So today i bought new cpu i5 7400 to replace my pentium g4500 3.5Ghz.

Last night my pc was working perfectly until i slapped the cpus..
When i installed the i5 7400 my pc keeps restarting.. I dont know what can be the problem.
I removed the battery to clear the cmos and it keeps restarting and black screen. Thats all.

My PC specs
CPU-Intel pentium g4500 3.5Ghz (new cpu i5 7400)
MOBO -asrock h110m dgs
GPU- gtx 770 2gb lightning
2TB HDD
120GB SSD
4GB ram 2133mhz
550w power supply

I put my old cpu and it just boots without screen, even ny gaming keyboard and mouse doesnt light ans work ...
