PLEASE HELP; new setup will shutdown in games

[Labrador]

I have a new setup: Abit An8 SLi Fatality, 7800GTX, Athlon64 3500+ etc.. installed it all last night, and it worked great, even tried BF2 for like 10min and smooth as heck all maxxed out.

But tonight playing BF2, the game will just shutdown my system out of no where, just playing the game fine, then 1 second later I hear a click and the whole power shuts down ? I have played BF2 tonight for like 4 hours, and this has had happened like 4 times, almost every hour I will be playing and then wammo complete shutdown ?

Only thing I changed today was buy a new better PSU, had a Ultra Power Connect 500watt, but it was not up to date with 24pin and 6pin PCIe cable, so I bought the Antec True2.0 550watt PSU that has gotten rave reviews.

Any ideas would be great, thank

The only wierd thing I can think of, with this new PSU I looked in my case and I think it is installed upside down ? The big psu fan is on top, close to top of case and the cords in the corner ? could that be heating up when playing games for awhile and causing crashes ?

try installing it the other way and see if the problem goes away.

so how can I fix this ? My buddy said that maybe the bios is set to shutdown system when a part overheats ? Where would that be in the bios ? or is my psu overheating and auto shut down the system by itself ?

This only happens after playing 3D games for like 30min straight

It soundslike your PSU is installed upside down. Pull it out and reinstall it.

A few more things to check:
1. HSF on correctly? Try reseating for the fun of it.
2. Thermal paste used? (had a friend forgot once, same guy who suggest AS3 to me the week before)
3. Are fans on your gpu working correctly?

if this is causing it to overheat, yes it could make a difference.

Im having the same problem is the fan on the PSU supposed to be on top or the bottom? Oop's my bad, my fans in the back

The fan on the PSU should be facing down. That is most likely your problem because of overheating.

smart move replacing your ultra with an antec before it fried your parts. as for the PSU fan, yes installing it correctly will most likely solve your problem. its just common sense that the fan should be facing in a useful direction. if that doesnt solve it, try reseating the CPU and HSF, or checking your GPU to make sure thats not overheating...good luck!

to anwser your question plain and simply... yes it is caused by over heating. Your case will overheat faster if you have something other then a aluminium case. Antec sonatas for example are steel cases, so if you have this case then your computer will be more likely to overheat due to the structure of your case. As for the PSU being installed upside down, yes that could also be a factor. If your PSU fan is on the bottom and not on the top like it should be then the ventilation is just rotating the heated air in your case and causing the rise in tempurature. WIth that said take the fallowing advice in hand

1) Aluminium cases are much more efficient for gaming then a steel one (antec sonata)

2) re install your PSU the way it should be..

3) If you have some money you might consider buying some more fans.

Hope this helps you
