Hi everyone, I'm having a really frustrating time making my new computer work properly.

Basically, my computer will randomly freeze when it starts. Because of this, I can't install Windows, run memtest or even sometimes boot (i need to keep rebooting until it finally does the CD boot).

To be more specific: when I start memtest86 (single processor mode), it'll run for about 10 seconds and then reboot the system on its own. When i boot from the windows 7 install dvd, it'll say "expanding files", but then freeze anywhere from 0% to 95% consistently every time. Finally, sometimes when i boot my computer, it'll freeze on the Memory Test step on POST.

My Setup:
RAM: 2 x Kingston HyperX KHX6400D2K2/4G
CPU: Intel Q9650 (quad core 3GHz)
Motherboard: NForce 750i SLI
Video Card: GeForce 9800 GT

I don't think the computer's overheating. I've left it in BIOS' temperature page and the CPU temp never goes above 70 degrees.

I've tried swapping my two RAM sticks and running with only one or the other, though that doesn't change anything. I've updated to the latest BIOS on the motherboard's website.

When I boot the computer, it'll say that the memory is at 667MHz instead of the 800MHz that's written on the RAM's specs. Could this be the problem? The timings on the boot screen say 5-5-5-15 (so i think it's right).

Does anyone have any idea?

Thank you!

Hello. I have done Default Settings on the BIOS screen multiple times without luck.
 
your RAM might need a little more juice, try raising the RAM voltage a bit
 
Something ain't right...
What's your PSU?
Tried manually setting voltages for your RAM/CPU?
Tried underclocking the CPU?
Tried using onboard graphics and leaving the card out?
 
Oh, I have never done timings/voltage before. Do you really think this is the problem?

Some quick updates as to more symptoms:
- I started the computer and it stayed at a black screen. Looking on the motherboard, the LED screen says 02.
- I hit the reboot button and then the computer started booting, but it's now frozen on "Main Processor : Inten(R) Core(TM)2 Quad 3.00(333x9.0)".

One other quick note: At one point, a couple days ago, i mis-mounted the CPU fan and the Overheat light came on. Do think there was any damage because of this.

mmm I doubt it. What PSU are you using? Because it certainly could be a PSU issue.
 
I had this happen to me with a P35 board and an Antec Neo HE 550. Couldn't make it through an entire installation. Would just randomely shut off.

Switched out the psu and it never happened again. Used the psu in a different system and never had a problem with that system. How a psu and a particular system can be incompatible I will never know........even if you explain it to me. lol :D

*shrugs*

I also liked the suggestion of giving the ram a little extra juice.

I would lay bets it is either the ram or the psu.


Also.......isn't 70C too hot for a Penryn Quad??
 
I just tried setting the voltage to 2.2 volts from 1.8. I also tried forcing the clock speed on the memory to 800mhz. Memtest86 is still crashing at the exact same spot every time.

The psu is a ocz 700w (modxstream-pro).
 
The led screen is on the motherboard I guess for troubleshooting bootup issues.
 
Don't overvolt it too much. Try this: underclock your CPU/RAM and boot.

Probably a good idea to see what it means. Check the manual or online or something.

EDIT: If booting with underclocked CPU/RAM doesn't work(UC down to 2ghz or something, not too low) try taking everything out of the computer case, putting the motherboard on a cardboard box, then booting.
 
Take another brand of ram and boot the computer and then swap back the hyperx and then set the voltage to 2.0v

Sound strange but that is how I fixed the problem with mine.
