my mobo's slot is a PCI-E x16 but i don't know that there's a 2.1 slot.
i searched through the internet and my current GPU (9500gt) was a PCI-E 2.0. but i don't know if this was an issue:
1. before i overclocked and changed its fan, my game (Prototype) crashed while playing for about 2-3 hours still i managed to fix it by shutting down my pc for about 30mins and cleaning its fan.
2. i experienced that "crashing" issue again like a week ago when NFS Shift froze in the middle of the race. that time, my 9500gt was overclocked with a new fan so i backed off the clocks and restarted my pc. so far, everything is working well right now.
is Inno3D GT430 a PCI-E 2.1 card? coz i've searched on the net and it says that it was a PCI-E 2.0 card. ima go check at my mobo's box at home if my GPU slot is 2.0. btw, thanks!
