Thermal throttling from hitting 100c on the cpu could be causing the 124 bsod at this point too.

Thermal throttling from hitting 100c on the cpu could be causing the 124 bsod at this point too.

I wondered about that, but I don't think so. It's getting cooler here now, and the Core Temps are running around 83C to 87C at the moment.
As of now, Max Temps are 91, 95, 98, 98C on the 4 cores.
Haven't done anything intensive at all, just a few tabs open in IE11 and running Vuze in the background...
 
I am however wondering about the Motherboard - after all, that's what feeds the CPU.
Another option is to swap in the other Core2 Duo CPU that I have - though I'd hate to lose 2 cores...
 
But I think I'll play in the BIOS after a good nights sleep and see how that goes.
 
On the plus side, I've only had 2 crashes since swapping CPU's - Before that, I would have had trouble just typing in a sentence here without crashing.
 
Oh, I'm not sure if I mentioned it or not, but I got my PSU Tester in the mail from China today. Not bad for $3.97 !  Postage included!

Good suggestions. What are you going to use the system for?

My main use is web surfing, but I also do a lot of photography and video work. Nothing fancy, mainly hobby. Lots of fishing videos
I have been using Adobe Premiere Elements, but my copy is hiding in a box somewhere since the last move.
Also use Photoshop a lot.
 

 
Hyper-threading may benefit your software - check with Adobe - as i5 does not support this feature

excerpt:
"Core i5 uses Hyper-Threading to make a dual-core CPU act like a four-core one, but if you have a Core i5 processor with four true cores, it won't have Hyper-Threading. For the time being, Core i5 tops out at handling four streams, using four real cores or two cores with Hyper-Threading."

Thanks for the links - great reading!
 

Well, I did a BIOS reset to default settings. Still getting crashes.
I bumped the Vcore voltage back up to where we had it a while ago and then ran the Intel Diagnostic Program - it failed because of high temps.
So I set it back to Auto and it is running much cooler now - still getting all the same crashes as before   
The question is, is this because of some change in the CPU itself, or is the problem to do with the lock-down clips not holding as tight as they should?
 
At this point I'm tempted to swap in the Duo cpu and install the after market Zipang Cooler.
Pension day is next week, so I'm thinking of grabbing an LGA 775 Motherboard off of Craigslist and just going from there.
I have 3 sets of DDR2 RAM that will work in this Motherboard, so at least one of them should be good.
 
I don't have the money to buy new at the moment, and will have to save up for the whole MB, CPU & RAM combo.
Right now, I just need a stable running computer, even if it is not as fast as a new one.
 
 
 

The reason for high temps = clips not holding tight like they should/too little thermal paste on cpu.
 
Since you're crashing with two different cpu's it's most likely the motherboard at this point. Your old psu that you replaced with a supernova 750w g2 most likely caused your gpu/mb damage due to out of spec ripple. What is psu ripple?

Most likely clips not holding tight - plenty of thermal compound on the cpu/cooler. I checked after first attempt to lockdown the clips.
 
Not sure about the PSU ripple - Only 2 PSU's in this unit - first was an Antec 850 Watt unit, second was an Antec 650 Watt unit. Both high quality (unless something went sideways inside).
Also, it has always been plugged into a high quality surge suppressor.
 
I'll have to see if I can find some place that can test the Antec 650 to see what sort of shape it's in...
At some point, I might even take the Antec 850 in to a repair shop to see what it will cost to get it working again. Found two shops that can do this, and one even replaces all the capacitors with new high quality Japanese caps.
 
But now that I have the EVGA unit, that will have to wait until I get the MB/CPU issue resolved...
 
Thanks again, Sajin!
 
 

No problem. Hope you get everything fixed asap. 

UPDATE
 
Last night I pulled the RAM out of the computer and put back just the G.Skill RAM, (both sticks).
 
Ran MemTest86 for a little over 2 hours and got 2 full passes, and almost a third - no errors encountered.
 

 
So, it pretty much looks to me like the issue is in the Motherboard...
 
Speaking of Motherboards, I've been checking some out online.
 
Looking at the Gigabyte G1 Sniper B7 which is selling for $125.98 Can$ - http://www.ncix.com/detail/gigabyte-g1-sniper-b7-lga-a9-126150.htm
I could then pair it with either a G4400 or G4500 LGA1151 CPU - http://www.ncix.com/detail/intel-pentium-processor-g4500-3m-c6-116973.htm
http://www.ncix.com/detail/intel-pentium-processor-g4400-3m-b8-116972.htm
 
Not the high end system I'd like to have, but one that would get me a stable system while I pick up the pieces for the system I want without pushing me to over-spend in a short period of time. The bonus is that I can re-purpose it for a home theater PC later on.
 
Used MB's on Craigslist have been pretty scarce or pretty expensive when found. The ones I've seen have been stripped down budget models. If I'm going to go that route, then maybe buying new will be the way to go. The real trick is to have the cash available when a good deal pops up.
 

Thanks for the update.
