My p42.0 reboots itself, help!!

[gokur008]

I have a p4 2.0a running at 2.8ghz 560mhz bus, and it runs fine most of the time at 39c idle, but once in a while loading something performance intensive my machine would just reboot itself. I was wondering if maybe its because my voltage may be too low, I?m running it at 1.55v is that enough or should i bump it up more. Please help.

Thx.

here are some detailed specks of my rig

Up the voltage a bit. Appears to be not stable. You ran prime95 on it to check for stablity?

i can upp the voltage but i wanna know wuts the stock voltage for teh 2.8 p4 i dont wanan do too much on it, wanna keep it cool '
I have ran sandra burn in wizard seemed fine, but i did low level and only for 20 min

Bring the voltage up one 'notch' and try that. keep going until stability is reached. Also, have you checked the voltage from your powersupply? That was the source of my random reboots.

Thx, it seems to be helping. And i do have some generic 300watt psu, i might replace that with an enermax or an antec 400watt psu
