Question about Gateway GM5664 Desktop PC
Shuts down for no reason, replaced power supply
Posted by Anonymous on
You can check temps in your BIOS. That'll tell you if it's an overheating issue.
If temps are normal, suspect a problem PSU or even other hardware. My first guess would be overheating though.
You can check for shorts on the board or bad capacitors. But these are pretty classic symptoms of an electrical or overheating problem. Your temperatures aren't indicating overheating, so there's something funky with the electrical/power system.
The fact that it shuts down with a higher performance mode to me would indicate faulty power.
It sort of seems to me that either you have two bad PSUs (unlikely but entirely possible) or you have a motherboard problem. Replacing a power supply is both cheaper and easier than replacing a motherboard. Now, if you get a third PSU and you're still having the same problems it might be time to look at the motherboard and it's components.
and also Swap the power supply for something like this one:
Newegg.com - SeaSonic S12II 620 Bronze 620W ATX12V V2.3 / EPS 12V V2.91 80 PLUS BRONZE Certified Active PFC Power Supply
Newegg.com - CORSAIR Enthusiast Series TX650 V2 650W ATX12V v2.31/ EPS12V v2.92 80 PLUS BRONZE Certified Active PFC High Performance Power Supply
