300watts is meaningless, you need the ACTUAL output or TCW of the 3.3v and 5v lines
Many 300watt psus are rated MAX which basically means the PSU ISN"T 300watts at all but can surg to that amount briefly.
But the PSU may have NOTHING to do with the lockups, many times a poor motherboard, failing video card, improperly attached heatsync, or a bad HD can all cause lockups.
Good Luck
