I have a Windows Vista Home Basic (32bit) laptop with Mobile Intel 4 Series Express Chipset. Two days ago, I decided to check and see if I had the latest version of the driver. It turns out I didn't. So I downloaded and installed the newest version, 220.127.116.118. Ever since then, about once every 30 minutes, my screen goes black for a second or two, then comes back on. A bubble comes up in corner saying "Display driver igfx stopped responding and has successfully recovered." This has become very annoying. It NEVER did this until I "upgraded" to the newest driver version. So is there a way to download an older version, or another way to fix this problem?
