I have read the sticky's but it did not help my problem so here goes.
okay, so i will start from the beginning. I have a fairly old computer and I bought a graphics card for it (ati hd4730 to be exact). I did not know that this video card needs to be connected to a 6pin PCI-E, so i bought a molex 4pin to 6pin adapter. there's 1 6pin end and 2 4pin ends.
I plugged both the 4pins and turned on my machine but nothing appeared but a black screen (i knew it was connected because it did not say no signal) and my hard drive did not sound like it was spinning. I forgot to mention that i have a 500W PSU. When i unplug the 4 pins from the adapter, my hard drive would start up and if i was lucky and reconnected it, my windows would start with the monitor connected to the graphics card but it would freeze and if i restarted the computer it would restart then go back to the black screen.
I was messing around with the power cables while the computer was still on and i think i short circuited my hard drive because my windows would not start up anymore even with the Onboard Graphics connected to my monitor, please help me. I have 2 problems but right now i want to know if i can fix my hard drive cuz i had some important things in it. thanks.
