Guys I need your help because my pc is driving me nuts... I will try and explain the issue as easy as possible.. Sometimes my pc wont start at all.. When my pc is switched on for a prolonged period of time lets say 24 hrs it starts to freeze... Browser gets unresonspive etc so im forced to hold the power button and shut the pc down.. When I try to switch it on again it simply wont start like no power is going trough.. I tried so many things.. I checked all connections to make sure they are not loose.. Removed and re adjusted the Ram, reconnected all power connecttions whatever I could do in my little knowlege I have tried.. It will then stay like that and then it switches on after some time.. Sometimes it takes an hour sometimes it takes a day.. I sent my PSU for testing and it came back with no fault.. It happend like 10 times already.. Sometimes it happens also when the PC is in sleep mode.. It sleeps and doesnt start.. This is something I cannot understand at all.. My hardware are as follows Motherboard: Sabertooth P67 VGA: Sapphire HD 7950 PSU: Seasonic 80 Gold 750W CPU: i5 Ram: Exceleram 4gb pc3 Windows installed on SSD.. Any ideas or suggestions please?
