX' product, but not a "LaserJet" 1010.

Or, see Microsoft's web-site:

http://www.microsoft.com/windows/compatibility/Windows-7/en-us/Details.aspx?type=Hardware&p=HP%20LaserJet%201010%20Laser%20Printer&v=HP&uid=Q2460A%23ABU&pf=0&pi=9&c=Printers%20%26%20Scanners&sc=Laser%20Printers&os=32-bit

which states that the 1010 is *NOT* compatible with Windows 7.

the first thing to do is to check the power cable, try using a different one, if its okay listen to hear if the cooling system(fan) is spinning, if not then its very likely to be your powerpac

Hold the power button in on the computer for 5 seconds. Wait another 5 seconds. Now hit the power button as you normally would to turn the PC on. It should boot normally.

does the messages affect the operation of the computer? is there internet hooked up to that computer? if so have you been doing all the updates that are available for the computer this includes the optional updates? the other thing you can try is contact windows tech support and they can help you out also. i found a solution for windows host process you can go to this web site:http://support.microsoft.com/kb/953916/en-us?sd=gn
copy and paste it at the top of your screen. and so far there is on cure for the hp advisor not working. i checked all over the windows website and they have got a cure yet. hope this helps you, let me know.

which version of IE you have now?

It may be that the brightness of your monitor is turned all the way down. In the lower left of your keyboard, there is a "FN" key between the windows logo key and the left ctrl key. Hold this fn key down and continually press F8 until the screen brightens up.

Hopefully this helps, keep us posted!
