Probable system overheat, now not starting up

post #1 of 4
Thread Starter 
Hi guys...
Yesterday I was playing a bit of BF3. After about an hour my rig simply shut down and didn't start up again.
After having this problem once before, I waited for about half an hour for it to cool down, as I presumed that it was an overheating problem... I really need to get better CPU and case fans.

Well, the system didn't react anymore. I switched off the PSU and let it be overnight, but the next morning it didn't budge either.

Is there any way of at least getting to know what component took irrecoverable damage, if at all? The first time this happened the CPU cores hit 100 degrees Celsius, but were fine after cooling down again... So I'm guessing that this time it would rather be the mainboard...?

I'm not sure what the TJmax is on that Q9650, but I'm going to guess 71C? So you had it hit 100C from playing a game, it shut down and you did nothing to study the problem? Did you do some troubleshooting, see if your thermal paste, heatsink and fans were seated or working properly?

Now this happens again. I'm thinking that your CPU is fried. May have taken the mobo with it.

I'd start by taking everything out of the case. Disconnecting your cooler and see if something is awry. Clean and reapply good thermal paste, reinstall the heatsink/fans and try to reboot.

If that doesn’t work, test with another PSU. If that does not work, time to upgrade.

Thanks for your reply.
As far as I've understood The core temperature differs from the CPU temperature, which has the TjMax of 71 degrees, yes... My motherboard has a shutdown safety set to 70 degrees CPU temp which should have kicked in I would have hoped.

And yes I did reseat the CPU cooler after the first shutdown, applied new thermal paste and did stability tests. All was fine.

After finally doing loads of trials and errors, I found out that it was one of my GPU's that broke down. All the other components are fine and work properly.
