Hello,
I've experiencing for the last 3 months a problem that drives me crazy, I cannot seem to find any solution. My PC:
- Intel Core2 Quad 9300 @ 2.50GHz
- 2x OCZ DDR3 @1333 (before: 2x Kingston DDR2 1GB @800)
- AsRock 1600P35 WiFi+ (http://www.asrock.com/mb/overview.asp?Model=4Core1600P35-WiFi%2B)
- Gigabyte GTX 275 (before: Nvidia 9800GT & ATI 4650 chip based graphics cards)
- 320GB WD HDD @7200
- Thermaltake 750W
In the meanwhile I have switched (or have been running simultaneously) 4 O/S (XP Prf 64b, Vista Ultimate 32b & 64b, 7 Ultimate 32b). The problem is the following:
While running in Windows environment (surfing with Mozilla, etc.) or playing a game (anything from PES10 to Fallout3), the PC seems to get into a CPU slowdown, it gets stuck multiple times per second (5+ per sec), so that everything goes slower and with bumps. It seems the CPU load is over 80% while the sum
of the values from the CPU flag from all the current processes is at most 15%.
However, apart from that everything keeps running normally, the HDD does not seem to load anything, and I usually solve the problem by opening the task manager and closing the application I was running (f.e. the game or mozilla). The applications is responding normally even before I close it, ofcourse not running smoothly.
If this happens for 3-4 times per day, on the 5th time this happens or so I usually have to wait for 3-5 minutes after I've closed the application, for the system to "cool down" (??) and run smoothly again.
The problem appeared with all the different hw (RAM, graphics card) above. I tried to check DPC latency with DPC Latency Checker, and I get the following:
- When running heavy apps (f.e. CUDA apps) i get some 16.000+ μs bars every 6 secs. The application is running smoothly at the time.
- When the problem stated above appears (even if surfing in Mozilla, or running a game) I get constant 16.000+ μs bars, until the PC runs smoohtly again.
Can anyone please help on this one?
P.S. My MB is also running with high temperatures, after the system experiences the above problem I have restarted and checked temperature through BIOS, and it goes up to 120F (usually aroun 114F). Is this normal?
