Hey all, I bought my brother a new system a few days ago, but he has had serious issues with the machine crashing ever since. The machine has had a fresh installation of Windows 7, it has all the latest drivers for both motherboard, sound, chipset and video card (Latest VGA driver tested as well as the latest Beta version) I thought the problem might be with the VGA card, as the computer would just shut off during 3d Gaming, but it also seems to happen when surfing the internet or doing normal "2d" activities What happens is the computer will just seemingly shut off, the LED lights on the front of the case, around the dials, start blinking and the only way to get it back up again, is to turn if off at the power supply unit and then turn it back on again. I'll paste in what my brother sent me (As I live in the UK and can't see the machine crashing myself), he said: I dunno what the issue is but, last night the comp just shut off in middle of game play on 3 different games, and the lights were flashing, I had to turn complete power off to the power box and back on to restart comp, I kept checking all my temps with speccy and speed fan and nothing seemed high at all, also when it shuts off and I re start it, a lot of my desktop icons move around to different spots, Update: crashed a few times on me, once playing euro, once just browsing Internet 5 min after the first one, changed out ram just for shots and giggles and ran euro on ultra for about 5 min and crashed. I dl a gpu monitor gadget, was accurate on temp but said the gpu was 0% but with just Internet would randomly jump to 99% or 40% then back to 0 and would stay and eventually crash Spec is: AMD FX-8320 3.5GHZ EIGHT CORE 500GB SATA III 6GB/S 7200RPM 16MB COOLERMASTER SEIDON 120M WATER COOLER 4Gb DDR3 / 1600 MHZ MEMORY MSI 970A-G43 AMD 970 CROSSFIRE AM3+ DDR3 USB 3.0 SATA CORSAIR 500 WATTS CX500 V2 80 PLUS POWER SUPPLY ASUS XONAR DG 5.1 CHANNELS PCI XONAR DG SOUND CARD AMD RADEON 7750 2GB PCI-E There was a concern I did have when I did search earlier, via this thread: http://www.tomshardware.co.uk/forum/330572-30-970a-warn... It's a different board/chip, but I wonder if the wattage of the CPU goes above 125W and causes problems on the board? Hmm I feel really guilty right now, because I bought this for him as a present, it was $700ish plus shipping etc and it's been nothing but problems ever since. I'm going to see what version of Bios he's running when he gets out of bed, but the Live Update software said there were no updates, but I'll have him check manually. Another issue I noted, was I sent him some ram before the PC arrived, which was: http://www.corsair.com/cmx8gx3m2a1333c9.html He originally put that ram in with the existing 4gb of ram, so I thought it "Might" be a conflict, due to them having a different Mhz value So I had him remove the 4gb stick that came with the PC As soon as he entered the bios, it froze and did so twice So he removed that ram and put back the original 4gb stick and the bios worked No idea if the two are related.
