Hi everyone, I've been having a little problem and hopefully someone from the community might be able to help. I own a really basic computer that I've had for years, I don't use it for gaming or anything like that. Mainly sufing the web, really basic none labour intensive tasks. Anyway, I started getting random BSOD problems and the code that came with the shutdown pointed to it being a driver problem. I was using a fairly old driver anyway as I'd have previous problems with BSOD's with the updated versions. After numerous uninstalls and reinstalls of different drivers the problem wasn't going away. Until after one BSOD and restart the screen was completely filled with either green or pink pixels (depending on the background colour). After a little research I came to the conclusion that the graphics card was on it's way out. I should say at this point that the old graphics car was a GeForce 8300 GS. So not wanting to have to upgrade anything but the gpu and also not wanting to spend a great deal of money that really dont have at the moment I started searching for a replacement card for my system. I finally settled on a GeForce GT 610, as it sounded simpler to replace Nvidia for Nvidia in this case and was pretty basic. After researching and installng the new gpu I started up the computer to see wether I'd still have the pixel problem or not. Low and behold they had gone and I thought my troubles were behind me, hahaha how wrong I was... Without any of the Nvidia driver installed (uninstalled in control panel and DriveSweeper used) running on the "Standard VGA Graphics Adapter" I had no problems at all and my cpu usage when idle was fine. I then updated the drivers to the latest version (and numerous other versions throughout the day) and started getting a problem. When the computer attempted to do any task, no matter how basic it would stutter. The loading icon next to the mouse stopping, starting and freeze continuously which it had never really done before. I opened up tast manager to check what was going on and in the 'performance' tab the cpu usage was at 50% in an idle state. After checking processes for all users I couldn't see anything that seemed to be causing the cpu usage to be that high. There were numerous "svchost.exe" open but only as many as there were without the drivers installed, and they weren't using any more memory than normal either. Running HWMonitor showed all my voltages and temperatures to be fine (I've also checked my voltages with a voltage testing machine and they cam back fine). Every time I uninstall the driver and use the standard vga its fine, then as soon as the driver is install I'm getting the lagging and high cpu usage problem. So does anyone think they could possibly shed some light on what might be going wrong? Could it be a clash in the hardware? But obviously I'm so far away from being an expert it's not funny, haha. Any help would be appreciated and sorry for such a long winded essay. Congrats if you managed to read it to the end.
