Hey guys just OC'd my sempron 3100 to 2.25ghz up from 1.8ghz, is it safe to go higher?

this is what i based my overclock on

CPU freq = 250MHz
CPU multi = 9x
HTT multi = 4x
RAM freq = 166MHz (DDR333)
PCI-E = 100MHz
PCI = 33MHz
Spread Spectrum = disabled
Cool'n Quiet = disabled
RAM voltage = add 0.10v to default voltage
CPU voltage = oncrease as necessary to stabilize

CPU at 2.25GHz with RAM at 208MHz. HTT bus at 1000MHz

ok guys the above overclock is stable, i just however, inserted an older pci e graphics card compatible with system, it recognises it fine and works, however when my pc logs on after boot my keyboard and mouse (USB) don't work at all, not recognised it seems, at first i thought it was power, or the lack of it, so i replaced the stock 300watt with an OCZ 750watt psu and tried again, still the same, any idea why my usb devices arent active?
