I understand this is a windows 7 forum xD and I installed windows 8 on my computer. However im still having the CPU problem, I am experiencing severe lag, and experienced the lag throughout the clean install as well (yes, even after wiping my drives and making them "unallocated space" and adding windows 8 ontop after) the install pages were laggy and buggy, and now on my desktop and OS, although it successfully installed (after an extra attempt after an error) I finally thought I had got it. Howveer its still slow?!? what could it be? a corrupted hardrive? do I have to update my bios? please tell me I know its windows 8 now but Im stuck and really need help. I have two hard drives a 320 GB (unallocated as of now) and a 700GB (with the Win 8 on it). Should I try installing and booting the second hard drive see what happens?
If you have lag problems during (and after) the Windows installation with legitimate media, it sounds like a hardware or bios issue imho.
Test your harddrive with the HD manufacturers test tool, or use Seagate Seatools for DOS.

If you have a 5400 RPM HD, that will be slower.
