I recently bought a built desktop. It worked great about about 1-2 months. I've been building desktops for years, and consider myself a quite experienced computer user, but this issue is beyond me. I've looked at some other threads with people describing similar issues, but none of their solutions were applicable.
Issue: When using some sort of resource intensive program, for example, a game, I can use for random amount of time before the CPU still start spiking to 100% on all cores for about 1-2 seconds, then run normally for another 2-5 seconds and repeat. It freezes everything, including the Windows UI. Closing the intensive process does not fix the issue, it continues until reboot. If I leave my computer idling all day though, the issue doesn't happen. My first though was overheating. So I checked the CPU and GPU temps during one of these episodes. CPU ~50C, GPU ~60C. Yikes, the CPU temp is a little high. I ordered a Corsair H60 and installed it hoping it would fix the issue. No luck. Checked the temps again during an episode after the new cooler was installed. CPU ~30C, CPU ~55C. Now those look fine. I have also been checking the processes list in Task manager to see if any process is doing this. Every time I check, the system idle percentage is always between 60%-98% the entire time. It is possible the UI just isn't updating during one of the spikes. I've also tried reinstalling windows and only installing drivers and one game to test other software being an issue, I still have the same problem.
System Specs:
Processor: Intel Core i7 3770k stock clock
Motherboard: ASUS Maximus V Extreme (Wireless and Bluetooth module removed)
RAM: 2x4GB G.Skill DDR3 PC3-17000 2133MHz RipjawsX Series
Video Card: NVIDIA GeForce GTX 670
System Drive: OCZ Vertex 3 60GB
Other Drives: 2x WD 320GB Blue in RAID 0, WD 1TB Green
Power Supply: 600W OCZ ModXstream
Optical Drive: Samsung Bluray Drive
I have attached a screenshot of the performance tab in task manager to illustrate what is happening.
