Hey, I just built a new computer for myself and my girlfriend, and hers is getting BSOD randomly every couple hours, even when only downloading from the internet. When playing Lord of the Rings Online, the game itself was crashing every few minutes, but the computer wasn't.
The specs are:
RAIDMAX HYBRID 2 RX-730SS 730W ATX12V V2.2/ EPS12V SLI Ready CrossFire Ready Modular Modular LED Power Supply
ASUS M4A78T-E AM3 AMD 790GX HDMI ATX AMD Motherboard
AMD Phenom II X3 720 2.8GHz Socket AM3 95W Triple-Core Black Processor
After the BSOD, I ran the vista troubleshooting, which said it is a hardware problem, and that I should check the hardware.
In Prime95, after letting the computer run for only about 7 minutes on the "Blend" mode, the third core had an error and stopped running. It said
"FATAL ERROR, Rounding was 0.5, expected less than 0.4
Hardware failure detected, consult stress.txt file"
It's only reaching temperatures of 42'C for the CPU when the third core faults, and voltages look fine.
In the small FTTs mode of the test, all three cores passed the first little iteration of the test.
In the large FTTs mode of the test, the second core had the same fatal error after 9 minutes.
My computer and hers are completely compatible, so I'm wondering what and how I should test first. Would taking out pieces of her computer and replacing them temporarily with pieces of mine be a good method to test hers? If so, which should I do first? I was thinking of taking out and testing the RAM first. Then CPU. Then PSU and video card. If it's not any of those, it must be her motherboard, right?
Thank you so much for your help. I wish my computer could've been the unstable one!
I think you're on the right track. BSOD's are very often caused by unstable RAM. Did you manually set the RAM speed/timings/voltage to the manufacturers specs? Did you run memtest86+ overnight to test for RAM errors? If you haven't, those are the first two things I would do.
The Raidmax PSU isn't going to do you any favors either, but I would focus on the RAM first. For future reference, Raidmax PSU are junk and should be avoided at all costs.
If the RAM voltage and speed are set correctly in the BIOS then Memtest86+ should run with 0 errors. I'd RMA the RAM if you even get 1 error with the RAM timings/speed/voltage set to the manufacturers specs.
