One of my nephew's PC was giving artifacts on screen and freezes, sometimes not showing anything at all on the monitor even during boot. So I figured that his graphics card was faulty. His system spec:
7300GS graphics
Asus P5LD2-SE motherboard
400W Power supply
Now, his brother had a working PC with system spec:
8800GT graphics
Asus P5N32-e SLI motherboard
550W Power supply
So I took out his 8800GT card to test if it would work in the faulty PC. I installed it into the PCI express slot but there was no 6-pin power cable coming from the power supply. I decided to try my luck and see if it would show any picture on the screen without the additional power cable to the graphics card. When I turned the PC button on, I heard a loud beep sound which I think was coming from the graphics card. There was no picture on the monitor, so I turned the PC off.
Now here's the worse bit. I put the original 8800GT back into the working PC and forgot to plug in the 6-pin power cable and switch the PC on. I heard the same loud beep noise. I turned the PC off and connected the 6-pin power cable to the graphics card and turned the PC on, but PC was DEAD!!!
I can only see the green light on the motherboard, which turns off after about 20 seconds by itself.
I have removed every component other than the motherboard, cpu and ram, power supply but fans do not spin. I have swapped and used different ram. But the problem is same... the motherboard LED does light up and then turns off after 20 seconds. Non of the fans on the system spin. I see no picture on monitor. Nothing is working.
I have tested the power supply in the other PC and its not faulty.
Please help me bringing the 'good' PC back to life. I know the first bad PC needs a new graphics card, but what happened to the second PC t hat was working before swapping graphics???
