So sorry for the late response.
PSU- Rosewill Photon 1050w
Age-5 years
Condition- decent
I cleaned out the dust and reseated everything. It ran faster for a couple of hours but this morning it is back to where it was, so I'm not sure what happened.
I looked into reliability manager and there...
Problem: My computer Suddenly slowed down to a crawl, occasionally speeding up for a while before slowing back down. Games i could run before at 60+ fps are now down to 10-15. Web browsers are also much slower.
What I've tried: Complete factory reset, updating drivers, deleting unnecessary...
