I have a PC I bought from Canada Computers about a year ago. I am starting to upgrade the components inside. I replaced the GPU and the PSU with no problem and have run well for 3 months or so. I wanted to upgrade the CPU next, so I researched and looked into what I can install. The socket is LGA 1150. I purchased an i7-4790K to replace my i5. When I installed the new processor and heatsink and started up for the first time, the fans all whirred for a brief moment then shut down, this repeats over and over till I pull the plug. The CPU fan does not spin. Not sure if I had done something wrong I went back to the old processor to test and see if the machine would still boot. It booted normally with the heatsink from the new i7, which spun up and ran normally. I am assuming it is a bad CPU. Is there anything else I should check? My motherboard does support the processor, I pulled out the battery that was on the motherboard for an hour and put back in before booting. This is the fist time I have ever replaced a CPU so not sure if I am missing anything.
