What we don't know is whether you changed one low-end crappy powersupply for another low-end crappy cheap powersupply. Nor have you told us any specifications for the system or the powersupplies you are using. That said, your symptoms may be indicative of an overheating issue. You also say you checked the RAM. How exactly did you test this? Have you also done an inspection of the motherboard for any bulging or leaking capacitors. Those can also suffer heating issues.
