Cooler Master Elite 460watt is what I am using. This is the first power supply I have ever had from that brand and it seems to be working ok. Had it for about 17 months now with no problems. Normally I have bought Thermaltake brand PSU's, but I ended up getting this one for like $24.99 on a sale with like an instant $15 off 18 months ago because I had their brand heatsinks before and they worked ok and fans didnt crap out on them, so I figured with 4 out of 5 eggs for this that it was worth a try and save some money vs buying Thermaltake for $40+

I installed steam client to my other gaming build which is running Windows 7 64 bit on somewhat similar hardware, and same GPU and it ran flawless for about a day, then same problem struck the day after.
Newer Build Hardware:
Biostar A960D+ AM3+ Motherboard
Athlon II x4 620 2.6Ghz
Crucial Ballistix 8GB DDR3 RAM
ATI Radeon HD 5450 with 1GB RAM Video Card
Windows 7 64-Bit Home Premium on 500GB SATA II HDD
So since this worked for hours the day prior, I figured I would uninstall the game and reinstall the game suspecting corruption maybe the cause and the game is like a 650MB download which is fast.
Uninstalled the game and reinstalled the game and it works again. hmm.... so the install is getting corrupt somehow... So I copied the game folder to another location and when it messes up again I will drop a clean copy of itself overtop if the games location and see if this fixes it. If it is the fix to some sort of corruption then I will just create a quick batch file that will repopulate the games location with the clean files from the known good game state files and use that as the quick fix since obviously this is a file corruption problem from the fact that uninstalling the game that crashes repeatedly and reinstalling it fixes the game for a short while.
No where on Google searches for this have I found anyone pointing the finger to a game file corruption, although someone touched on clearing the AppCache folder in Steam Client which causes all sorts of other problems so vs wiping out that folder and creating a new folder with thet AppCache folder name that was empty, I copied the AppCache folder to another location and then created an empty folder with same name and it caused a whole different crash result. So I placed the AppCache folder and its contents back to get back to the original error, and then uninstalled the game and reinstalled it and surprise the game now works. Closed game, and relaunched it about 5 times just to see if I could get it to break and it didnt break yet. Will give it a day or two and see if the problem reappears as it has and then try the method of copying prior known good game state data overtop of the suspected corrupt install.
Everyone on Google searches seem to be pointing to it having to be run as backwards compatibility as Win 95, WinXP, Win Vista etc on Windows 7 for both 32 and 64 bit versions, as well as the checkbox to run as administrator, as well as changing properties within Steam to get it to work that have no effect on the issue.
I have been able to get the game to run with no problems when not going through this process of backwards compatibility and run as admin etc, and this game will not launch if run on anything less than Windows XP mode under Windows 7 32 or 64 bit as tested on 2 different computers.
As to why the corruption is happening, I have yet to find the file that is the culprit, but I may be able to find it by looking for files that have different date/time stamp between the game install and the copied known good install files. Then I can single out a filename maybe that has some sort of save game state etc that is written to on the closing of the game that may be getting corrupt. Then once I know what file is getting corrupt, instead of copying the entire game overtop of itself, i will try copying that one file over to the game launch location and if that works then hopefully others out there with this same exact problem will benefit from knowing which file to make a copy of and add a simple batch file to their computer as the Temporary which could be a Permanent Bug Fix for a game that has been troubled for a pretty good period of time without Tell Tale Games or Steam putting time into a Bug Fix for it.
Also I didnt get it just working again on the newer build, but also got it to work again on the older gaming build that I first reported this issue on by uninstalling the game and reinstalling it and that worked also with launching and ending game repeatedly with no problems. So I am going to give it time to show back up again and then try repopulating the installation location of Poker Night 2 from a known good state and hopefully that is a fix vs having to uninstall and reinstall the game each time this problem shows up.
