I've been using computers since Win 3.0, but have recently built my own computer for the first time.
Generally, everything works great... right up until the point it doesn't.
Sometimes my PC will randomly just "lock up". The screen freezes, the keyboard is completely unresponsive (including ctrl-alt-del), the mouse cursor is the spinning circle. The only way out is to hit the RESET button.
It seems fairly random, and has happened while I was using iTunes, Outlook, or other programs.
The one constant is that every time it happens, I can see that the HDD activity light is *solid*. It's not flickering / blinking like with normal HDD access, just solid. I don't know whether there is something truly being accessed, or whether the solid light is just a red herring.
Also, I don't know if the system is actually frozen, or whether there's something hogging the system to the extent it's so slow that it appears frozen. It's a pretty beefy system, so whatever it is would have to be really doing a number. I've only ever waited like 2 minutes before giving up.
Given that every time it happens the HDD light goes solid, I have to suspect it's something with the hard drive subsystem, but I don't know how to begin troubleshooting whether it's a mobo SATA port issue, an Intel RST driver
issue, a hard drive issue, a cable issue, or maybe it's not the hard drive at all!
Here's some details (see more in my Systems Spec)
- Recently purchased DZ68BC mobo
- Prior to Windows 7 installed, verified mobo BIOS default was AHCI
- Installed Windows 7 64-bit Home Premium
- Win 7 appears to use AHCI
- After installing Windows, ran Intel utility to update/install all drivers, including Rapid Storage Technology drivers (did *not* update mobo BIOS)
- I am NOT running any RAID
Again, everything seems to work really nicely, right up until the point it decides to instantly freeze
It's hard to troubleshoot because it's so random, I don't know when to expect it, and after it happens I can't bring up any tools (i.e. Resource Manager) to see what's going on.
