If your pc is telling you that it will crush, you are sure it will happen. Like it happen to me 2 days ago. I saw it and to off set it, I re-format my desk top. My reformatting was a success and the fallowing morning my computer just broke down. No power and ac was not going inside my hardware but the monitor was on. I ask my cousin what to do and he told me that the power supply was not working. Thanks a friend of mine just gave me 6 months ago, a power supply from his old computer. Luckily almost same specifications and after changing the broken power supply with the acquired power supply my desk top is now working 100% percent now. Thanks God and I will not pay a single dime for it to run them again.
