hello everyone i have an asus motherboard with a pentium 4 3ghz processor, a radeon 9250 graphics card, 512 mb of ddr ram, and two hard drives. the graphics card/ monitor has apparently been playing up recently, power supply to the montior has been getting habitually interrupted and causing crashes, the screen is getting pixel loss following the cursor, and graphics drivers have been disappearing and reappearing with each reboot. after some particularly bad pixel loss goin on, i tried to reboot and the hard drives are no longer being detected. and i cant enter the setup. could all this just be down to bad ventilation? it does seem to get very hot and noisy within a short time of being powered up. also my monitor is old and ****, but can anyone tell me if these problems are likely to be just monitor-related or if the graphics card is causing them? let me know if there's any other info i shouldve provided. nice one.
