Hi all, I need help with a new PC that I have recently built. It keeps freezing up at random times. Here is what I have tried: 1. I ran the installation of Windows Vista Home Premium OEM -> it froze up during install 2. I tried the Vista setup again and this time it was successful. 3. After install, Vista kept freezing up at random times when I was using it (seems linke there is no pattern at all). 4. I ran a Windows XP Professional clean install after reboot -> froze up during install The above leads me to believe it is a hardware issue. What do you think? How can I troubleshoot it? BTW, I went to BIOS, loaded "Fail-safe" defaults and it made no difference. Below is my setup: Motherboard: MSI 790FX-GD70 CPU: AMD Phenom II X2 550 Black Edition (stock fan installed) RAM: Corsair XMS3 TW3X4G1333C9 4GB DDR3 2X2GB DDR-1333 CL 9-9-9-24 Dual Channel Viedo card: Gigabyte Radeon HD 4850 PCIE Power supply: Antec Earthwatts 650W Power Supply ATX12V V2.2 EPS12V ActivePFC 80Plus Case: Antec 300 Any comments or suggestions would be appreciated. Thanks, jarko
It could be a bad ram stick or video card, these things a hard to narrow down,You will just have test each hardware piece..
i had something similar on another 790 ram was the problem if not check out what are other bios version that will manage ram better
I think I got the issue resolved. Whenever I ran OCCT with medium or large data sets, it locked up immediately after the test started (1-3 seconds). CPU did not even have time to warm up. Small data set ran fine. I set the timings in BIOS to 9-9-9-24 2T. This did not help. Then I increased voltage to 1.7. It still locked up. But since I increased voltage to 1.8 it has been stable. I ran OCCT for both medium and large datasets and no errors/lockups. I was able to install windows updates no problem (before, it was guaranteed to lock up). My RAM is supposed to be rated at 1.5V (says right on the chip). Is it sufficient grounds for a return? Would you bother? Are there any drawbacks to running it at a voltage so much higher than the manufacturer's rating? Thanks, jarko
seems like you had stability issues generally down to not enough voltage. 1.7v will be fine as it just a cap the PWM will monitor that frequency and adjust the voltage to what's needed.
