Okay, so I am running windows 7 RC x64, however before you tell me it is a beta OS and it is the OS's fault, you should know that I had this problem running vista ultimate x64 as well.
Basically, every couple of days my computer randomly locks solid. My G15 keyboard loses power, and the screen is frozen right up. Sometimes however, (I think it happens after the CPU has had high usage) it will freeze and make a really high pitched noise at max volume out of my speakers. Currently I am connected to 6 studio sound stacks (huge speakers) so you can imagine that this is deafening and horrifying when it happens and I yank the plug to make it stop. I have gone through event log many times after these freezes and there is no event happening around the time of the freeze. I also turned my page file back on (I had it shut off because I have 6gb of RAM and don't want to waste my time with hard drive speed) I turned the page file back on so my computer could record logs, but it does not. It doesn't even say the system recovered from a serious error on reboot. It simply says that windows did not shut down properly. I am going to shoot myself here, because I am completely clueless at this point as to what is causing this issue.
Please help.
