I recently purchased an OCZ Tech Game X Stream 1010w PSU. After installation everything powers up, but the computer does not start going through the BIOS. All I get is a blank screen. After re installation of the old PSU (unknown model, came with an old Gateway tower) rated at 300w, I got the message of "Overclock/Overvoltage failure" and it told me to check my voltage settings.

I'm running an ASUS P5WD2 Premium board, with a Intel Pentium 4 CPU 3.40GHz and 1gig of DDR2 ram. I've heard in similar cases the issue has something to do with the settings in the BIOS.

So my question is, is this new PSU incompatible with my current setup or is it just a matter of tweaking the settings? If a tweak is needed I'd much appreciate guidance as to what the settings should be.

Thanks!

Building on the BIOS-level suggestions from and , focus next on isolating whether the problem is a BIOS/configuration symptom or a power-delivery issue from the new supply. The quickest way to narrow that down is to treat the motherboard and PSU as separate components and test each in a minimal, controlled way.

First, do a careful visual and seating check: verify the main motherboard power plug and the CPU auxiliary (4/8‑pin) connector are fully seated and latched, inspect for bent pins or loose wires, and avoid any adapter or cable swaps that might route the wrong voltage to the board. Remove nonessential devices (extra drives, add‑in cards) so only CPU, one stick of RAM and the board remain powered; that reduces variables and load while testing.

Second, verify the PSU rails. Use a commercial PSU tester or a digital multimeter to check +3.3V, +5V and +12V rails under an actual boot attempt and compare against ATX tolerances (reference: ATX power supply). Measure between ground (black) and the colored rails (orange +3.3V, red +5V, yellow +12V) and confirm the 5VSB and the power-good signal are present. If unsure about live-voltage work, get help from someone experienced—there are safety risks.

Finally, consider multi‑rail behavior and isolation steps: modern high‑wattage PSUs can have multiple 12V rails and OCP behavior that trips with particular loads; if the system only fails with the new unit attached, test with a known-good PSU or contact the PSU vendor for RMA. If hardware checks show the rails are within spec but firmware still reports voltage errors even after the BIOS-level steps suggested by and , pursue motherboard support or an update only after a successful POST to avoid bricking.

Try holding down spacebar when it boots. Also, go into the BIOS and choose to "load optimised defaults" then save - this is usually on the exit screen somewhere

Ok I'll try it and see what happens. I assume this will work even though it doesn't even get to the bios?

yeah spacebar (usually) resets all overclocking settings

If the spacebar doesn't work, clear CMOS.

yeah, do that using either the jumper or by removing the battery
