Hello guys.
Just wanna share some of my experiences here.

My motherboard, Biostar TForce 570U got 3 slots of PCI.
I never use the bottom one since that is the place for my UV CCFL switch.
I placed my soundcard (Creative SoundBlaster 5.1) at the 3rd slot from the bottom.

Unfortunately, my PC cannot detect the soundcard anymore AFTER I overclocked my PC on the last 3~4 months.

So I changed the soundcard to the 2nd slot from the bottom.
Everything went fine, until yesterday, my PC cannot detect it again AFTER I overclocked my rig to 2.7GHz.

I did try to un-install and re-install it back, took it out and placed it back, but nothing happened. The system refused to detect my soundcard.

So I would like to know, is this consequences of overclocking ?
And why did this thing happened ? I didn't touch any of PCI part during overclocking.
Hope you guys can help me solve this problem.

Thanks.

sorry for the late reply..

for the first damage, that time i didnt update my bios yet, and there was no option for pci clock in BIOS..

after i updated the bios, there is an option, and it default clocked at 100MHz..
and to be honest, during overclocking, i never touched it..
the 2nd damaged happened after the bios was updated..

so since i never touched anything regarding pci clock during overclocking, i never expect this thing would have happened..
