Hello
Today in the morning I did a full clean up to my PC I removed all parts that I can from the case and when I poot every thing back and I turn it on it keeps booting on the monitor it saying "HDMI no signal detected "
My PC is pretty loud but when it boots it is quiet .( I checked every fan is working ) OK so she I turn it on its working for 10 seconds and then turn it self off and then again and again

Specs:
Intel i5-3570k
Radeon hd7950
Sad 120gb
HDD 500gb
MSI z77-g43


Tnx for any help
 
i suspect it's a problem with how you put paste back on the cpu... sounds like it overheats and shuts itself down in an effort to not overheat. make sure the cpu fan (and fans) are spinning for those 10 seconds and that the cpu cooler/fan are properly fixed on the cpu.
