I've already told you guys that I have a 64-bit operating system. It's Windows Vista Ultimate x64. I have 5TB of HDDs, which I'm pretty sure you can't even do on 32-bit? And anyways, I know what I'm running on.
I replaced the RAM, this one, yet again, only detects 2 of the 3 sticks. This time I got a 12GB kit, so it's only detecting 8GB of it.
My motherboard can't actually boot with a card in just the first slot, but with two different brands and two different sets of RAM, it's pretty obvious I have a bad DIMM slot. In fact, only the black slots work. When I tried putting the RAM in the blue slots, it just put the computer into a permanent restart cycle, like a bad clock. Except, it never did come up. Once I'd switched them back to the black slots it even said there was a bad clock and reset all my timings, which is weird.
And anyways, I'm pretty sure letting it do that for about 2 mins or so fried my HDD. It started clicking really loud not long after and I was 4 days without a computer while waiting for an Advanced RMA. I ended up getting a new one from Best Buy and cloning to it instead since it was going to take yet another 4 days because of some shipping delay. I actually just now got all the hdd crap sorted out...
But yeah, it really looks like it's a motherboard problem. Even eVGA (my GPU's support) and Crucial (my RAM's support) have told me it's the motherboard. Unfortunately, MSI is just dicking me around.
OC stable, tried unclocked too, problem persisted. Like I said, it's not the CPU. I've benchmarked that too and it doesn't overheat.
GPU I've benchmark tested and it doesn't overheat, and it's not overclocked, no.
Oh by the way, I guess I never posted this...
Mobo: MSI X58 Platinum SLI
GPU: eVGA GTX 280
PSU: Kingwin MACH1 800W
And uh, since I replaced my RAM now... this is it...
RAM: Crucial 12GB kit (4GBx3), DDR3-1333
I was doing DDR3-1600 before, this.
This problem is getting pretty expensive at this point... $150 to get new RAM, $100 for another hdd since I couldn't stand another 4 days without my computer. So... $350 and nothing has been fixed. RAM still isn't all detected and I haven't tested yet, but I'm pretty sure it probably still freezes too.
