Hi guys, new to posting but I felt I had to try, giving this problem is driving me up the wall and I don't have the technical expertise to work it out for myself. I keep getting the, dun dun duuuum, ahem, blue screen 'o death, the physical memory dump. Now it does happen a lot more during gaming, but as I've just found to my frustration, not always. Just crashed while I was on msn with a friend running nothing else. When the comp restarts I do notice in the bios that (on the first screen) my two hard drives sometimes don't show up. If that happens I have to go into the setup and reassert the Master over the Slave as the first drive. If I don't the bios can go to the next screen and stop dead with a "disk error, do not pass go, do not collect £200" and I have to restart Now, like I say, I figure that might be something to do with it, but I'm just not that hot on computers. If there's more information I can provide to help let me know where to find it and I'll grab it, I'd really reeeeaally appreciate any advice, but if it were in small easy to understand non-technically advancde bits, That's be even better! Cheers in advance!
