This is a very bizarre situation. So I will list ALL the symptoms that I am observing and go from there... System Specs: AMD Dual-Core +5500 brisbane 1 GB Corsair DDR2 RAM Gigabyte S-series GA-M61PME-S2 Motherboard 1 Seagate 80GB system hard drive (the system boots from this drive) 1 Seagate 250GB storage drive 420W PSU CD-Burner Standard Heatsink I am fairly certain there are a multitude of problems, so I do not expect there to be a single answer/problem that would explain everything that is going on. For one, I occasionally get a BSOD followed by a physical memory dump, followed by a reboot. I am almost certain this is due to a failing hard drive. However, after recently adding 2 additional case fans, everything seemed to turn to chaos. Now, most of the time, when I turn on the power, the system will not post, I just get 3 loud beeps, and then nothing happens. I shut it off, and try again, same thing. The only way I can get it to boot is by randomly disconnecting and re-connecting things such as IDE cables, internal power cables, USB cables etc... The system will then run stably for a while (sometimes for a day or two, sometimes a couple of ours, and sometimes only a few minutes, it varies without pattern.) Inevitably, when the system crashes, I then continue to get the beep errors and it will not boot. I then have to go in and repeat this process of "messing with the cables" until it will boot again. My first thought is that it is a bad mobo, but then I started thinking that maybe the PSU is not giving the system enough juice? Any input would really help! I am probably just missing something... Thanks!
