Okay,so I have been using this setup without a problem since mid 2008 (does not seem that long). About a month and a half ago my computer started to randomly lock up. Screen would freeze, sound would freeze on either no sound or a screech. Nothing short of a reset will do anything to it. But if I press the reset button everything will start to fire up for about 5 seconds then shut down again, start to fire up again but the LCD on the mobo stops at 7F and there is no display to the monitor. The only way I have found to get around that is to reset the cmos, then it boots fine. This problem has become increasingly common, but is very sporadic. Sometimes it will go days between issues, sometimes it will do it 3 days in a row. I reformatted my harddrive to see if maybe I had something on there that was causing problems and I have had a lot of stability problems since. I will get errors when I try to install stuff, things dont run stably, etc. I have done error checks on both harddrives and run memtest on the ram and everything came up fine. Recently I have been getting more random issues. On some bootups now I get a C1 error on the mobo lcd (which is a GPU error) and I have once had a 9.0 error (bios issue). All of these seem to be temporarily fixed by clearing the cmos. Then yesterday the temperature display on the front of my case died (bios temp sensors seem to be fine).
The broad range of issues seems like it might be a motherboard issue to me, which I am really not looking forward to replacing. However, some other things I have read point to RAM or GPU. So before I go buy stuff and tear this thing apart I wanted to see if any of you had any ideas about what the issue could be? Thanks a lot and I appreciate the help.
