Win 7 Home Premium x64 Randomly Freezes requiring hard boot
I recently upgraded my own custom built PC by replacing the primary HDD with a 500GB Samsung SSD, a new graphics card and installed OEM Windows Home Premium x64. From the beginning, I have experienced random freezes that require a hard boot, at least once a day. There’s never a BSOD. The freezes occur while I’m browsing, playing games, or doing nothing at all. The computer will crash immediately in sleep mode and restart, so I have disabled the power settings. I don’t know if that’s a separate problem or not. I built this rig in 2007 with XPSP3 that worked more or less fine for years.
Here's the rig:
OS Windows 7 Home Premium 64 bit CPU Intel Core 2 Quad Q6600 2.4 GHz Motherboard Asus P5N-E SLI Memory 2 x 2GB Graphics Card(s) Gigabyte GTX 750 TI 2GB Hard Drives Samsung SSD 850 EVO 500 GB My power supply is a 600WCooler Master RS-600-PCAR-E3.
I have updated graphics and WiFi network card device drivers with no resolution. My HP 2575 all-in-one drivers seemed to be involved (Event viewer), so I completely uninstalled them. No help.
I’ve looked for the dump files, and there is nothing in there - ever. (show hidden files is checked. If anything was there I would see it).
I’ve gone to the Startup and Recovery Settings and set the “write debugging information” to:
Small memory dump, uncheck automatically restart, and set the small dump directory to”
%SystemRoot%\Minidump
There’s no memory.dmp file either.
The event viewer consistently shows two things:
Critical: The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly. (8:35:25 AM on 6/13/15)
Error: The previous system shutdown at 8:05:58 AM on 6/13/2015 was unexpected. (8:35:34 AM 6/13/15)
When I look for an event at the time 8:05:58 AM on 6/13/15, I don’t see anything.
It’s the same pattern whenever this happens.
WTH is going on? Help would be much appreciated.
