PC that doesn't want to OC...at all!

[Curio]

I've been trying to overclock the wife's PC a little to help with Oblivion, but it's not having it. At all.

First I tried to overclock the graphics card (X700 Pro PCI-E) and it wouldn't even let me put a few MHz on the core without totally freaking out - it actually totally trashed 3DMark05....it reset the PC and wouldn't load 3DMark again I was wondering if it's because of the PSU. It's an Antec 400W, so plenty of power, but it's got the old style 20pin connector rather than the 24. I understand the extra 4 pins are for PCI-E power? Could this be why it's not happy?

Then I tried to overclock the CPU (P4 630 3.0GHz on Gigabyte Duo Pro board) and hit problems straight away. Even just using the Gigabyte software to put the CPU in "Cruise" mode made it freeze in Prime95 after a while - even tho the temps seemed fine. Select Turbo mode and the machine won't even POST

Basically, it doesn't seem happy unless everything is absolutely at stock. I don't think temps are an issue.

My system is totally the opposite - I managed to get my 2.6 P4 up to 3GHz with stock cooling and no problems. My video card also clocked very well with stock cooling. It was easy. The wife's PC seems to be totally the opposite

was ** wifes PC off the shelf or custom built? (btw Dell is off the shelf)

If its off the shelf sometimes the manufacter stops the system from being overclocked or modified in anyway. This is to stop people overclocking when they want a new Pca dn sending it back saying it doin't work. if this is the case ** in a mess.

It was custom built by my good self
