I Bought my pc 2 years ago and it had been working fine unyil now. It just turned really slow over night, ive tried reinstalling windows and using someone elses hard drive. I currently have 120gb ssd that i use as my hard drive.
Sometimes when i turn on my computer it will start up, mosy of the times it turns on and turns off after around 30 seconds.

Specs: i5-4690k
8gb ram
Asus 970
120gb ssd

The 90 degree CPU temp at startup after being at rest for an extended period is likely to be the problem with the start/stop behavior. If you are getting...

Possibly a random thought. You stated that you have 120Gb SSD as your main drive. In the far not too long ago I 'knew' that keeping the OS drive at or near 50% capacity was fundamental when dealing with a multiple simultaneous processing OS.
I have dealt with machines that do the turn on - turn off behavior. Most of those issues were identified as high CPU temps that were causing self preservation action by the processor.

The 90 degree CPU temp at startup after being at rest for an extended period is likely to be the problem with the start/stop behavior. If you are getting that elevated temp at startup - any load on the CPU will likely push the CPU into shutdown. Take a close look at your CPU cooler - ensure that all the fittings are snug and secure; they may have loosened overtime. If that is not the case - then do not run the machine until you have replaced the CPU cooler - make sure that you use a cleaner to remove any old thermal grease from the CPU - it wouldn't hurt to do the same thing with the contact area on the new cooler either. Be liberal with the new thermal paste - but not extravagant. Arctic Silver has an excellent how to visual on their site.
When you have the CPU opening in the sub 50 degree range - your other issue may go away. Don't hold your breath!
