Hi im back.
My antivirus is Bitdefender, And i dont have an operationsystem DVD, it was built in when i bought the machine. Im trying to find out what version it is.
I started tonight to download and install the first link you gave me http://download.bleepingcomputer.com/sUBs/dds.com. i was pretty sure that the computer will restart itself afterwards. So i took some pictures so you know what happen. Its always the same. This is what happen:
First picture, Automatic Repair, shows everytime i start my comupter. Exacly the same happens if i press restore or cancel. So this time i pushed restore. The computer starts restoring and this take approximatley 10-15 minutes.
So, after 10-15 minutes of restoring i enter windows and it takes another 5 minutes before i can click on anything, just loading. when i finally can, i run the link (2nd picture) and it starts loading for about 2-3 minutes and my screen turns black and it restarts itself (3rd picture) HP logo turns up and the five small dots in 4th picture runs for 15 seconds and freeze.
Acctually, when this first happen, like 2 weeks ago, my computer started windows update and failed it because of this issue above.
I notice that both my firewall and antivirus was disabled and has been since this first appeard. If I try to start the firewall, you know what happens, it freezes.
