Continuing Problems with Monitor Standby/shutdown During Games of Any Kind

[amswickard]

Little back story. After buying BF3 my computer was going into monitor standby followed by a computer shutdown anywhere from a minute to 10 minutes into gameplay. Upgraded my video card to a 6870 and it continued to do so until I was shown that my pitiful 450w PSU couldn't handle the new card and I got a 600w. Problem went away for Battlefield 3 and have been playing at ultra settings ever since with zero problem.

Flash to getting Skyrim, same problem occurring. Lowered settings from Ultra to about half high half medium with no AA. That seemed to work. (though something seems wrong with being able to play BF3 at ultra yet it can't handle Skyrim at high?) Recently upgraded my motherboard/ram/and CPU considerably. This problem is now reoccurring with Skyrim and even did it once with Lost Planet 2. Still nothing on BF3 however. Recently I loaded up Red Alert 3, and have the same problem.

I'm at a loss as to what could possibly be causing this outside of a bad PSU or video card, but that doesn't explain why BF3 is still working perfectly.

Computer at time of original problem:
-Windows 7 Home Edition 64 bit
-ASUS M4A785-M AMD 785G Socket AM2+ Motherboard
-AMD Athlon II X4 620 2.6Ghz AM3 CPU
-6 Gigs Ram
-Ultra LSP450 450w PSU (changed to ModxStream Pro 600w)
-Radeon HD 6870

Computer now:
-Windows 7 Home Edition 64 bit
-ASRock Z68 Extreme3 Gen3
-i5-2400
-8 Gigs DDR3
-ModxStream Pro 600w
-Radeon HD 6870

Could this really be my PSU dumping on me or did I miscalculate and it's drawing too much power? Outside of hardware issues I see no reason why this setup shouldn't be able to run Skyrim at at least mostly high settings. This little problem has been dogging me since October. I managed to get a recovery error report on the last shutdown.

I could be your vid card but probably the PSU. Under a heavy load it probably fails. I am not sure of the quality of the Mod streams. I would make sure I wans't overheating first, then have your PSU load tested or make sure you get a high quality one, overpowering your computer is not a problem. When ever I build a gaming computer or replace a gaming computers psu I always over power it by 100W and make sure it's a quality one. You get what you pay for and a 600W 35$ psu is just that. Like I said I'd really check the heat first. I missed that blue screen info.. you might want to try a program called who crashed it will translate the dump logs for you and you can see if a driver is crashing.. check heat, run a memory and HDD test from something like the UBCD (google it).
