Did you mess around with the settings in your BIOS? If you did, make sure the boot settings are such that your computer tries to boot from your hard drive as the first or second option. It seems you might have changed the setting so your computer tries to boot from the network instead.

If that's not the issue, is your hard drive currently being recognized when the computer is started? What Realtek products do you have? I assumed the Realtek product is your Network Interface Card (the one that you connect an ethernet cable (one that looks like a phone cable except bigger) to, also called an NIC).

Make sure you didn't disconnect any cables that were previously connected when you installed the video card. Specifically check the IDE or SATA data cables that connect your hard drive to the motherboard, and the power cable that's connected to your hard drive.

Clicks when switched on, stops after a while, screen says reboot and select proper boot device or insert boot media in selected boot device and press a key

Your machine can't find the boot sector of the hard drive. This could be because there is a cd/dvd in the drive or the BIOS has the wrong boot sequence assigned.

At the startup menu i am getting a message that says, Reboot and Select Proper Boot Device or Insert Boot Media in selected Boot device."

Firt thing you can check is wthr your harddrive is detected or not. to do that you have to enter to the BIOS,To Enter BIOS you have to press DELET or F1 or F2 key(Mostly DELET). Now inside the BIOS in main menu check if your hard drive is showing or not. If it is showing there then you try to find out boot sequence, option after getting the boot sequence optuon check if the first device is other then hard drive.
if your harddrive is detected and your first boot device is also set to HARD drive then it might that your Operating system is Crash, in that case you need to re install the OS.
Now if you can see your hardrive in your BIOS then you can open the case( remember to unplug all the cable, Power, VGA, KEYboar ...etc) and try to inter change the harddrive cable connting cable, i mean just try to chage the port of the cable to other one and try switch on your computer ... if still you find the same problem then try changing new cable. ....well if still you have the same problem then i am afraid that you might need to replace the hard drive with new one.

Sorry for the Bad Englsih. Hope the above steps will work for you and you understood what i tried to say.

You might have another part that has gone bad. Check the RAM and see if it gives you any problems.

There is a program call mem test that you can burn to a CD and test your memory. But if your no longer able to get to the bios:
you def had a hardware problem.

I have put new hard drive in - When booted up it says - Reboot and select proper boot device or insert boot media in selected boot device and press a key.

there can be two scenarios
1. the harddrive is not installed properly
2. the harddrive is not selected as the first boot device in the BIOS of the computer.

After you install new harddrive, you will have to reinstall the Operating System in the computer as well.

Reboot and select proper boot device or insert boot media

its basically telling you that your master hard drive with O/S installation cannot be found in the booting system...Check if your master HD is not corrupted and see if your O/S still exist or maybe wiped out..

When I turn it on it says Reboot and select proper boot device or Insert boot media in selected boot device and press a key.

Please verify if you don;t have a floppy disk in your drive. If you don't then you have to verify in BIOS if is selected proper boot device - HDD.
If everything is set then you have problem with your hard disk, must check and install new operating system.

Computer beeping and saying reboot and select proper boot device

When you reboot, go to BIOS, restore factory BIOS settings. If that doesn't help, you'll need to reinstall your OS.

GeForce 8500 GT installation problrm

Try looking for a message in the BIOS startup screen usually delete or an "F(X)" something button i.e. F1 or F2 That says it will let you chose your boot device. If you can than press that and chose the hard disk option. If it doesnt let you or it doesn't work than theres probably something wrong with your hard drive and I doubt it has much to do with your video card unless the driver caused it. In that case try starting your computer in safe mode by pressing F8 after the BIOS startup and selecting safe mode and then uninstalling the driver from the change/remove applications part of the control panel. Of course if none of that works you could just yell and swear at HP until they help you. :)

good luck

Video card problem

Hi syaricky - First with your pc off, put your old card back in. Boot your pc and when Windows finds the card, just let it install whatever drivers it wants for the video card. It may ask you to choose the card or it may say it has found the most compatible driver for that card. That is ok. Then shut it down, and install your new card. When it boots and and says do you want it to install drivers say no. Then insert your cd and install. Once installed, go to your device manager and uninstall the old card. Start>right click my computer>properties>hardware>device manager>click on the + next to display adapters. Right click on your old video card and click on uninstall.
If this solves your problem PLEASE rate this as fixed.If not,DO NOT RATE YET. Let me know what happened. Just add a comment and I'll be happy to assist you further. Thanks. Let me know what happens.

Installed new graphics card and Windows won't start

If your new video card has a power connector, make sure it is connected to a power plug. If you already did that, it's possible your PC's power supply doesn't have enough power to run all your connected equipment.

To get your old card running, hit F8 repeatedly during boot-up until you get the boot options. Select VGA mode. It should boot up properly then.

Once booted into VGA mode, set your screen resolution to something simple like 1024x768 or 800x600, then reboot.

If that doesn't work, try hitting F5 repeatedly during boot-up to boot into Safe mode. You can then adjust your settings again there.
