I have new parts I installed on my PC almost a year ago, the PC has been running good since last week ,I'm constantly getting a blue screen every time I boot , after the windows logo loads it freezes and restarts , I've tried a brand new HDD but a similar error occurs , I also tried a different HDD and same thing occurs so it can't be the HDD.I Also tried tested the ram trying different sticks and different slots, but same thing happens so it can't be that. I also tried the GPU using the display from the mobo (HDMI) but same thing occurs, the only old components in the PC are the mobo and processor they are about 5yrs old, the processor seems good and so does the mobo , so I don't know what it could be .HERE ARE THE NLUE SCREEN ERROR MESSAGES:IRQL LESS THAN OR EQUAL TO , DRIVER IRQL LESS THAN OR EQUAL TO , when using the new HDD and after the windows logo loads and its says beginning services (first boot) it's freezes and says a unexpected error occurs and the PC must restart and all you can do is click ok ,then it restarts . Please help me thanks
