Faulty CPU core?

[Erif]

Hi everyone,

My system specs:

AMD X2 7750 BE.
Gigabyte GA-MA78GM-S2HP (780G)
WD 120GB HDD.
Corsair 450W VX.
XP SP3 | Vista Home Premium

NO Overclocking.

My problem is that the system randomly freezes and reboots.

I've tried:

Exchanging the RAM Kit for another one.
RMA'ing the mobo.
Using another HDD.
Re-installation of OS, with various drivers.

But the problem still persists.


I was running Orthos, and after 2 and a half hours, the test halted & started giving beeps.
One of my cores, CPU #0, was showing an error & was in the red.


Can be certain that its CPU? What other software do I use? I ran OCCT, but that just gave me info on temps/voltages/rails.

prime95 would be another program but it does the same thing as orthos. maybe try memtest even though I doubt it would be the problem since you replaced the RAM. double check the voltages on the cpu too if the vcore is too low by default this can cause issues. I'm not entierly sure what it should be but I'm sure a quick google would give you the answer, you could also try to bump it up a little even if it's right if that solves the problem then I would say it's a faulty CPU. Also while you're running orthos have speed fan or something similar open the logging temps so you can see if the cpu is overheating as that could be another issue. Have you ever OC'd it?

Thanks for the reply.

Yes, earlier I had temporary Patriot RAM kit, which I exchanged for the GSkill.

My vcore is at 1.325V & was stable during OCCT. Temps go from 31C to 45C (daytime - summer heat)

Nope, no OC.



I had even sent it to the repair shop for testing earlier. They:
Tried different RAM/ HDD/ Replaced my mobo / Reinstalled OS.
They finally told me it was PSU problem.

Fair enough, I got the VX450. Yet the problem continues. (Since its random, perhaps they didn't encounter for while after changing the PSU. Hence, they reached this premature conclusion.)


Well the problem is that I ran Orthos for 4hrs again. But this time it didn't show any errors.


Is there any way I can be certain? I don't want to take it back to the repair shop and say "Its happening again, and I have no clue".
I want to go to them & say "I think I've got a lead, plz test it out further & replace if its faulty".

So, why didn't Orthos throw up an error this time? Should I run it again?




Also, will updating the Bios help? I doubt it will, but someone is continouslly advising me to do it.

I guess the easiest thing to do, if you're taking it to a shop is have them try another CPU. If it doesn't fail Orthos then I would assume it's the CPU but if the new CPU fails then the issue is elsewhere, obviously.

I typically run Orthos for at least 24 hours to test stability on my OC's I would do the same in this situation at least while you have the computer no need for them to run the test and charge you out the ass for just running a program.

a BIOS update *could* help, and honestly couldn't hurt, but I highly doubt it will fix the problem. But you might wanna try, just incase.

Ok, Orthos is running for a long time without any problems. Now what do I do? -_-

 

[Pantlegz]

I guess flash bios and/or run memtest. it's strange that you've got a whole new computer aside from the cpu and the problem persists. If neither of those solve the problem I guess replace the cpu, if you've still got the issue then I would say the computer is haunted and burn it.. lol

Great. Do you know any exorcists by any chance? (Or any counterparts from other cultures?)




Anyway, I'll take it back to the repair shop tomorrow and ask them to do it. I'm too exhausted with all of this to do it myself.
