I've had my AMD FX rig for less than a year and from day one I was plagued by random crashes during gaming, sometimes it came up with a BSOD, sometimes a black screen then CTD. I have replaced the following components:
- GPU (Now HD7770 GHz Edition)
- RAM (BSODs and CTD occur with both sticks in all slots)
- SATA Cable*
- PSU (From El-Cheapo to Cooler Master)
And have made the following changes:
- Set memory ICs to Unganged
- Set LLC to 'Extreme'
- Reformatted to Windows 7
- Underclocked CPU*
- BIOS is up-to-date with F6
- Graphics drivers up-to-date with Catalyst 12.10 drivers
- Memtest86 passed
- Ran OCCT a while ago with no errors, but can repeat if needed
- PC is generally stable for web browsing/Office etc. (unless underclock applied - see below)
* = Issue occurred less after that, then gradually came back with increasing frequency
At first, I thought the issue was graphics card related, so I spent £40 on a HD5570, then £80 on a HD7770 to try and resolve the issue, neither did.
I was then advised by a number of members on the forums that it could be down to the PSU, so I replaced it, but the issue still occurs. The power supply is more than required, at 100% CPU, GPU and RAM load my system should draw 400W, and I have a reputable 500W PSU.
Yesterday, I tried to sort out the issue by replacing the SATA cable (suggested by bp9801), and I thought the issue was solved, but alas no, this morning the issue recurred with increasing frequency. I then underclocked the CPU from stock and managed the system ran fine, but again, the issue came back after a while. Any attempt at a further overclock would cause Windows Explorer to encounter an error before even loading the desktop. I have cleared the BIOS to fail-safe after this.
I have no idea which component is causing the issue, and as you can see, I have made a number of purchases to attempt to resolve the issue. This is my only DDR3 and SATA rig, so I haven't got a spare HDD or RAM to test, nobody I know will have a spare AM3 or AM3+ CPU and I can think of nothing else that is causing the issue, except perhaps a PCI NIC, although I doubt that would cause this much of an issue so I haven't tried anything with it.
I can post a video if you think it will help, sometimes I get a BSOD, and have attached the minidumps, but if a BSOD does not occur and the system simply locks up and I have to manually power off the rig, or I get a CTD, there is no error. There do not appear to be abnormally high temperatures on any components before the crash, nor any strange voltages.
I am awaiting a reply from Gigabyte, my motherboard vendor with regards to an RMA, but I want to be sure it is faulty before I pay postage and waste time with a pointless RMA. I don't have any money to upgrade to Intel, hence why I went with AMD, although with hindsight, I probably should have gone on the blue team.
Any help anyone could give would be really REALLY helpful

Update: Issue traced and resolved, despite Memtest86+ pass, issue was RAM
