120 W amp effects change

I have a 120 watt spider IV when I turn up the volume and start playing the effects change at random.

Since you mention this happens when you turn up the volume, the likely reason is that vibration is causing one or more of the FX control knobs to 'wake up', which would change that FX to whatever it is pointing to at the time.
One way past this is to 'park' the controls at '0' (counterclockwise all the way), then select the preset sound you want. If this happens when in manual mode, you can save the tone you have adjusted to to a user preset, then park the knobs at 0, then select this new preset.
Someone also suggested putting a small Oring under the knob so it does not turn as easily.
The information above may not be current, and you should direct questions to the current forum or review the manual.
