What are your specs? What hard drive are you using?
Are you capable of opening task manager and testing it by opening an application. To see if there is any CPU usage or if it is just the hard drive.
Can you run a checkdisk
I've intel core i3 3220 processor(3rd generation) 3.3GHz, DH61 motherboard, 4 GB ddr3 ram, NVIDIA geforce g210 graphic card, 500 GB seagate sata hard disc.
yes i can open task manager, it shows cpu usage 10-15% max, even when pc is running so slow and i've also tried checkdisk, it checked disk removed some errors but even after that problem was not solved.
