Computer help (random shutting down)

[N17]

Just some help really, I have played Sim City 3000 UK Edition for ages on my PC with Windows 7. And have been doing for ages. However over the past week so my computer will just shut itself off in terms of i'll be on the game one minute and next, thhat's it just turns itself off. So I then take the disc out and turn the PC on and yes it gets past the POST, then yep it switches itself off. Why?

Full spec and model number of PSU?

As above could be a number of things from dust blocking the heatsink to PSU failure

So theres no indication of a stop error or anything, just "flick", its off?
Let us know a wee bit more N17 so someone here can give you a bit more insight into the issue.

Not to hijack your thread, as this may help you also! But I have had the exact same issue the last few weeks I think.. My PC just randomly shuts down with no errors or anything.. I've checked my Event Logs after and nothing in particular is alarming or tells me what it could be. Sometimes it won't boot back up after, after a minute it might or if I switch the PSU off and re-seat the lead and try again it might work, but that could be because I'm wasting a few minutes doing that anyway so it switches on regardless..

I've not had any other issues with my PC, nothing else PSU related or any GPU issues, etc. I can be web browsing and it happens, watching a video and it happens or in the middle of a game and it happens also. Nothing stressful and no errors are reported after.. Strange!

I've found these in my Event Viewer sometimes before & after it happens:

The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.

Crash dump initialization failed!

Crash dump initialization failed!

My specs are Intel i5 750, 8GB RAM, ATI 6950, 60GB SSD, 1TB HD (2x500GB), OCZ 600w ModXStream.

I think it just wants me to buy a new rig. But I'm holding out for Haswell before I upgrade.
