Gigabyte GA-8I915P DUO PRO RADION X600 PRO 2xHDD SATA RAID0 here goes... For quite a few months I have had sticking at regular intervals. Everything freezes for a few seconds and this happens every 3 or four mins. It occurs even when the system is idle. Afterward everything moves very quickly to catch up. Typing is not such a big issue because it will just catch up after a few seconds but music, games, videos are all annoyingly interrupted. I am running P4 with HT so in windows task manager, performance I can have two graphs. The freezes correspond to a full height, clipped (ie flattened by top of graph) peak on the left graph. In processes, System goes to CPU 50 but none of the .exe seem to be the culprits. Also at the same time HDD light goes solid on. Drivers a relatively uptodate I have tried: various page file setups - currently system managed cachman diskeeper boot time defragmentation windoctor-nothing scandisk-nothing disabling all startup items in msconfig unhooking all drives but the HDDs happens from start up and with case open - so not heat RAM one stick at a time Interestingly with one RAM stick I got a BSOD. "Windows has shut down to protect ure computer", "STOP: 0X00000001......etc." Seems to be running fine on one stick now though. I'm on the verge of calling MS Tech support, so you know I'm on last resorts. Any ideas

Dros !!! When you set up the raid array what cluster size did you choose ??? IF IT AINT BROKE, DONT FIX IT A8N-SLI Deluxe AMD X64 3500+ Wnchst Corsair 2x512 DDR400 Dual Channel GV-NX6600128D PCIX Graphics Card Ggbyte GT Pro CPU Cooler Zalman VF700-CU VGA Cool

cluster size is 128KB. Initially everything ran fine

oh... I have also run memtest86, Norton antivirus and Ad-aware.

Well your cluste size is at optimum, thats fine. From what you described I might suspect ram, or heat issue. I asume you have connected the additional powr connector for the graphics card. I am strating to suspect errors within one of the ram modules, I presume they are the same type and brand ??? the fact that you got a BOD with one of them suggest's a bad stick. With 2 of them on dual chanel they will play up only when that specific part of the memory is used. Now Im going to tell you another thing. I came across an exact same issue with 2 512 modules of Kingmax on a GA 8IPe775 Pro, board, after 6 moths. I also had one of these fail only after 4 weeks with exact same setup, for no reason whatsoever. Gigabyte have the board at the moment and for some reason they seem to be stalling, Try swithcing off the auto fan controll if you have it engaged, adn see if that makeds any diff. How are your temperatures. ??? You seem to know your way arround so try this. Desable all from the startup group that you can, except anty virus and pc protection. Once done set the page file to NO PAGE FILE. And reboot, you should be ok doing this with 512,and see if you can run without it. If all runs ok set the page file size to Min 768 and MAx 1536. Which I think you know already. Remove any second party managemet software if you can. As for memtest did you try testing each ram module on its own at boot up ??

OK.... RAM passed test individually. They do get pretty warm but thats normal right? According to BIOS CPU temp is <50C Set PF to 0. On boot up I got an interesting error; "Generic Host Process for Win32 Services encountered a problem and needed to close". Strangely WTM reports PF Usage as 200MB. Maybe it is just confused by the lack of page file. The regular CPU spikes are still coming with no PF although they have moved to the right graph. I'm now going to put PF to what you said but since the spikes occur without a PF maybe it is not to do with that.

The ram geting war is ok, it does a lot of work on dual chanel, warm yes hot no. You didnt say if you are using ddr or ddr2 ram ?? And I presume they are in thir respective dimm slots. By rights you shouldnt get that sort of error message page file or no page file !! Not sure why your are getting page file usage with no page file set !! As for the cpu spikes, they do happen as the background services do what thye need to do, but at most you should only get a spike upto 50% for a split second, this I suspect could be the echo ping to the modem, if you got one hooked up. The cpu temp seem about normal, for the prescot. If you are satisfied that all hardware is the way it should be the only other thing I can suggest is to reset the bios back to fail safe deafults, and see if that makes any difference, but if you do make sure you set the raid setup in the bios only the way it should be. If you havent done so already update the bios to the latest version available from the web site. Set the cpu warning and shut down temps in the bios to about 70C just to make sure this is not causing some problem. If you still have no joy, try and do a clean insatll again if you can. If you drives are partitioned, dont delete the raid array, but what I would suggest is to delete the primary C partition only than recreate it. This will blow the C drive away and any problems that may exist with it. And if you get any errors while loading windows, like unable to decompress file, or DLL errors than it is your ram. From here there is little else I can point you to at the moment.
