I recently built a PC (see below for spec) and installed Windows 8, after ironing out a few issues by updating the bios I had this problem of when I first switch on the PC everything spins up for a second then stops for about 3 to 4 seconds then it boots as normal. I looked on Asus's website and came accross somebody else with the same problem and the answer they were given was to enable the XMP(extreme memory profile), so this is what i did and sure enough it cured the problem! After a while I decided I didnt really like Windoiws 8 so I decided to wipe everything and start again by clean installing Windows 7. After the installation I got my problem back, so I went to the bios to enable XMP to correct the problem, but after enabling XMP profile1 the system gets upto just before the windows logo is about to come up then reboots and just keeps doing the same. I am not super techy so I would appreciate any help I can get with a solutiuon to the problem!
