Quote:That is all because of "junkyard components"! It reminds me of a web-browsing rig that I've built for my parents not so long ago from budget components: Core2Duo E4500 that I got for free from a friend, DFI Blood Iron P45-T2RS motherboard, Patriot DDR2 RAM, Nvidia GTS450 and Chieftec 500W PSU that I had laying around. The amount of troubles I went through to get the damn thing to work exceeded my worst expectations: not POSTing after shutdown, BSOD's, HDD not being detected, just to name a few. Now I know that nearly all of them were caused by the motherboard (I'm never buying DFI product again by the way), so it taught me to never save money on it, its better to pay slightly more for the base of the system and not pull your hair out later on.
Anyways, I assume you are currently using P5B-SE with X5460? Or some other motherboard / CPU? If CPU/RAM is at stock settings. Are you using Intel BOX cooling or EVO 212 Plus? The restarts might be caused by:
- Unstable CPU (if that's the case, restart is usually preceded by a few second freeze of the screen/sound (buzzing noise)/BSOD)
- CPU temperature reaching Tjmax (might happen with X5460+stock intel cooling)
- PSU overload protection (highly unlikely with your current configuration, but just to be sure, you might want to measure how much power is your system consuming under heavy load)
- HDD bad-sectors (use software like HDTune to test your disk for errors, unless you've already done that)
- Memory errors-caused either by wrong settings, or damaged memory module
To rule out the first 2 causes, run Prime95 in SmallFFT mode for at least 2 hours and make sure there are no error's / CPU temperature stay within safe margins. In order to rule out the memory, run memtest86+ for at least 2 hours.
