Black screen w/ Blinking underscore

[Redthumb]

Hi, Guys My little brother did something to his computer and I'm stumped on what to do. The windows logo starts up and after that there is a black screen with an underscore blinking.

When starting the computer the only F buttons that work are F12 and del( opens boot menu) Button.



Windows 7, At the black screen with the underscore I can hear the beeps of the keyboard presses.



. Troubleshooting so far

1. Made sure the boot was set at default and the hard drive was selected.


2. Alt+F10 did bring up the recovery program with two options restoring all setting and backing up files and deleting everything and re-installing everything to factory. I tried Both and the problem continued.

3. Nothing is in the Cd-Drive and no external drive.

4. I think it must be a hardware failure but ive never gone this far. So some steps would be nice to help me figure this out. I have everything I need to open the computer just never done it before.

i think either windows is corrupt or there is some problem in RAM..
when windows boot it loads important file from hard disk to RAM.. BTW "ur link doesnot work"

and try out other ram from your friends or other working s/m

Windows isn't corrupt;
85% chances are that the RAM is making the problem.
15% chances are that it's the HDD or some other part is making the problem.
Try to open the computer, just check whether every parts, (like ram, cables, SATA cables, HDD, etc.) are connected properly.

did you try different ram??or "opening in safe mode" try out these two things
if ram doesnt solve your problem,
then you have to reinstall windows,as some files might have gone corrupt or missing..

Ive tested the ram with memtest and there are no errors i dont have any different ram to try it out with. HOw would i go about reinnstalling windows?

then thats the only choice you have left with..
use bootable windows cd/dvd or bootable windows USB to reinstall your windows on c:
dont install it anywhere else..
remember doing this will wipe out any data stored in the c: drive but your other drive's data will remain intact..
to make bootable USB

make your USB pendrive bootable / make ISO from cd / dvd

no u dont need any installer..windows 7 in your USB will do that.
do these things

plug in your USB

go to bios>booting order /sequence>move usb hdd on the top >save and exit..
it will start booting from USB and just follow the instuctions thereafter..
