Ok so first of all, the issues I'm about to mention are happening on a new computer (arrived less than 2 weeks ago). The parts were picked out by a friend who knows hardware much better than I (I know little to nothing of the subject).
I had some issues with the display (only resolutions available were 800x600 and something else) which were seemingly solved by reinstalling the drivers for my graphics card MSIR7850). I thought I was good, but upon opening any even slightly demanding game, the display would briefly freeze up and I'd get the error, "Display driver AMD driver stopped responding and has successfully recovered."
I asked my aforementioned friend if he knew anything about that. He said to uninstall and reinstall my graphics card drivers. With the help of google, I downloaded a driver sweeper and made sure said drivers were completely uninstalled before reinstalling. Still I got the same error.
My friend then suggested downloading something called memtest, to check if my RAM was bad. There were no problems there.
Finally I searched for a solution myself, and found someone who had success getting rid of this error by adjusting settings in AMD Overdrive (Check "Enable Graphics Overdrive', set 'High Performance GPU clock settings' to 825, set 'High Performance memory clock settings' to 1200, check 'Enable manual fan control' and set that to 60%). This worked, and I had no issues for about a week.
Then suddenly I started the same "Display driver AMD driver" error upon opening the same games I'd gotten that error on previously, and had not gotten once I "fixed" it. Returning to google, the remaining solutions I could find were few and far between. It was suggested that I update the drivers for the motherboard (Biostar H77MU3), so I tried that. Since I hadn't touched the disk that came with my motherboard (I don't usually touch that sort of disk unless the thing it came with doesn't work), I popped that in and started it up. After that did its thing... my computer was suddenly no longer able to connect to the internet. Oh and my display error wasn't fixed either...
From there, first priority shifted to getting back onto the internet (this laptop is old, and often dies seemingly at random). Troubleshooting the network connection says, "The wireless network adapter is experiencing problems." I uninstalled and reinstalled the drivers for the USB adapter (Linksys WUSB100) (grabbed the ones from the Linksys site on this computer and transferred them via a flash drive. That didn't work. I went to the Biostar site and downloaded the most recent drivers for my motherboard and installed them. That didn't work. The adapter itself has not gone bad. I determined this by installing the drivers for it on this laptop, disabling the internal wireless, and plugging in the adapter. I could connect to the internet without issue.
I feel like I'm running out of options, and I'm very frustrated... Any suggestions?
