Windows 7 - Random Reboot problem

hey guys...

firstly, congrats on making this site a very helpful place.


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.

Sounds like you are doing the right thing.
Check the temperature of the video card.

Have you tried setting it not to automatically restart after system failures? I can't remember off hand if it's different in Win7 but in XP it used to be under Start>right click My Computer>Properties>Advanced tab>Startup and recovery Settings>uncheck "Automatically restart" under "System Failure". Maybe it's BSOD'ing but it restarts too fast to see it? let us know how your testing goes...

I have tried that. still no bsod.

I'm running the system now for about 10 hours with the ram working with 1.71 v and till now no reboot.

I'll try playing a game to see if it will crash or not.

I'm having the same problem with a copy of Win7 Pro. The copy is not beta or RC, but educational, therefore "paid for".

I have turned of restart on BSOD, she still reboots.

I didn't have any problems after first install.

After one or two windows updates, the video blinks in and out and the wmp300n wireless doesnt work.

I've tried everything, cant figure it out!

Edit: just noticed that only the Hauppauge WinTV card shows up under Video Cards in the device manager. That card doesn't ouptut to the tv, a regular nvidia card does - what is that about?
