Probably cause of graphical glitches on new build?

Hi all,

I have recently upgraded my PC to the following:

E8400 @ 3.6Ghz with Noctua HSF
ASUS P5Q-Pro motherboard
4Gb (2x2Gb) Kingston 8500 RAM (The stuff on special offer atm)
Sapphire 4870 1Gb

I am also running on Windows 7 Build 7068.

So far, everything has been great (with the exception of PB kicks in COD4 and BF2), however I had some problems with the Empire Total War demo last night which had me concerned.

The demo booted up fine and I went to the graphics options. Most of the options were on but I ticked a few more (I think they were the options for fog and atmospheric haze or something). I saved changes and the screen loaded again (took about 10 seconds). When it came back I had loads of graphics glitches which to me looked like the card was dying. There was no distorted colour but it just looked really odd.

I quit the game, loaded back up, and now everything was just black, I could hear the menus clicking as rolled the mouse around but I couldn't see anything.

I went to the CCC and changed an option on the 3D section which I had moved to 'Better Quality' (or something similar), and I moved this back to the default of 'Balanced' (or something similar).

I booted again and even with the extra options on the game loaded and played very well.

Also, in BF2 I get no issues. However I loaded Project Reality and got major errors, with models and textures being invisible, helicopters were all purple and stuff. I have yet to try it again since changing the above setting in the CCC.

Anyway, could this possibly be that my GPU is underpowered as I only have a 580w Hiper Type-R PSU?

Or could the GFX card be screwed?

Or could it just be because I am on a beta OS?

Thanks and sorry for the long post.
 
I haven't checked the temps but I will check tonight. Would lack of power result in low or high temps?

I am not OC'ing the GPU although I did notice in the CCC that ATI Overdrive seems to be on by default - it was ticked, but greyed out.

I have since disabled this.
 
I don't know for sure but I guess the card would have to be working harder if it didn't have enough power - or was on the limit, so I would assume that this would result in temps rising. However, I thought that it would have given a BSOD if underpowered, not just artefacts.

It is possible that your PSU is underpowered, depends on how old it is I guess - could be the capacitors have aged to a point where they are starting to reach breaking point.

Perhaps try dialling down your CPU o/c & removing any unnecessary external USB devices whilst gaming?

I'm sure someone will correct me though!
Good luck.
