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.

Hi try doing this http://support.microsoft.com/kb/331796
http://support.microsoft.com/kb/929135 you can also try running sfc /scnw http://www.vistax64.com/tutorials/66...c-command.html

Joe I will try those once it happens again. I am thinking I may have fixed it though, because I can't remember, but it may have happened after I got 4 more gigs of ram. Tonight I just installed a new CPU cooler and the computer froze during boot a bunch of times, and directly during windows start up. Then I got a bunch of blue screens, most of which had something to do with my RAM. So i swapped the locations of the 2GB and 1GB chips. (Yes, I do have them symmetrical as they are supposed to be). It started just find after that, so I am going to see how it goes. Something else to note is that when it was crashing and freezing during boot, my northbridge was around 115 degrees F. Now it is 104F (I two sensors in my case which read out to an LCD on the front, and I stuck 1 in the northbridge heat sink and one in my GPU heat sink)

Thats good troubleshooting. There are more than a few util's to read off your fan heat and other spec's. If you overheat you'll get all sorts of whacky bad results on your computer.

Yeah I use core temp when I get into the windows OS, because in BIOS my CPU temp reading is rather off. something like 54F? Core temp usually reports between 80 and 100 F

Hmm it is still happening... luckily my headphones were plugged in so it didn't kill my sound system.

HI can you attach your minindumps to your next post they may tell us something,copy them to a folder and zip it and use the advanced button on the post page use the paperclip icon to attach and upload them.I'am no expert on this will try to look at them and see if I can find anything

[CESMOtacon]

Hey sorry for delaying so long, these crashes do not generate dump files. I only have one dump file from about a month ago. I will upload it anyway.

Also, more information has surfaced- the sound isn't always a new sound, sometimes if I have music playing, the music will freeze in a loop of the current segment it was on. The computer experiences the same symptoms as before.

Hi have you updated the sound and video drivers

[CESMOtacon]

Video drivers yes, I recently bought a new graphics card. (HIS Radeon 4850 1 Gig) it's awesome. Anyway, I do not think I have updated my sound drivers in a while. I just went to ASUS's site and got some of the new windows 7 drivers, including a new chipset driver. I am also going to update my BIOS because my version is rather old. Hopefully my computer will survive this. I am going to use the ASUS EZ Flash for the first time.

Also, my new graphics card has lead me to believe that maybe my issue could be power related? It seems to become much more unstable when the GPU is being used intensively. I do not know what it is called, but do you know the 4 pin power connector on the mobo that plugs in separate from the giant power connector? Well that 4 pin connector comes with another 4 pins which you can snap onto it to plug into a total bank of 8 inputs on the mobo. I was reading my manual and I think it said something about that being able to supply more power to hardware which uses the 6 pin connector (which my gfx card uses) I will report back with my findings.

Hi post your psu info but just off the top of my head i would look at 750w as a good starting point but a good quality one,also remember that the stated wattage is not what you may get as a 20% tolerance is allowed so 750 then becomes 600

[CESMOtacon]

I have a 680 Watt Apevia PSU, can't remember the specific name. My system is back up and running, and I updated my sound and video drivers to the latest, as well as my chipset drivers. So we shall see...

[joeten]

Hi hope it goes well you know where we are so let us know

[CESMOtacon]

It has run just fine on idle for a bit, so now I am gonna try some GPU intensive stuff. (GTA IV and L4D )

[CESMOtacon]

Ran them both back to back. No crash. Time will tell if this is actually fixed.
