Hi guys, new to the site, looks like a great place here. Am having trouble with my computer so I am hoping to get some insight from the resident experts. I've just started learning about what does what inside this thing, so bear with me please. So I am gaming (BF2, TF2, FSX) with a 2 year old Dell gaming computer. Yes, yes, I know, buying a Dell was a big mistake. But at the time I knew absolutely nothing about this kind of stuff, so building was out of the question. Anyways, here are some quick specs: Intel Core 2 CPU (Dual-Core) email@example.comGHz 2x Kingston 1GB DDR2 NVIDIA GeForce 7900 GS WDC 250GB SATA HD The two main problems I am having are artifacts appearing after an extended amount of time playing (usually after 30mins), and general lagginess on some of the more resource intensive aspects of these games. As far as I can tell, there are a few potential causes. 1. Heat. The GPU idles at 52°C. Running 3DMark06 with ATITools doing a temp log, when the artifacting appeared during the test, the GPU hit 68°C. 2. The CPU? During the GPU testing portions of 3DMark, I was getting 12-24FPS. However, during the CPU tests I was stuck at only 0-1 FPS. Not sure if this is normal or not, or how to fix it. 3. Crappy Dell PSU? It says it puts out a maximum of 375W, which seems low for a gaming rig? I have blown out the computer with compressed air recently which only helped slightly. Thanks in advance for any help.
