I just finished building my computer, I am using a gigabyte motherboard and I have already installed windows. After i add some different hardware components, I need to restart the computer, this is where I can't come back. The first time in Bios, it finds the hard drive, it has all the details of it. When i restart it, the same info is still there, but when i refresh it, it is blank as if it can't find it. The main problem I have is when I start up the comp. , it gets to a certain point to where it says Boot from CD , it won't go any further unless I put the windows cd in, and from there, I can only re-install. So I have changed the Boot sequence in the BIOS, to HDD.0 , HDD.1 , HDD.2 just to make sure it wouldn't say anything about the cd, and it would hopefully boot from the hard drive. It still says the same thing, like it doesn't recognize the hard drive. Any ideas ????

Take out the CMOS battery for a few hours, then put it back in and start your computer.It should say something like "loading setup defaults". You may have to go back in and set the clock. Hope this helps.

Congrats on your new computer! Sounds like you specified to boot from the ROM, I'm not sure how that happened. Seems like if you edit your boot.ini file to boot from the HD it should work fine. Control Panel\System\Startup & Recovery, Settings\System\Advanced\Startup\Edit. (long as you are in there, set your dump to Small Memory Dump-saves huge amount of space & time if XP dumps after a crash) My normal XP Boot.ini, boot from the Harddrive, is: [Boot Loader] Timeout=5 Default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS [Operating Systems] multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /fastdetect Check yours; it probably now references the CDROM.

Actually, Dick above has a good suggestion, why don't you try that first? In fact, all you have to do is power down, pop the battery for 60 seconds, and there should be a tiny jumper near the BIOS battery that is used to erase all BIOS setting as reset back to default. Whole thing should take about 2 minutes max.
