Stomped on this random reset

[vto]

I just finished configure a new mobo/cpu, but I'm having weird random reboots. Here are my specs

Mobo: Asrock 775Dual-VSTA
Cpu: E6600
Ram: 2 x 1GB Cosair Valueselect DDR2-667
1 x Seagate 300Gb
1 x WD 80GB (Main Drive)
1 x Pioneer DVDRW
PSU: Enermax 300Watts

I've been running some burn in test to see if it was the cpu overheating. But it doesn't seem to be the case. I have stress program running at the same time (because 1 program will not max out both core) and the program also test out the physical memory as well.
Got both cpu to max out for around 30 mins and available physical memory to minial, but still could not duplicate the reboot

These reboots are just random reboots, no BSOD or warning messages

So I am suspecting it could be a power issue? but when it's under such heavy load the voltage seems stable. It can't be an overheating issue since the max temp been around 47C.

So I don't know what to troubleshoot this one...

1 more note to add is that I've been having weird IDE issue with this motherboard, as sometimes when I do a manual restart from windows. After it completely quit out of windows and getting ready to POST. The system would go completely dead, the system is still on. However, no screen, response... In order to fix his, I have to open the case up and unplug the cable connected to IDE1, then reconnect to it.
I searched on this forum around and it seems like it may be a board issue or something is not grounded properly ?

Anybody have a clue ???

You didn't tell us what your vid card is, but at 300 watts, your power supply may be a bit weak for your system. If it's marginal, that could easily cause random reboots.

If you have access to another supply, you could test it without having to disassemble more of your system.

Hope that helps.

oh sorry,

the vid card is ATI x800xl

onboard lan and sound

My first thought as well.

Are you overclocking at all?

 

[vto]

No overclocking

Cpu/and ram is brand new
mobo is an opened box

and the rest of the componets are from the old machine (vid card/harddrive/psu)

Old machine was a A64-3000 with 5 x 512 and same vidcard and hd

And an older machine that used the same PSU was a A1.4, and I once had the PSU support 5 IDE hd's, 2 pci nic, ti-4200...

so now thinking back, could this new cpu use as more power than 5xIDE hd ?

Your PSU should be powerful enough. Might still be it, but the prime suspect is the RAM. Memtest is not 100% reliable. Try using only 1 stick and see if that helps.

why do you say it may be the ram? could you please explain ?

Because I've ran the ram down to almost 0 available, so doesn't that eliminate the idea of a bad ram ?

My honest to god first thought was a bad/underpowered PSU, try something with some more watts, or at least some stronger rails. 350+ (id try for 400) from enermax, Antec, Sparkle should do you.

update... it is the PSU... new psu and solid system
