Okay, here's the story. My computer has a track record of dying, and especially of blowing up power supplies. This all started when I got DiRT 2. At the time, my system was pretty standard. In fact all I had changed was the graphics cooler to a Vortexx Neo, and added a rear exhaust fan. Even the AMD cooler hadn't been moved from when it was fitted. As a result of this, DiRT 2, which stresses my CPU far more than my graphics card, started causing the CPU to overheat and the system to shut down. It did this a couple of times until while checking that the CPU was in fact overheating, the CPU overheated... and died. Oh joy of joys. So I did what anybody would do, dropped some cash on a new CPU, the 6000+ in my sig, and a Freezer 7 Pro to keep things chilly. Unfortunately, after a few months of solid running on my Winpower 440W PSU (Y'know... those ones you can buy for about a fiver? Admittedly it did give me a good few years of service...) I am playing DiRT 2 happily and the computer shuts down. No worries, I think, maybe something just overheated. So I let the rig cool off and fire it back up, and I am rewarded with the sound of the power supply exploding. -.- I take it out, and get a cheap replacement, an EVO Labs 650W modular PSU. A step up, thought I, but it was not to be. Merely two hours after getting the system nice and happy and deciding to test the stability (with DiRT 2) and then it shuts down again. My heart sinks, and it does even more so when I am rewarded with the BANG of another power supply exploding when I try and start up again. By this point, I thought I had done something wrong. Maybe I had wired it wrong? Maybe something shorted? I'm confident in my abilities to put together a PC and diagnose the issues and stuff, but I wanted a second opinion. So I RMA the PSU, and hand it over to a friend of my dad's, who confirms that everything was okay, and puts it back together and sends it back to me. By this point, I thought I would just leave the rig alone for a while and see if anything happens. Cue a couple of months of contented running before, while idly playing Assassin's Creed, it shuts down again. Gah. Another wait, and another BANG confirm the death of another PSU. I lucked out however, and gratefully received a 700W Silverstone Strider (Thank you! ) and dropped it into my system. I decided to be careful and not play any games until I could assess what was wrong with careful testing. I thought it was the position of the PSU, for a while, as my old case had it mounted in the top, sucking hot air in from the Freezer 7 Pro, but my new case, the M59, has it floor mounted, so overheating is far less likely. My suspicions finally fell on my new CPU, the 6000+ I had bought. I knew it was a higher TDP (129W!!!) than my older 5200+, and that my old Biostar motherboard was cheap and had a very very basic power system. I got to thinking that maybe the power load was too much for the motherboard, and somehow it was taking out the PSU? Before I got any real testing done, my worries about the cheap mobo were confirmed when it burned out. Oh joy of joys, I thought to myself. I looked around and bought a shiny DFI AM2+ motherboard. I chose this one because it was fairly cheap, what with DFI going out, and the CPU list, while not mentioning the 6000+ under supported, does support various other AMD CPUs with 140W TDPs. Perfect, thought I. And here we are. My system seems to be running fine. I've had 8+ hour sessions in TF2, played FUEL and L4D2 for hours, and even raced a bit on DiRT 2. What I can't do, apparently, is relax when playing DiRT 2 on this system. It's killed two PSUs, and it puts my CPU under the heaviest load of anything I frequently play. This system has been through various benchmarks to test stability, but part of me doesn't want to relax when playing DiRT 2. Which is a shame, because I love that game. So, your verdict, ladies and gentlemen... am I being too cautious? Have I likely eliminated the weakest link? Should I just forget about it, crank up the volume and fly around the tracks? This is a hella long post. For the ADHD amongst you (and me)... tl;dr: My computer's broken a lot, but I think I fixed it, but I'm not sure.
