Power issues on Asus M5A78L-M/USB3 motherboard


Recommended Posts

Hello guys! Im tottaly new to this forum and dont even know what data would u need to help me.,

My pc is crashing(reboot) ,slowing down on daily basis .Ive checked it with Aida to find out i got warning signs in those sections,CPU Physical Info:Typical Powe,.CPUID Properties:CPU Thermal Design Power, North&South Bridge, SPD also have warning signs. I tried to highlite those "bad" values. Please help me, coz no way i can do it myself.My power supply is some cheap 650W.This pc was custom build by me.

Do i have to get new power supply or isit faulty motherboard? I also atached full report .Sorry about my english.

Those aren't warning signs, just the regular voltage/power/current icon AIDA64 uses. What may cause the stability issues on your system:

1) Incorrect or too agressive memory settings

2) Memory module incompatibility with your motherboard

3) PSU (Power Supply Unit) failure or weakness

4) Motherboard capacitor issues

5) Overheating

Try to run the AIDA64 System Stability Test (AIDA64 / main menu / Tools / System Stability Test), only have the "FPU" subtest enabled, and press the Start button. Watch as the temperatures climb up, let it go for cca. 15-20 minutes, and then check what are the highest values the temperatures reach. CPU and core diode temperatures should be under 70 Celsius, motherboard and hard disk drives should be under 55 Celsius. If during the test your computer restarts, powers off or Windows throws a BSoD, and the temperatures look not-so-high, then it can be any of the first 4 listed issues.

Thanks very much for your replay Fiery!!

I done as u said: Cpu temp went up to 76 degrees shortly after test has begun. Hdd stayed on about 55 degrees. So that looks pretty normal. Would a little higher temp on Cpu could affect perfomance so badly?

For example when im playing my fav game(dont know if i can say title,so i wont) there is fps counter in top left corner.When i start its on about 90-120fps,after few minutes it drops to 15fps!And stays like that.

I have stock fan on that Cpu.

My pc is not overclocked in any shape or form,RAM is compatible with my mobo,i checked it before i bought it.

Again thanks very much for your help!

You may want to try the AIDA64 Logging feature (AIDA64 / main menu / File / Preferences / Hardware Monitoring / Logging) to record your GPU temperatures (so as other temperatures and voltages) into a HTML file while playing games. That may give you an idea on what are the maximum temperatures your video card reaches, and whether it is normal or too high. A slowdown in FPS sounds quite odd, but an overheating video card may explain that...

GPU temperature is fine, but CPU core temperatures look a bit too high. If it's possible, try to improve the cooling of your CPU, or the exhaust ventilation of your system case. The latter should help to lower both the GPU and CPU temperature.
