Is it possible to change the PSU output?

Specs: Windows 7, 4Gb
I have a ASUSTeK COMPUTER INC. F2A55-M LK (FM2 ) motherboard with a AMD A8-5600K CPU. The low end voltage in the BIOS is showing 3.7 and flashing red. Its causing my CPU to overheat and switch off when i try to play games.
Is there a way to remedy this or do i need a new PSU?

I dont have my PSU details to hand just yet (im writing this in work) but will supply them later.

"The low end voltage in the BIOS is showing 3.7 and flashing red"

What is the low end voltage? There should be listings for +3.3v, +5v, +12v, the CMOS battery (3v), & possibly others. The safe tolerance is 5% +/- so the limits for the +3.3v rail are 3.135v - 3.465v. Obviously 3.7v is outside the tolerance range so there may be a problem with the PSU.

"Its causing my CPU to overheat and switch off when i try to play games"

The CPU (actually the A8 is an APU) gets its power from the +12v rail so it's unlikely the +3.3v is causing the APU to overheat. If it is overheating, the problem probably has to do with the heatsink/fan installation. What is the APU temperature?

Thanks riider. The heatsink and fan have been replaced yesterday and it was signigicantly cooler (45 degrees when running normal programms). But the temperature shoots up when i try to play games.

Applying the thermal paste correctly is critical to efficient cooling. The A-series uses the "middle dot method". If you did it differently, you might want to remove the heatsink & try again.
