I just had a PC custom built from a store like 2 months ago. But i have been getting 0x0000f4 blue screens errors since I bought it. So I decided to check if my hard disk is all right. First, I downloaded CrystalDiskInfo and it didnt detect my hdd. Then I downloaded speedfan which make my computer go bluescreen as soon as I opened it. Finally the software HDDScan detected my hdd. I run the smart test and it got all green. I tried another software - Seagate tools. I run the smart test and it says it failed. Which one is right? Is my hard disk failing?
