Hey, i am new to the forums, But i am a fan of tomshardware. I am posting a very specific problem, I dont expect any immediate answers, but it will be a challenge. if anyone will know, you will. You people are some of the most knowledgeable groups of public techs out there, educated or not. - Here is the Dilema,
Gigabyte MA785GM - US2H Board.
Phenom II 9850 (2.5Ghz)
4GB DDR2, G.Skill.
x1950 Pro Radeon, And 470 Twin frozr ( read on, you 'll see)
550 Watt Fatality PSU
500Gig Seagate 7200rpm
A/C Aftermarket cpu cooler with AS5 compound. (heat is not an issue) max 50C idle 30C
Computer Posts, Boots Fine, and runs 3D applications with the x1950Pro, Though in 3d gaming i (after any extended time of running 3d Apps or games, detect artifacts in shading, models- ect. and one time froze.
When i install the 470, computer posts, boots, and runs on basic functions. as soon as there is demand, it is likely to freeze. Freezing symptoms are mouse frozen in place, and studdering audio( Sometimes audio will continue for 1-5 seconds, and then freeze .)
I installed the 470 into another computer and it runs perfect, the card is brand new.
If I remove 2 gigs of ram, the computer will run off of the 470 twice as long, and i might be able to get an hour of gaming in before it crashes. It doesnt matter what piece of ram i remove.
I RMAd The motherboard, thinking it was the boards issue.
Gigabyte was fast and helpful, after re-installing cpu ect, the computer froze upon startup.
Ok so its the CPU; i purchased an Athlon 940 3Ghz Quad core, and it worked for 30 mins or so, and then the problem re-occurred. unsure if the cpu was actually fried or not, (The comptuer would still work fine, as long as i didnt give it any stress) I Went into DOS and ran a utility called PC check. The cpu passes all of the daignostic tests, but when i run a stress test it instantly reports a fail on the CPU.
I RMAd that CPU. and got an Phenom II 3x 740, unlocked the 4th core and away i was, for 30 minutes, then the identical symptoms returned.
For the fun of it, I put the 2.5ghz 9850 back in (with The x1950Pro Radeon GPU), and did a PC check on it. This time, the stress test fails on the Hard Drive, and yet will pass all of the diagnostics, on the CPU and the HDD. Alright, things are getting confusing. Hard drive? where did that come from.
I'm at a loss now, I just RMA'd the Phenom 3x. It was only a day old. poor guy.
Most of you are pointing at my PSU. well, i tried a 600W fatality and it did the same thing. even quicker than before, Not ruling that out though. my system with the 470GTX only demands 435 -465 watts(i dont have fans, one HDD, and i've even tried with no DVD.
Recap:
Stress test fails on CPU with: 470 GTX twin frozr video card and Phenom 4x 9850 (Diagnostics pass, 3dnow, MMX, ect.)
Stress test fails on CPU with: 470 GTX twin frozr video card and Phenom 3x 740BE or unlocked, Phenom 4x 940
Stress test fails on CPU with: 470 GTX twin frozr video card and Athlon x4 940
Stress test fails on HDD with: x1950Pro Radeon video card and Phenom 4x 9850 (Diagnostics all pass, including Non-Destructive Write tests, SMART and read checks, really doubt there is anytthing wrong with my HDD. not ruling it out though.
im mostly leaning on a new PSU, But do NOT let that affect what you think it might be.
