Hello all. This is my first post, so pardon if it's in a wrong section or something.
My PC is custom built; here are the stats:
Intel i5 2500k unlocked processor 3.3 Ghz
EVGA Geforce Gtx 550 Ti
Cooler Master Gx 650W PSU
2x Corsair XMS3 4GB RAM sticks (8 total)
OCZ Vertex 3 120 GB SSD primary hard drive
Western Digital Caviar Black 750 GB secondary hard drive
I have the following monitors attached to the Gfx card:
Acer s230HL 23 in
HP 2311x 24 in
Anyway I just moved my computer rig to a new apartment, hooked it up more or less like it was before, and for the most part it worked, except every so often, usually when watching a youtube video, my computer would freeze. The manner of it freezing was bizarre though. The computer didn't blue screen or even completely lock up. Rather, I could identify the audio from the video I was watching was still playing at 10x slower speed so it sounded like my computer was possessed. After a few minutes, however, my computer would start working again, and aside from a temporary disconnection from the internet, it was a-okay. But it was really annoying, so I decided to diagnose. After browsing a few forums, I noticed that after each of these freeze-ups, my CPU (Intel i5 2500k) showed 100% usage on all 4 cores for a brief spike, and the resource monitor showed that the cause of the spike was whatever application was running video (the freeze happened in chrome.exe, vlc.exe, and sometimes in games I was playing).
I thought that I messed up some hardware while transporting my rig, so I opened up my computer, dusted all the parts, disconnected and reconnected the gfx card, sound card, and cpu cooling fan, and even bought some thermal paste. I then updated drivers, bios, changed hardware acceleration options. After each of these steps I checked the computer and the same problem persisted. What was odd was that I couldn't trigger the problem on command, it happened whenever it felt like it, and lasted for as long as it felt like. Sometimes it was 5-10 seconds, and sometimes up to 4 minutes. I finally decided to check the monitors, and the HP turned out to be the culprit. After making sure it wasn't the dual display setup (I tested each monitor by itself) I figured that the HP monitor was causing the freezing. But I don't know why. It wasn't the DVI cable I had running to it either as I had switched the cables between the monitors.
So my question is this. How is this monitor causing my Gfx card to force the cpu usage to 100%? I'm certain it's not a compatibility issue since I have been using that monitor for years, and this problem only started after I moved. Could it be that I broke something inside the monitor?
