Dad's computer locks up at Picture Slideshow screensaver
My dad uses our old TV as his new monitor (16' in length, 27 1/2' wide) on a 260GTX. Often when his computer goes to screensaver which is set as his My Pictures slideshow it locks up and he has to reboot. This has been going on for the longest time. I've checked his DRAM settings in the BIOS to make sure his voltage was where it needed to be, we've tried using other screensavers and it still locks up as well. No viruses or malware on his comp. He's running Windows XP 32 bit Service Pack 3.
After going through every fix I could think of, my next guesses are upgrade his graphics card or upgrade to Windows 7. What do you guys think?
