The last 2 PCs I built have had the exact same problem, most components are different, but I think I keep doing something wrong. Some bios setting or something. Since then I upgraded the HD, motherboard, CPU, graphic card, sound card, etc. But the problem continues.
I never had this problem and I have been putting together PCs since 486DXs and the first pentiums. Very randomly, the computer starts to lag intensely to almost freeze. It lasts for from about 10 seconds to several minutes, sometimes a hard reset is needed because I would be tired of waiting. No bsod or anything, because there would not be a time to dump.
If it happens during a video playback, everything freezes for a couple of seconds and then the video "catches up" to the point as if it is being fastforwarded (kinda like VHS tapes effect if you are that old to remember) to where it should have been. Very weird. it can happen anytime doing anything, be it watching a video, browsing, music, etc.
Sometimes it goes for a month with no freezes, sometimes it happens like a chronic disease in every 4-5 minutes. it always reaches to a point that I have to make a clean install in 4-5 months because of corrupt files, especially if it happens during startup.
I researched and researched, tried many things and came up with nothing. The temperatures are all fine, I have adequate power supply, nothing was overclocked ever, changed browsers, changed other software, with windows drivers, with third party drivers, ram tests, hdd tests, replacing components, etc.
This is a via chipset AMD computer running windows 7 x64. I had the same problem when I was running vista 64bit, too. Here are the specs (all components are recommended ones from silentpcreview):
- Do not know the motherboard model number until I restart, but it was Asus with via chipset, most likely kt930 or similar.
- AMD Phenom x4 965
- Corsair 4x2 ram, the cheapest one, 1333
- Hitachi serial ata 7200 1gb
- Asus radeon hd 5450
- antec true power 650 inside of a antec solo case
- Scythe Mugen 2
I doubt that you're doing something wrong. There's two possibilities that come to mind.
It could be one of the components that you haven't changed in the last build, like the DVD player, or you keep installing a program that causes your problem, the latter being quite unlikely.
From what I can tell, you are using the same DVD, case and ram, correct?
If you're on this ignore list, vivahate, sd44, cav, charles052, frogstar, godfather927 don't bother quoting me
Does the freezing happen at a particular time, like when watching a movie or something graphics intensive? Have you downloaded a program such as GPU-z to monitor GPU temps while this is happening?
In addition to MemTest, I'd also suggest running a blend test of Prime95 for ~2hours minimum... but preferably closer to 8+ hours if possible. This will stress test your CPU and RAM to make sure that they are not failing when under heavy load. Additionally, you should also run a stress test on your graphics card using FurMark, and monitor the temps.
I believe I've found the solution to obesity in America. Hemispherectomy....no one uses it anyway.
