Thanks a lot of those links. Invaluable. I'll see if I can make a bootable USB drive with them on.
I've been building/upgrading PCs since back in the old 386sx days. I've done pretty well when I can honestly say this is the first major hardware failure I've had on any machine I've either upgraded or built for myself or anyone else. I've had the usual windows issues, virus's, MBR issues etc, but this is the first hardware failure.
I've found that the pace of technology improvements has pretty much outstripped the life of the machines and what people want to do on them.
And true to form, this is the first PC build where I've gone without any form of optical drive, installed. When I built it going on 4 years ago, I pretty much saw everything moving towards online storage or portable storage, so I've been building up my USB tools library, down to full windows install USB's, but CPU tools is one I've been missing. So thanks
