I had many house power failures in last three weeks so my pc closed unexpectadly.i didnt use ups or surge protector.after todays power failure i opened again my pc and saw frame drops about 15 fps in games.im doing disk check right now and if it persist i will do a format.i have windows 7.so there is a chance that my graphics card,power supply,motherboard is damaged?i have only psu and video card warranty.my specs are psu corsair cx750m.gigabyte gtx 970.i7 2600k 2.6ghz.kingston 8gb 1333 mhz.motherboard gigabyte z68p-ds3 rev 1.
 
Solution
It would be weird for physical damage to a piece of hardware to affect how it performs. Normally a damaged piece of hardware won't work at all, and an I damaged one will work normally.
