Hello, I have problems with my PC shutting down intermittently, especially soon after startup. I have been advised that it is probably a power problem and to change the PSU. I would be looking at replacing the current 250W model with a 400W. Will this be OK, and will any additional work have to be done?
nothing else need be done other than fitting it. Before you spend out though I suggest you check to see if the fan on the cpu is working. This will also shut you down if the cpu overheats. Sometimes it is intermitant and it runs for a few minutes. Take the side off and look at it.
