I have a prebuilt HP media center PC. It is no longer factory original however.
Recently my original hard drive went into failure (a pattern I have seen. I only buy HP computers and within 3 years the original hard drives always fail). I did a little research since this is my third failed factory hard drive in an HP computer, and learned that they are built with the minimum possible PSU to power ONLY the factory parts. I had added a graphics card, and it was suggested to me the inadequate power had damaged my drive over time. This lead me to a few upgrades.
So at this point I have upgraded from a 300w PSU to a 500w PSU. It has been installed and tested and works perfect. With the new PSU, suddenly the hard drive fired up again but it was short lived and went back into failure. While it was operational though, I added 2gb of RAM... You know, cause you can never have enough RAM. lol
So when the drive went back into failure, I caved and replaced the drive. I was a smart cookie and remembered to remove the graphics card (an upgrade from literally the day I bought the computer) since it was not an original part, but forgot to remove the seemingly harmless stick of RAM.
I started the process of installing the new OS, and everything went smoothly until the "expanding files" phase. It was stuck at 0%. I gave it a good 2 hours to work itself out, but I knew it was a lost cause. I no longer heard any drives spinning. So I pondered, and remembered the RAM. I shut it down, disconnected, and removed the RAM. I also reset the BIOS to factory while I was at it to make sure everything read properly from the BIOS when I tried again. Musta knocked my optic drives cable loose cause at first it was missing, but a reattachment and it was okay again.
So now I boot up again. Another mistake I forget to boot from the optic drive. D'oh! it tells me the hard drive is in failure, I assume it is from the incomplete OS on the drive. I reboot, this time REMEMBER to boot from optic and now... it says "bootmgr is missing" *head desk* tried twice now. Losing hope. Help please, I know I have done something else wrong I am missing.
Thanks in advance (please don't laugh at me :-P)
