Is this a memory problem? or CPU problem?
Hi, I've had this issue for some time, and have never really figured out 100% what is causing the problems...
I have run several tests to troubleshoot the problem, but still am not 100% sure what the problem is.

The problem happens while playing a game, or sometimes while playing a movie.

Basically, at random, while doing either of the above, the computer freezes (stops completely), cannot "ctrl+alt+delete" "altF4" or anything, the computer completely stops with everything on the screen paused, including the mouse.
This forces me to have to restart the computer.


So heres what I have done to trouble shoot:
I tested new ram in the motherboard, and found that one of the slots are faulty on the motherboard (if ram is inserted in it, computer fails to post).

I uninstalled the graphics drivers, downloaded fresh drivers, and installed them.

I downloaded fresh copy of direct x, and installed it again.

I ran "memtest" on both my memory cards, and they both passed.

I re-installed windows, and still had the problem.
This version of windows CD Installer, has the latest direct X built into it.



I have found that I can stop the problem while playing a video, by finding the process in "task manager", and turning affinity to using only 1 core.

So what could be the actual issue here?
A memory card problem? even tho I have bought brand new cards?
A motherboard problem in the slots?
Or a CPU problem?

You know one problem - DIMM slot... Did you try other sticks in the same slot, with no sticks in the other slots?

What shows in BIOS for ram with only 1 stick in the bad slot? Same result with other sticks in the same slot?

Is the BIOS configured for Dual channel for both channels? Or only the channel with the bad slot?

nah it should not be a power supply issue...
I just bought a brand new $150 power supply.

and yes it does the same thing with any ram chip in that first slot (first slot meaning the furthest to the left).
Putting one chip (any chip) in the bad slot by itself, causes the computer to not post at all (no bios appears at all).

Did you look in BIOS for single vs. dual channel ram settings?

First of all, you need to post your exact system specs; ie make and model of mb, exact cpu, brand and speed of ram, brand and wattage of pw supply, etc, etc, etc. Post links to your parts if possible.

Thanks for the replies. I will check the bios settings again now, but from memory, I think it was set up for duel channel.

As for the specs, here they are:

CPU: Intel i7 860, 2.8ghz
RAM: one 2gb stick, and one 1gb stick, both DDR3, and probably Crossair.
Motherboard: Gigabyte, GA-P55-UD3 (not all that great, but it fits the needs).
Graphics card: (ASUS), Radeon 5670 1gb GDDR5
Operating system: XP Professional
Hard drive: 1 IDE 120gb hard drive, and one 500gb external(usb) hard drive.
My Sata harddrive died recently, its been a long time coming!

As for the power supply, I cannot see any specs on the side like usually displayed, so I'm guessing its all on the top of the power supply(in between the top, and the roof of the case).
It was supposed to be one of the best out at the moment...
sorry I cant remember the brand or watts

Hey dude I'm having a similar problem (the freezing), the first time round a selective startup worked for me. Second time (now) not so much.
