For maximum stability, leave hardware acceleration turned off. Although you can increase the hardware acceleration settings higher than None to regain functionality and performance, these settings increase the chance that the issue will occur again. This procedure prevents the display device driver from programming the hardware incorrectly, but you might lose some display functionality and performance. Option 2: Manually decrease Hardware Acceleration for your video adapter
Vista boots fine, completely stable, no problems at all. After trying to log into windows XP about 5-7 times, I decided to try to boot into vista.
If there are no updated drivers at Microsoft Update, you don't know the name of the manufacturer of the video card, and you need more help diagnosing and resolving this problem, contact your computer manufacturer's product support service. IRQLNOTLESSOREQUAL was the problem, but I didnt manage to get any other information. If there are no updated drivers listed at Microsoft Update, and you know the manufacturer of the video card, contact the card manufacturer's product support service for assistance. If there are any drivers listed, you should install them. But when i pop in the dvd of vista and boot, the loading of files will be ok, but afterwards, after loading, the BSOD that says IRQLNOTLESSOREQUAL pops up suddenly. Go to the Microsoft Update website to see if there are any updated drivers for your video card. Hi guys have this very weird and annoying problem happening to me when installing windows vista ultimate 圆4.
