My PC was fine about a month or two ago and could consistently run games like League, Warframe, and HSR above 120 fps (but I typically cap there for personal preference) on medium-high or high settings. Turned her on one day and couldn't get above 5 fps in any of them so they're sorta unplayable right now. Offline games like Dishonored (okay fine it's my only offline game but I'm not gonna download another one just to check) run perfectly fine so I initially thought it was an internet or driver issue but I'm literally two inches from the gateway and have tested speed there and we're above plan. Drivers are all up to date, even clean installed my nvidia driver just in case but the problem remains. Dusted PC several times and checked that all wires were in place. CPU and GPU temps and usage all appear fine, CPU frequency and core voltage are normal. BIOS settings seem fine from what I can tell although admittedly that's not my strongsuit. Checked for malware. Plenty of space available on C drive. VSync doesn't affect the issue and neither does windowed mode/fullscreen. Even opted into a stupid Windows update just in case a previous version messed up. I know my computer is a few years old but I don't see why she'd be fine one day and then suddenly not with no real explanation, and I don't really know what else to try at this point to fix it.
