Cant narrow this problem down

So, I have a computer Im trying to diagnose. Ive tested the HDD - its fine. The PSU seems fine. Motherboard seems fine and audio visual seems fine but when I do a memory test the computer shuts down. Now either the CPU is overheating and the computer is cutting off or the RAM is THAT bad. Im not sure what it is. Before the computer was getting a 0x0000004E blue screen error so I nuked the hardrive and tested whether or not it was bad and the whole test went by with no errors.

The only time the computer reacts is when the memtest is going. I ran the computer for hours when I first nuked the drive and no shutdowns or restarts occured so what do you think is the problem?

Have you tried Memtest x86 yet or are you using the built in memory test in Windows? I suggest you run Memtest x86 and see if there are any errors. If you have errors, you either have bad memory or you need to manually configure your memory settings in the BIOS. Voltage, stepping, speed, etc.freesafety13

How many RAM sticks do you have? If you have 2 or more take them all out then put in one then start the PC. Shut off then add another and so on to try and isolate if one of your mem modules is damaged

I'd make sure to do a clean install of windows.

I've had memory test freeze and shut down on me before even though the memory was good.

I'd also try doing a Bios update.

Can even try adding some extra voltage to the northbridge and so fourth. Which solved my problem, which was from overclocking tho.

I'd say you download prime95 run a Blend test to test your ram and system. If it passes it means your ram is fine and the system is stable, should know in less than 5-10min. It also means it isn't hardware related and your windows is messed up with something you did.

MAKE SURE TO DO IT IN SAFE MODE! Removes all relations to Windows.

If it fails hardware remove ram sticks one by one and repeat test. If it still fails it could mean your rams bad or most likely your motherboard.

Last resort you could try increasing your voltages.

Part that are good for sure: CPU/PSU

What do you mean by post sound? Like the random beep you get when you boot the system? Then yes that's normal.

Well I checked the wire and it was in correctly. I also heard the speaker go off when I finished the hardrive test. What do you think the problem is? I hear no beeps at all. I do see the mobo screen and then the hardware monitor report after that and then it boots into my boot CD but thats it. No beeps. What do you think? Is there a way to test the speaker?Gamesterpheonix

I wouldn't worry about the stupid beep. Not all motherboards even come with the Beep or even need it.
