Hi, I recently went to turn on my computer, and it loaded the Dell logo and then simply had a blank screen. I restarted it a few times, and tried taking out the battery and replacing it, as well as restarting while charging. None of that worked, so I ran diagnostics and the only thing it's telling me is that the hard drive is not detected. It says Hard Drive 0 instead of what it should say, which is Hard Drive C, I believe. Also, I did some testing on the memory, and now there is just a red x by the memory instead of a green check mark, like most of the other items have.
My computer is a Dell Inspiron, running on Windows 7.

If you have 1 hard drive...it is hd0. 0 being the first number in computer terms. hd 1, would be a 2nd hard drive. So, that part seems right. How many ram modules are in this computer? If there more than 1, take them all out except one and then see if the computer boots, if not, take out that stick (powered off) and put in one of the other sticks, and try and to boot up the computer. See what that does for you.
Try this, go to the BIOS setup, & change the disk controller setting from AHCI to IDE.
HopperRox is correct. It appears your hard drive is being detected. The primary partition on the first hard drive is labeled by Windows as C:.
Okay, sorry about that. I am not very clever when it comes to fixing computers, although I try, so I didn't realize it was supposed to say 0. I tried JohnW's solution and now it's working! I have no idea if the other solution would have worked or not, since I did not need to try it. Thanks so much! I really appreciate the help.
