Hello Just built a new pc and I am having several problems with it.
Firstly I noticed the CPU is hitting over 100C under high load.(at idle it sits around 27C) It takes only a few seconds to reach this temp then crashes or throttles itself.(1.25 V any lower it does not like) Have tried aftermarket coolers and different thermal paste. Also let a professional pc fixer have a go at installing the heatsink and we are both convinced its on fine with an even layer of paste.
So i assumed it was a bad CPU however I am not so sure as there are some other problems I have encountered: Sometimes the USB ports dont work. Sometimes plugging one in breaks the others. Sometimes they all work fine. sometimes plugging in a usb device crashes the pc.
After a crash the machine has to be left for 10 mins or there will be no picture on the screen.
My specs are: i7 4790k CPU
Corsair 650W PSU
Gigabyte z79x gaming GT motherboard
Samsung 250gb SSD
MSI 7700GTX 2gb
some 14cm fans
A blu ray player/dvd burner/.
ASUS dx2 soundcard.
All of the above are brand new. The only old component is a six month old 2Tb hdd that gave no sign of not working well in my old machine.
I have no idea myself just guessing it could be the motherboard?
Thanks John
