Question Is my mobo damaged?

[Maq___]

Hello,

I added a case cooling fan to my fanless GPU, it is a 3-pin fan connected to the AsRock P45DE3 chassis fan head,and since then my PC became very slow and unresponsive ,I even can't install the Win OS.

I removed the fan and unplugged it,but the PC is still too slow and unresponsive.

Is there a possibilty I have damaged some hardware component,maybe the mobo?
One screw fell on the mobo when I was mounting the GPU on the mobo.

Please help me

Load Default settings in bios... or reset bios (remove your CMOS battery for 5+ minutes).

I've just tried it,but it didn't work.

Is there any way that you might've unplugged partially or move you SATA Cable from the HDD or you Motherboard?
Reinsert them to make sure...

It is doubtful that a attached fan could damage your motherboard.
It is doubtful that dropping a screw on the motherboard would have caused damage.
(I assume the pc was powered off and that the screw was removed)
What was the make/model of the fan?
If it was a very high amperage fan, then yes you could have overloaded the capability of the motherboard fan header. It is hard to imagine this excepting for a very high powered fan.
