Randon Shut downs, does this sound like PSU

[jkaero]

Ok, i bumped the core up to 1.85 from 1.825 on my t-bird 1.33 and now I seem to be getting random restarts, i wouldnt think this little voltage change would make that much diff, but I dont know. Also, after it shuts down, if I look at the mb a green light is still on, on the board, if i unplug my psu after a couple mins it goes out but the comp still doesnt start rite up, I have to unplug the power cable to the mb, after I plug it back in it starts rite up. Here is my sys:
Asus A7A266
T-bird 1.33 o/c to 1533 768megs pc133
2 plextor scsi drives (with adaptec card)
40gig maxtor ide hd
sb live
Elsa Geforce2 gts
Netgear NIC
300watt powersupply

Would this be the PSU, or anyone have any ideas

Sounds like a power supply problem. If you go back to 1.825 do you still get spontaneous reboots? What happens when you run it at 1.85 at the default clock speed. Is your psu AMD approved?

What do your temps look like? What kind of hsf do you have?
That could possibly be what is causing it if the psu is good.
