I'm building a new machine and it just doesn't want to cooperate. I've been building machines since the 80186 multi-user systems from Norstar days. I haven't built a new desktop in a few years though so I'm lost with some of the newer settings. Here's what I have
AMD FX8350 PIB (FD8350FRHKBOX)
ASUS MB5A97 LE R2.0 w/BIOS 2701
Corsair Vengeance 16GB RAM (CMZ16GX3M2A1866C9)
ASUS GEFORCE GTX750Ti (GTX750TI-OC-2GD5)
WD Blue 1 TB Drive (WD10JDVX)
Thermaltake SMART 700 P/S (
I also tried 2 new MSI AMD Radeon HD6450 (
Sounds like either a power supply issue, or there is a short somewhere. Take the motherboard out of the case and put it on a non-conductive surface, such as a cardboard box, and test it.
That looks like it. Thanks. Odd that no one at ASUS or their forum suggested that. I'm guessing that the problem is coming from the alignment between the board and the change-out plate for the built in ports. Found it. This case came with some snap-on stand-offs rather than the kind that you insert a screw into. They are 3mm longer than a screw stand-off, so something would definitely touch along the ports or the underside of the slot bracket area. Thanks loads. I've been fighting this machine for over a month now. I'm running memtest86+ 5.01 now (still on the cardboard box) with the CPU ranging from 45º-56ºC.
Be sure that the CPU temp that you are reading is the internal (core temp), not the "CPU" temp that is often the CPU socket temp, not the internal CPU core temp. Applets such as Aido64, HWiNFO and Core Temp provide pretty accurate FX temps in the 60C-70C range. The CPU socket temp can run 10C-25C higher than the CPU internal temp depending on load and duration.
The max user temp (internal core temp), for the 125w FX-8000 series CPUs is 61C. You should have no issue keeping the CPU below 61C under full load with the OE HSF. Make sure that you set the fans speed option in the BIOS or O/S to 100% or "full speed" so the fans can run at the appropriate speed for proper cooling.
The temp was what memtest86+ was reporting. It was only that high for about a minute running a test on all cores at once. Mostly it was high 40's. Thanks for the extra info.
