System Loses Power Randomly

EDIT: I just updated the BIOS to the latest version and it seems to have added these Kernel-Processor-Power events to my system Event Log in the Event Viewer... is this normal?
I thought they were already there. Isn't that why we're going through this process?


Did you read the release notes for the version? As I recall, some of those updates were for processor upgrades.


I don't know what 'Hard-Disk Write Protect' means exactly but it doesn't sound like anything I'd want to set/enable without checking. Look in your MB manual and see what it says.


AHCI is better but you can't just change it in the BIOS or the PC won't boot. You MUST use the procedure in the Tutorial below to change to AHCI. Follow it EXACTLY.
AHCI : Enable in Windows 7 / Vista


Added:
Did you install the chipset drivers when you built your system? This would have included INF installers for your hardware. It sounds like your problem goes way back.

^ Yes they were, just me getting over-excited from a new update and seeing things that have always been there.

^ Yes the release notes from the last 10 updates list major improvements in the CPU functions and overall system stability has been improved.

^ I'll take a look in the manual.

^ I'll follow this and let you know what happens. Just out of interest though, why should I be using AHCI instead of IDE?

^ Yes, I installed all the drivers from the CD that came with it, as well as any others from the Asus website.

If you ever reinstalled Windows, you would need to reinstall the chipset drivers.

As long as your drives are connected via a SATA controller, The AHCI (Advanced Host Controller Interface) mode improves throughput and implements additional features such as SMART technology and hot swap.

1. I've never reinstalled Windows

2. I will enable AHCI and let you know if I feel a difference!

Ok. Run your system for a few hours or a day to make sure it's stable. Be sure to include a reboot or two.

Then run a check disk with /r. After that, run a SFC /scannow. If these are clean then upload a new run of the DM Collector so we can get a fresh look at the system and events.

One thing i've only noticed because of my updated Marvell driver - My HDD is connected to a 6Gb/s SATA slot on the motherboard but on system start-up, after POST, the computer claims the speed is 3Gb/s. Are there any pieces of software I can use to test the data transfer speed of the HDD to the Motherboard?

Thanks

I would suggest not using Marvell sata 3.0 ports.
You probably have Intel sata 2.0 ports. Try them.
Marvell ports have cause problems for years. I know of no hard drive that can use the speed of a sata 3.0.

Your motherboard manual should show what ports are what.

To back up Layback Bear, unless you have an SSD there is no difference between SATA 2-3.

And for your question, HDDs have SATA 2 or 3 specs. If you can pull it out or know the model, you can check what interface it supports.

Hi Carwiz,

So i've been running it and it's been fairly fine. I have however experienced random freezes when I'm doing even the smallest of tasks, i.e. pressing 'Start'.

Because of this I have ran chkdsk /r and it found and fixed A LOT of bad sectors. Then I proceeded (after 2 restarts) to run SFC /SCANNOW - This found errors and was unable to fix them. I've attached the CBS.log file so you can take a look.

Thanks,
