It shuts down instantly, with no warning.
OK. I'll get back to you soon with the results.
Sorry about the delay!!
chkdsk took almost 3 hours to complete!!
The same thing is happening. i tried to watch a recording of a soccer game online, and it powered down again.
Yes thats right, like when you shut your PC down, or 'switch off'.
It is a new (1 month old ) Power supply, but te problem was there before i installed this.
What are you thinking now? A crack or short on the motherboard maybe?
