I put together a brand new PC. Turned out pretty good except the PC randomly locks up and freezes. I can make this happen by scanning the HD with MS Security Essentials, but it also happens at other times. I have to do a hard boot to get running again. You may have seen my other recent thread that stated the monitor was randomly going blank. That was not true, the power setting was set to turn the monitor off at 30 minutes. What was happening was the PC was locking up just like now except the monitor was already off (power setting). The power setting is now set to never turn the monitor off and the PC still locks up. The build goes as follows: AMD Phenom II X4 955 processor, Gigabyte GA-MA785GMT-UD2H MOB, 2 4 Gig Mushkin 1333 MHz DDR3 memory, Window 7 Ultimate, 500 watt PS, Nvidia GeForce 7300 video card, (I need to upgrade), and a WD 1TB Caviar Black HD. All of the drivers are up to date, cpu never gets above 54C, normally around 48C. The BIOS is set to load fail safe defaults.
uninstall the driver what chipset is it and cannot find this anywhere gigabyte ga-ma895gmt-ud2h from what this shows you have a amd 890 chipset now if you have amd 785g check your ram it can do it to Beside Asus' M4A89GTD, one Gigabyte 890GX-based motherboard has also jumped the gun and can be found up for purchase a few days before the (expected) launch of the AMD 8 Series chipsets. First seen last month, the GA-890GPA-UD3H is priced at $140 and features support for AM3 processors, four DDR3-1866+ memory slots, Radeon HD 4290 DirectX 10.1 integrated graphics backed by 128MB of SidePort DDR3 memory, and two PCI-Express x16 slots for CrossFireX or Hybrid CrossFire configurations. Gigabyte's oh-so-blue board also packs six SATA 6.0 Gbps and two SATA 3.0 Gbps ports, two USB 3.0 connectors, Gigabit Ethernet, 7.1 channel audio, FireWire, DualBIOS, and D-Sub, DVI, HDMI outputs
This happened to me once when the IDE Cable of my system drive was going bad. (Guess it didnt like all the unplugging and re-plugging.) Whenever the system lost access to the drive it just halted. Using a new cable fixed it.
Some more info: When I run a stress test with Everest, the screen immediatly goes blank and the PC freezes.
you can do a ram test on your next restart ..type in memory in the search and click on windows memory diagnostic
What bios version do you have, how outdated is it. Look at the website, read the fixes in the newr bios releases and see if anything jumps out at you.
My guess would be Bios, or HDD (or cable) or power supply. If you have another power supply give that a try. Some good hard drive diagnostics may be in order also.
Ran all of the stability tests in Everest individually. The only one that failed was the cache. I don't get it.
Swap out the ram and test, if you have extra ram. Also try different ram configurations (1GB, 2GB, etc). Switch ram around in the slots. I had a similar problem eons ago and it turned out being 2 of the 4 ram sticks had minor voltage fluctuations. Those 2 problems sticks had different chips on them but were still rated the same and from same manufacturer (Kingston) of the sticks. Once I got those 2 bad sticks traded for 2 more that had same chips as the 2 good sticks, all my problems were solved.
