Random Reboot issues

[wip3out]

hey guys...

My problem is the following.

I recently built a new pc.
I've installed Windows 7 RC. 2 days later a reboot happened but I didnt pay attention. For the next days all worked great. 1 week later one more reboot and the same for the next week.
Since then its been 2 weeks.
So, last friday my internet connection started working. The first thing I did was to update all of my drivers and install all windows updates.
Since that time I had almost 15 reboots!!!! all without bsod and all during these two days.
I tried to rollback the drivers but that didnt help.
Also I've run memtest86+ for about 10 hours and it found no errors.

The reboots can happen at any time.

my specs are the following...

Intel Core 2 Quad Q8300
Asus P5P43TD Pro
2X Trancend JM1333KLU-2G DDR3
Nvidia GeForce GTS 250
Enermax EPR525AWT PRO82 PSU (525W)

I have read in many places that DDR 3 require more than 1.5 volt to be stable so I tried raising it to 1.7 and now I think that it isnt happening that often but when I tried playing a game, the first time there was a freezing after about an hour and the second after about 20 minutes.

Overheating is not the problem (at least for the cpu) because I have tested it.
The next thing I'm going to do is try working with only one of the two Dimm of Ram and see how this is going.
I've also considered the possibility of faulty PSU but if I'm correct I should be having that many reboots from the start.




here is the event details after the last freezing.

I'm really confused so any help would be very much appreciated.

First of all, if you just built your PC, the last thing you should do is OC it. Let it 'seat' for a while, give your tim (Arctic Silver) a chance to bond. They recommend 200 hours of use before it gets a good, solid contact between the heat sync and the chip.

For now, run with defaults on your BIOS.

And FYI, fill out your system specs in the lower right, before a thousand other people ask you to.

 

[wip3out]

my intention wasnt to OC the computer. No way. I like its performance as it is.

The reason why I've added the extra volts on the ram was to make it more stable if possible.



A lot of people had issues with ddr3 1.5 v so I supposed I should give it a shot.

about my specs, they are included in my first post and I've added them to my profile as well.

 

[Captain Zero]

~1.9v for DDR3 RAM is pretty standard. If your BIOS is defaulting to 1.5v you might consider a BIOS upgrade.

And yes, specs in the bio is good.

 

[wip3out]

my bios was set to Auto. And I believe this means that it was sending 1.5 since thats the default value for the specific ram.

that being said, could the Auto setting be the problem for the instability of the computer?

wip3out could you go into c:\windows\minidump, zip the dump file (*.dmp) and upload it to us to look out? If there isnt anything in minidump you can always search on *.dmp

It seems that the minidump folder doesnt exist.
I've found 3 .dmp files in the following folder C:\Windows\LiveKernelReports\WATCHDOG

should I upload one of this instead?

Before you do minidump may be hidden. If you show all files/folders and minidump is still empty upload the ones from watchdog

I've attached the zip which contains the three dmp files I found.

But none of these seems to have been created during the recent reboots.

:S

No minidump folder.

1.5 since thats the default value for the specific ram

Where are you getting this 1.5v figure from? Is that the recommended voltage listed on your RAM?

 

[wip3out]

Ram's specs included that it can work with 1.5 v

 

[Captain Zero]

Ok, can but may not. Looking at your specs, I'd suggest trying ~1.95v for the ram and enabling extended boot options to run the ram test at post.

/disclaimer - If you blow your rig, it's not my fault.

 

[wip3out]

for the last 15 hours the pc is running without reboot.
1.71 v is the ram voltage.

but, I havent tried any games.
