Think it is time to update my PC? Point of no return?

[kiehugh]

Morning all,

My first post so please forgive any schoolboy errors... I dont have time for gaming, but I do like to have a fast/responsive machine that I can use for work etc

Back in 2009, I had the below PC built for my new house, I have certainly got my ROI back 100 times over.

I have upgraded the hard drive when that failed, I have installed more RAM and last year I had to replace the fan as the machine kept over heating.

Over the last few weeks, the PC has been shutting itself down randomly, and will not switch back on until I full power down from the wall.

I think that I have 2 questions:

1- Is this a PSU failure, if it is how do I find out etc. Secondly could the motherboard be failing? I have the temp sensors and that is not showing anything abnormal.

2- If it is a simple fix, at what point to I reach the point of no return? Like all machines there is only so long before you have to stop replacing parts, as the new components just place greater strain and cause greater issues, and go out shopping.

Happy Sunday

Hey Quartz,

My initial thought was that it was overheating. However I have tried to push my system, have multiple videos running, games running, multiple chrome taps, updates running, norton scanning, outlook archiving, you name it I have had it open and I am still in the normal range.

When it has turned off before, there has been occasions when idling, and also yesterday when I literally only had excel open


Hmmm

I will try the air, I would need to buy a new PSU to test. It appear to be random, so would find it difficult to replicate the conditions.

Power cord check, been on for about 2 hours no problem.

If I don get a new PSU then I will be looking at like for like. Just dont want to have the situation where I replace the PSU and then it is something else. How do I know the point of no return? However in the not too distance future I think it is time for a total upgrade
