Random System Shutdowns
Problem: Computer shuts down completely at seemingly random times without error mesages. Blank screen, no cusor. By "shutdown" I mean totally off, the restart button does not work, need to use start button.
Symptoms: Shutdowns occur when/on
- startup, get a motherboard company's (XFX) splash screen then shutdown
- get past splash and into POST/BIOS log screens then shutdown
- get past bios log, opens in safe mode then shuts down before any choices are made
- gets to screen allowing selection of safe modes or normal windows boot, either choice results in shut down
- On rare occasions I can get into safe mode for a bit then shuts down
- on very rare occasions windows 7 starts then shuts down at random spots after about 1-2 minutes or less.
- I seem to progress farther into the boot process if I pull the AC plug and plug it back in.
.
When it started: I upgraded from Vista 64 to Windows 7. All went well until I was testing if some older games would run. Part way into Half-Life 2, Episode 2 then the system shut down (that may not be related to the game though as Neverwinter Nights 2 MOB worked just fine). My Vista 64 had worked perfecty for over a year.
What I have tried (other than unpluging AC and replugging)
- Tried to make some memory and CPU speed/clock changes on the few times I could access setup before shutdown.
- Uninstalled non-compatibles
- Drivers are up to date.
