hi guys,i have recently built my own pc from scratch,everything went fine in the building process but i am having problems with my pci express card.It seems to be overheating even though i have bought a huge gaming case with six fans inside and a temp monitoring system built into it for processor vga and hard drive readouts.My specs are....epox 8npa sli n force 4 motherboard,amd sempron 3400+ 64 bit architecture socket 754,albatron geforce 7100 pci express graphics card,1 gig pc 3200 400mhz,550w psu,6 fans 2 rear 2 top 1 side 1 front, i have not overclocked any of the hardware yet but i was trying to push the system to see what it could handle and what temperatures i was running.As a test i played tiger woods 2007 on its highest res with the game graphics set to best quality instead of best performance.it was going fine until the ninth hole then i started getting white lines down the screen,processor temp 28c, hard drive 35c, graphics card 52c.i let it all cool down and then tried generals on a skirmish and put maximum armies on,ten minutes into the game and the vga temp shot up to 53c and then the game cut off telling me my graphics hardware is overheating...please help as i dont think the graphics card should be running that hot and i dont know how to correct the problem...
