Their may be more than one problem. Temps is where I would start.
If the system gets cooked, the other problems won't matter.

hi thanks. I've been hotter than that before. I had another fan which I ditched because I just felt things were getting hot. (just obsession)
Never had an issue with computer resseting itself by then.
Replaced fan about 1 year and a half ago and happy I am with temperature,
I swear my friend, this has nothing to do with temperature.
thanks a lot
Ok well the PSU my friend you can still test with a digital multimeter they are very cheap and you only need to power the machine on and test the leads especially the 24 pin plug and I would be very interested in seeing what the voltage is if any is at pin 8 (grey cable) on that plug.
That is the POWER_GOOD signal pin and if that does not get a 5v signal from the PSU then nothing will start up as it is a safety measure built into the PSU to stop unsafe voltages (over or under) being supplied to the board. Now you can see from my little ditty that the tolerances for the voltage rails are very fine at 5% positive or negative of the required voltage.
I have attached a pic of the 24 pin plug colour coding and it applies to all the other power cables in your machine. The choice is yours to do this and for the sake of doing this (takes a few minutes if that) you could be taking a risk with unsafe voltages.
We have two conflicting points here - your assertion that temperature is fine and your report that you are hitting 75C, which is not fine. Here's a quick and easy way to put the issue to bed though, just run hwinfo64 and keep an eye on the "Distance to TjMAX" area, which I have outlined in a red box. Let us know what the smallest number you see in the minimum column after using the machine for a while.

If you never get closer than say 15C to TjMaxx, then yes your temps are not the issue. In that case I would swap out the power supply if you have not done so already. It was smart to remove that second drive. If your temps are fine after running hwinfo64 and you still shut down with a different power supply, and you've done a full virus scan, and you have no checkmarks in device manager, then my money is on the motherboard, which is impossible to diagnose other than to swap it out....
Yes John but amoretam posted the HW Info could not be run when I asked for the PSU stuff a few posts back. I am really interested to see what those rail volts are because if the CPU is getting a tad over volts maybe it is heating it up unnecessarily
thanks a lot people for the response.
I will follow all indications on wednesday, that is when I have time.
I will try to borrow a multimeter
Thanks again
Ok will await that and I don't know where you are living but really those meters can be bought for very little and are also very handy around the home. You can get them for as little as $5 in some of the dollar type shops or one of the online sites like EBay or Wish.com.
Ok mate have made up a pic for you and if you have nay doubts or queries please ask.
This is a good reference https://en.wikipedia.org/wiki/Power_...unit_(computer) the 24 pin plug is copied from this and there is a pic of a dedicated tester at the bottom of it.
Just remember the voltages are not inherently dangerous themselves only that they are supplied a high current and if you have ever accidentally shorted a car battery then you will know what I mean
