Batman: Arkham Asylum, Causes my PC to restart, Please help.

[Mr Colt]

So I've just started playing the game for the first time. after about 5-15 mins of game play the game will randomly restart my computer, no blue screen, no error message just black screen, power light goes off for a second then the computer powers back up.
-
Things I've tried:
◘ At first I thought it might be my mild over clocking, so I cut it back then put it right back down to default. *no effect
◘ I've checked my temperatures right after crashing, and they are nice and cool (tho I can't say for sure what the exact temperature is at the time of crash, I have checked after 5mins of game play and well within the normal range)
◘ I have a enermax high end 500w PSU powering a e8500 and 260gtx, I dont think I am power starved, I have been running this rig for a few years now, with no such problems.
◘ I haven't played many games on my rig for a while now, so I booted up a game that I have dropped days of time on at a time, Skyrim, and it runs smoothly with out any issue what so ever, so I think its safe to assume that the problem is with Arkham/Unreal
◘ I have not tried adjusting the graphical settings yet, as the game seems to play as smooth as silk up until the random crash. They are all maxed out except AA at X2, not sure what I would adjust if at all.
◘Updated my drivers for the first time this year to the latest beta.

I dont't know what to try next, or what is the problem.
Please help.

Basic specs:
260gtx, e8500, ASUS P5Q Pro Turbo, 4gb ram, Auzentech prelude sound card
Windows 7 32bit

do you have any other hardware intensive games? Give those a try and see if also fails (skyrim doesn't count). I get the feeling your PSU is failing
if your card is dying it'll just hang or crash at black screen...I doubt it'll reboot the comp

I played Crysis for about 35mins, don't know if it's "high" demanding or not, but no issue playing it.

Check your Event Viewer.

That will tell you what is causing the crash. Or at the very least narrow down the culprits.

[Mr Colt]

That's the thing there is no "event viewer" message after the crash. Windows is like, eh you turned your computer off, w/e.

Played payday2 today on medium settings for about an hour give or take and the shut down occurred.

I had a similar issue back in the day when I was running HD2900PRo's in Crossfire. My PC started restarting because the video cards were dying. I could only run games in Windowed mode. Running full screen crashed the system.

is the game loaded in STEAM ? try to defrag the game files inside of steam.

[Mr Colt]

I'm near positive this is a component failure problem. And I may have fixed it tho, further testing is required.
I swapped around the cables on the modular connections of the PSU, gave the computer a good compressor blow out, and things seem stable thus far. but we'll see.
