Hi, really need all your urgent help as I'm freaking out a bit as its not really my comp, and its fairly new.
Okay my computer turns ON, but makes less noise than it used to when working, and just shows a black screen...doesn't even enter bios.
Ok, I installed a new Graphics card, radeon hd 5450, installed the drivers etc, got it working perfectly. Then a short while after I also downloaded a reputable program called watt 2.2.5 to clear my windows non genuine message.
Then shortly after both, I was changing my theme, and the computer screen just went blank. Even keyboard wasn't working (I was pressing "caps" to see if caps light would come on and it didn't). So I powered off, now I just keep getting black screen! What has happened? How can I fix this? Really need your help! Thanks
