Sounds like either your new drive really is bad or you've got a
setting issue in your bios. By your description it sounds like your
bios is seeing a problem in POST when your booting your system. If
you press f1 will it continue to boot up as it did before? Does it
cycle back and repeat the same message? Does the windows splash
screen ever appear?
Open up your bios and make sure that the settings are all ok. There
are several brands and models of bios each having a different key to
hold down as the PC boots up. If your not sure how to do it, you may
want to get a more knowledgable friend or certified technician to help
you with this part.
You may want to recheck your connections on the new hard drive. Is it
a SATA or IDE drive? IDE drives require jumpers to be configured on
the back of each drive. They should also be connected to the IDE
cable a certain way (master drive on the end connector of the IDE
cable, slave drive on the middle connector) If these things arent
configured correctly it may not work. If your using SATA drives then
disregard this paragraph.
SATA drives are pretty simple in their connections. One drive per
SATA port on the motherboard. Make sure the cable is connected
securely, try using another SATA port on the motherboard or maybe
another cable.
