I have a weird problem with my computer... During morning when I wake up I have a have a hard time opening my computer. When I press the power button nothing happens and after a 1min - 10mins difference it will suddenly open and everything is fine. I have an air-conditioned room and im thinking that the psu is too cool and wont start until it heat up? Is there such an issue with power supplies? In the after noon or evening I dont seem to have issues opening the computer. Any ideas whats wrong with my computer?

Hi , this can be issue with number of things. Lets start with system.
So can u tell us what specified parts is in ur system? That can help.
You can try buy new psu. But mob can be issue too.
So then maybe best thing is build new system. Depending how old system is.
New computer parts are cheap and really fast. They take less wattage too. So it is good idea to build new.

That should be a really good PSU. Or build. all high end parts.

Still it is maybe too good. Is hat PSU a digital one? That can cause issue.
But if you RMA it and there is no problem there is possibility that u end up paying to just check the PSU out.
Maybe best wait if it fails. Then when it stops working then send it back to store or seasonic.
That PSU do have long warranty so there is time to do that. Other things what can cause this is GFX or MoBo.

plz let us know how this issue goes :)  New good PSU price is about 100$ so it is kind expensive test is it PSU issue. http://pcpartpicker.com/part/rosewill-power-supply-ligh...

Some time ago I was looking new PSU and I did bit research. I did end up with non digital PSU.
Digital ones seem to more issues than old non digital ones. Thats why I did buy Rorewill Tachyon.
Gold one is good enough. Not much sense buy 2% more efficiency and pay 100$ more.

For example seasonic 850w broze PSUU one most reliable units that have ever made.
Super Flower makes Rosewill PSUs and they are best reliable units now. Just like Seasonic makes XFX.

Hope you can find way to fix this issue :)  Maybe best ask from seasonic or store where u did buy that PSU.
What to do with it.

The psu is not digital.. I have a feeling it has a hard time opening when it is cold... during afternoon or evening I seem to get no problem opening the computer.... and I dont get any weird noises from the computer or other hardware failure once the computer is on... Everything is great once it turns on. Any idea on whats wrong with my computer during morning when I turn on my ac? Does cold temperature have anything to do with the psu having trouble opening up?

Do you take the pc of the power completely?
Can you look in the bios what the voltage reading is for the motherboard battery? Maybe there is something not good.
