Voltages in motherboard are low right?

Thanks for your help.

Any thoughts ?

Do you have a warranty on the pc?

I do

You might want to use it first in case it turns out to be a hardware issue. Others wise you will void the warranty.

You are right but maybe can you tell me what exactly is the problem here ?
Thanks.

Your temps are in normal range with a stock cooler. Any higher then 70 c would be a problem . It could possibly be the psu. If it was mine I would have it check under the warranty if you continue to have Problems. This way you will get the correct fix.

That is just sad because today I got like 79c and my pc was making a really wierd noise I think it was the fans :/

Then I would use my my warranty. This way you can get it back to working the way it should. Goodluck!!
