Hi, On Thursday a bootup problem occured, where the point where the OS should start loading, ie at the point after 'Verifying DMI Pool Data....' it just stops and does nothing. The first time this error occured, the problem read: "A disk read error has occured Press Ctrl+Alt+Del to restart." Since then, it doesn't say anything, just stops there. In BIOS it only picks the drives up as 127.99GB drives, even tho it's 250GB. What I've attempted so far: Using another 160GB SATA drive. Buying another motherboard, testing it, same problem. Flashed BIOS, cleared CMOS. Erased previous DMI data. My system specs: GA-K8NF-9 motherboard AMD Athlon 64 3000+ 1024MB Corsair RAM 250GB SATA NCQ HDD Radeon x800xl 256mb PCI-e Any help or suggestions will be greatly appreciated. Im guessing it's the RAM.
