Hi,

I've had my OCUK Ultima Panther system for a couple of months now and up until today it's been faultless. However I tried to boot it up this morning and encountered some problems. Here's what happened:

- Turned it on
- Started to boot as normal but froze on the Vista boot screen with the loading bar along the bottom
- Turned the PC off by holding the power button down
- Left it a few moments then turned it on again
- Gets to the Gigabyte screen where you can enter bios etc, then monitor loses signal, get nothing for a few seconds, then Gigabyte screen comes on again. It stayed in this loop until I turned it off again.
- I disconnected the power cord, waited about a minute then tried to power it back up
- I received an error message from the bios saying something like checksum error... Recovering bios settings from HPA
- It then gave me the option to start in safe mode etc etc or start normally so I started windows normally and everything booted fine.

So my PC is now working again but I've noticed a couple of things:

- I'm fairly sure it isn't overclocked to 3.8 GHz as it should be and has reverted back to default CPU settings.
- If I enter the bios and look at the overclock settings it comes up with an error message saying

"The system has experienced failures because of overclocking or changes of voltages.

Last settings in this page may not coincide with current H/W states. "



And I've noticed I'm now getting a high pitched whining sound through my speakers when scrolling through web pages, moving windows around etc...:confused: The sound card was upgraded to an Asus Xonar STX by OCUK when I ordered the system.

Really not sure what's caused all this. I haven't installed anything recently, haven't been stressing the CPU with anything at all, and haven't moved the PC itself at all.

Any help would be appreciated :confused:
 
I'm using an Antec 300 with 2 fans in the front, 1 in the back and the tri-cool exhaust fan in the top. Temps at idle were around 46 degrees C with the overclock, but they now seem to be around 39 without it.

If I look at the System information (Control Panel>System) for the Processor it says:
920 @ 2.67GHz 2.66GHz

My housemate reckons the second figure there should represent the actual clock frequency. If that is the case then it has never been overclocked to 3.8GHz as it's always read 2.66GHz there.
