After recently upgrading my case from the stock gateway dx4200 to an NZXT M59
I have been having some issues.
Now when i am in a game the computer will shut off randomly. the issue is that the front power light and the front usb ports still have power. i think it is either a short somewhere or something is overheating.
I have plenty of airflow with 6 120mm fans and all temps are perfectly fine.
I think the issue may be the power supply which is an OCZ 500w ModxStream pro, I also have upgraded to a sapphire 5770 but have also run a 4770 with the same issues
the cpu maxes out at 54 degrees and running prime 95 for an hour it hit 61
so i doubt that is the issue.
i've tried running side panel off even adding fans and nothing seems to help.
today it has been alot worse , I can only play MW2 for about 1 min. and it will shut down. If i just browse the internet or let it sit idle it doesn't seem to have an issue at all.
although when I was switching the MOBO from one case to another i bumped the northbridge heatsink and it came unseated i pushed it back on.
when i first tried to start the computer after the case swap it would turn on for about 5 sec. then shut off. the only way to get it to restrat was to cycle the power supply switch. after some messing around i got it to the point it is at now.
I would check PSU cooling. I have seen my own PC's before just shut down if I didn't have a fan mounted underneath the PSU to create a stream of air to help cool it. So that's the first place I'd look, as OCZ usually makes decent power supply.
So you have a bottom mount PSU then? Glad it's working. Later, if you wanted, you could throw a pci slot cooler fan a slot or two above your power supply to pull the hot air it exhausts out of your system so that it does not stay in there and build up.
Very well could be the power supply going bad. My dad actually just had to RMA an OCZ power supply. Might be worth checking. If you have a microcenter by you, check them out. I picked up a 450 watt BFG Technologies power supply for 30 dollars to sell to a customer just recently. However, it had 2 12v+ rails at 18 amps each. So actually a decent power supply. Not on the level of say a corsair or something like that. However, for 30 bucks, and it's a BFG, you know with BFG you are going to get quality stuff.
In fact, here's this one for 30 bucks, and it's modular to boot.
Might be worth checking out if you are on a budget. Also, keep in mind too, it's possible for just parts of a power supply to be faulty. Which could explain why it goes off after so long, but then you still have power on the front panel.
