Sounds like the rom drive is not up to scratch, or the ide cable, can you try another cable??
Also it could be that your cpu is overheating, what temps are registering in the bios??
Bloody newegg is giving 404 on the cpu link as well here so I don't know what it is, care to enlighten me please. Stock cooler on it??
Blasted newegg... Well it's an Intel e6750 2.66 g. And I replaced the stock fan with: http://www.newegg.com/Product/Product.aspx?Item=N82E16835200013
and it keeps the temps around 40 degrees Celsius.
Well I have to go to bed for tonight, I'll be back tomorrow... thanks for helping so far (especially A True Folder).
