I recently put together a PC with the following specs.
CPU: AMD FX-8320 (3.5 GHz)
Motherboard: Gigabyte 990FXA-UD3
RAM: Corsair Vengeance 8GB (2x4GB)
GPU: EVGA GTX 650 Ti Boost 1GB
PSU: Thermaltake TR2 600W
CPU cooler: Arctic Cooling Freezer A30.
I recycled a working HDD which had windows 7 32 bit installed on it.
After I put it together, I turned it on. Everything turned on perfectly and windows booted up to the desktop. However, when I went to do anything it shut down. No BsoD, no nothing, just as if someone kicked the power cord out. I let it rest for a few minutes, took out the power cord a few times, but it refused to start. Then after about 2-3 minutes it started up when I pressed the power button. Then the same thing happened, it went to the desktop and then shut down.
I Immediately thought it was a overheating issue. I went to the bios and saw that the temperature of the CPU from the bios was about 40C. I let it run for a few minutes in the bios to check if the temp spiked, it didn't. So, I closed the bios and restarted and same thing.
Then I thought it was a bios issue, I went to check the bios version and it said it was version "FB" and the date was 22nd of Jan 2013. I checked the gigabyte website and the last bios update was in july 2012, so I assume I would have the latest bios though I could not confirm through a bios version check.
I know that the PSU isn't faulty since it ran my previous PC without any issues. That had a core 2 quad intel CPU with a stock mobo and ram from the dealer. It had the same GPU.
After trying to isolate the issues by swapping parts with my old rig, the new one won't even start up anymore. However, when I hooked the PSU up to my old PC, it worked.
I don't know what the issue is.
Is it a outdated bios? Or that the PSU can't handle the load of the new rig? Or is it just a faulty Motherboard?
Any help is appreciated guys. Thanks for your time.
