Severe System Instability

[Salavat23]

Hello there,

Recently, I have experienced instability issues with my system. I used to have it overclocked (E6400) to 3.4ghz, 100% stable. However, I have recently have been having problems. I constantly get BSOD (Blue screens). Even when I revert back to stock speeds and settings, I still cannot pass a simple Orthos or Prime95 test.

I have run Memtest86+ for 24hours. No problems at all.

My specs are:

Ultra 500W PSU
Gigabyte GA-965P-S3
Intel C2D E6400 @ 3.4ghz/stock speeds
Thermalright Ultra 120 Extreme
Mushkin PC6400 RAM 4-4-4-12@2.1V

What is the problem? Whether at stock or overclocked speeds, I still cannot pass 3 seconds with Orthos or Prime95.

If it helps, I am running Windows Vista Ultimate 32bit.

Please Help. I really need help with this.

Have you gone into your bios and actually setup your ram properly to its proper specs?

Yeah, but I don't think that it is a ram problem.

Here is what I have:

4-4-4-12, with everything else on AUTO. I am running the ram at its default specs and voltage (2.1V).

I am overvolting the Northbridge by 0.1v, and the fsb by 0.1v if that means anything in this case.

Please help.

Have you run a memtest to verify good memory?

First think i'd try is resetting the cmos, run it all at default, if that doesnt help perhaps your power supply is malfunctioning, if you have a spare plug it in and try that.

I have run MemTest86+ for ~24hours. This is BRAND NEW MEMORY.

But if it was the PSU, then the system would not start at all.

Try it and find out ;)

Incorrect.

If the power supply has a weak or low voltage on any rails it can cause system instability quite easily.

What are your temps like? Could be a chance that one of the clips let loose and the HSF isn't sitting right, or maybe plugged up with dust? Other than that I'd be suspecting a dodgy PSU, see if you can't borrow one for a night of testing.

My temps are great. Around 28c idle, 35 load with the Thermalright Ultra 120 Extreme.

I will try the PSU.

Is there any chance that this might be a problem with Windows, and not any hardware?
