I know this forum usually isn’t about this sort of stuff, but y’all are brilliant, so I figured I’d give it a shot.
A friend came to me complaining about some problems playing games on her computer that started up, according to her, spontaneously about two weeks ago. The product worked fine beforehand and she can’t recall anything major she did to the system in the interim. I can usually help with these sorts of things, but I’m a bit stumped.
Link to the dxDiag
I know it’s an old machine and there’s lots of stuff that looks like it needs upgrading, but like I said, the product worked fine a few weeks ago, so that doesn’t seem the issue.
And a description of the problem:
When playing single or multiplayer 3D games ( sprite games do not trigger this problem in any fashion, nor does the graphical quality of the game ) at seemingly random intervals about once every 2-5 minutes, lasting for about 1-4 minutes the framerate will drop to about 3 and in certain multiplayer games the ping will also shoot upward ( Only noticed in the new Call of Duty, which doesn’t give numbers for ping so I don’t have a solid number for you, but latency will go from green to red in that instance ), before returning to normal ( 25-60 depending on the game )
Now here’s where it gets a bit odd: The problem isn’t tied in any fashion to the intensity of action on screen ( lag looking at a blank wall in an empty building, 26+ framerate in an 8 way firefight, etc. ), nor is it tied by all appearances to the quality of the game’s graphics. The problem has been duplicated in Team Fortress 2, half life 2, world of wacraft, half life 1, call of duty: black ops, mass effect, mass effect 2, fallout 3, fallout new vegas, left 4 dead and sequel, Sam and Max, S.T.A.L.K.E.R., Battlefield, and others.
Even odder there’s apparently a couple peculiar exceptions to this bug, namely in Call of Duty and Team Fortress 2, an empty multiplayer lobby will not generate this scenario, despite single player and normal multiplayer modes both doing so. Apparently there’s no issue in some of the “older” areas in Warcraft either.
As for things I’ve already tried to fix the problem:
-Both rolling back, updating, and uninstalling/reinstalling drivers for sound and video cards. ( as well as updating lots of other misc drivers )
-Exchanging the CPU, graphics card, RAM and motherboard for spare components
-Removing sound card and switching to onboard sound.
-Uninstalling/reinstalling offending games
-defragmentation of both harddrives the user has and their RAM
-cleaning the computer
-adjusting casing to improve ventilation ( the CPU doesn’t appear to ever get hotter than normal though )
So any input would be much appreciated.
