Dave's wife got a "blue screen," and he thought the monitor was the culprit. Leo says the simple and cheapest solution is to swap out the monitor cable first. If the issue persists, he should try updating the drivers. He can create a bootable thumb drive that will allow him to get into the computer without running the hard drive. He can also do it from a CD. His recovery disc will do this as well. Then if it's a driver, booting to a separate OS would tell him a lot. If it's still blue, then he'll know it's a hardware issue.
Simon has issues watching YouTube videos. He gets a green screen. Leo says that the 'Accelerate Video' setting in Windows is enabled and it isn't working well. Leo suggests disabling the acceleration feature and he should make sure he has the latest video drivers installed. He should also update Flash.
Dennis has a computer that crashes whenever he watches videos. Leo says to check for the latest video drivers. Leo also recommends using Google Chrome because it gets updated to the latest Flash drivers automatically. Dennis could also try closing tabs to reduce the memory footprint. He should also make sure that hardware acceleration is turned off. That can often fix the problem.
Frank says his Windows 7 computer display keeps resetting itself and he has a message saying that the Vista driver isn't working. Leo says it sounds like the driver is crashing. Microsoft certifies drivers that work best in Windows and that's the one he really wants. Motherboard drivers often have video card drivers as well.
John's computer shuts down intermittently. Leo says he has a computer that does it and it's proven to be a flaw, and the company is replacing it. Leo says it's usually related to the power supply, or the computer is overheating. This can trigger a reset. The chat room says it can happen when watching YouTube as video playback is challenging. On the software side, he should make sure he has the latest video card drivers. But if that doesn't work, then he'll have to bring it in.
Steve is having trouble with his screen refreshing a lot on his PC after having changed motherboards. Leo says that swapping out a motherboard is a huge change and it means he needs to do a clean reinstall of Windows after formatting the hard drive. Since Steve is using an OEM copy of Windows, it's trying to install the wrong video drivers. Steve should delete all the drivers from the device manager and reboot.
Paul's PC runs Vista and today he booted up and got nothing but a pattern on his screen. Leo says it sounds like either a bad video driver or a failing video card. Leo advises going into safe mode, reinstalling the video driver and reboot. If it comes back, then he's solved the problem. If not, then he should look into replacing the video card.
