Random resets Windows 7
Greetings and congratulations for the good job in the Forums.
My PC is having random resets for quite a while now. No specific trigger, no pattern, except that it mostly happens when systems is on light load or even idle. Sometimes it happened once in a week and sometimes 3-4 times in a day. I tested CPU, RAM and video card with various stress testing programs (Load Tester, Orthos Prime, Furmark, VGA Memory Stress Test, Goldmemory, Memtest86+, Memtest, Windows Memory Diagnostic) without problems. Tested HDD with HDD Regenerator and it was ok. Recently, I tried a Windows reinstallation. After booting from the Windows DVD and loading the initial files, the PC had a reset when it was idling for a couple of minutes at the first screen of Windows Setup! I re-tried and installed Windows successfully. With the new installation, with no drivers or updates installed, the random resets kept happening. After doing a second Windows reinstallation the situation is the same. I have gradually replaced all replaceable hardware components with known-to-work ones, except for the CPU and motherboard. I replaced PSU, RAM and HDD (and its SATA cable) and added a dedicated ATI HD 4350 Video card. Updated to latest BIOS. Disabled integrated components from BIOS (LAN, Onboard VGA and Sound, USB controllers). My latest actions were to detach the motherboard from the case to rule out any short circuits and to remove all unnecessary devices. At this moment the system is out of the case and consists of the essentials (PSU,motherboard,CPU,RAM,dedicated VGA,HDD). The resets keep happening and almost all of them are described as follows in the Windows Event Viewer:
"BugcheckCode">0
"BugcheckParameter1">0x0
"BugcheckParameter2">0x0
"BugcheckParameter3">0x0
"BugcheckParameter4">0x0
"SleepInProgress">false
"PowerButtonTimestamp">0
Any help would be appreciated. Thanks in advance.
N.B.: I am attaching the logs from SF Diagnostic Tool after the second Windows reinstallation. I could attach the logs from the previous installations if needed.
