Problem description:

Just upgraded to a Gigabyte GTX 980 from a GTX 760 and every time I boot I get the following errors:

    Power supply surge detected

    CPU over voltage error

    CPU over temperature error

What's strange is when I put the old GPU back in I'm still seeing the error

The BIOS says that my CPU is 127°C (fan speed is 1400-1500 RPM) and the voltage is this but I can access Windows through the boot menu and the PC seems to function fine (it's what I'm typing this on). HWMonitor puts the CPU at around 35-45°C. This is why I haven't tried removing the CPU fan and reapplying thermal paste, as surely 127°C would cause some serious issues. I've been using this thing for a few hours at this point.

Attempted fixes:

Tried a different plug socket (it was originally plugged into an extension cable, not it's straight into the wall)

Tried disabling ASUS surge protection

Unplugged and reattached pretty much everything on my motherboard and double-checked nothing came out when I installed the GPU (it's a mid-sized case and it's quite a large GPU)

'Updated' the BIOS to the latest one for my CPU. I say 'updated' because it was the same version it was already on

Recent changes:

Updated to Windows 10 but that was over a week and a half ago and today was the first time I saw issues

--

Operating system:

Windows 10 Pro 64-bit

System specs:

    CPU- Intel Core i5-4440 3.1GHz Quad-Core Processor

    Motherboard - Asus H87-PLUS (ATX LGA1150)

    GPU - Gigabyte GeForce GTX 980 WindForce 4096MB GDDR5

    Memory - Kingston HyperX Blu 8GB (2 x 4GB) DDR3-1333

    PSU - Corsair CX 600W 80+ Bronze Certified Semi-Modular ATX (PC Part Picker puts the estimated wattage of my build at 362W)
Location:

UK

I have Googled and read the FAQ:

Yes


Thanks in advance and I hope I can fix this without too spending too much more. Sorry if I added too much information, just wanted to cover all bases.

I'd try taking the GPU out and using onboard video temporarily.

Do you get errors then?

Just checked. Still getting the errors with no GPU plugged in at all

How long had the computer been working okay before this issue started?

How old is the PSU? That Corsair CX line doesn't have the greatest reputation.

About 12 months (when I built it) and the PSU is also 12 months old

I reapplied thermal paste to the CPU yesterday and that hasn't fixed the error message so I'm pretty sure it's the PSU or the motherboard. I might just leave it until I upgrade next since it's doesn't seem to be detrimental to the computer post-boot
