I've been dealing with this problem for a couple months now, and It's getting really annoying. Ever since I installed my new GPU (Gigabyte GTX960 G1 GAMING), my motherboard boot screen is stuck for a few minutes.
It is also having a few post-beeps, about one in a minute and I can't do anything. I can't open BIOS or anything else. It doesn't respond until a few minutes pass and it continues on startup.
I know why it might be this way, this GPU requires me to plug 2 cables from my power supply and I only have 1. The GPU is still working fine with 1 cable but I assume that this is the reason.
So I'm wondering if this replacing the card\power supply is the only way to fix it or is there something else I can do?
Note: I don't mind waiting for a few minutes while turning the PC on. The real problem is that I can't format my computer.
A real-time clock (RTC) is a battery-powered clock that is included in a microchip in a computer motherboard. This microchip is usually separate from the microprocessor and other chips and is often referred to simply as "the CMOS"
Warning: Do all this after switch OFF your PC.
Did you try with Remove and Reseat the RAM? Try again the CMOS battery and remove your GPU. Do not insert your GPU, reseat your CMOS battery again and switch on the PC!
You risk overdrawing the PSU and damaging it. It can also cause other components to not get enough power or deal with erratic power from an overloaded PSU, so unrelated things may also start to act up. Better quality PSU's are probably going to be more robust than lower quality cheap OEM provided ones.
A video card or other component may be say it needs a 400w power supply, and it probably does only when fully loaded. So you may not experience problems on power on, but only after playing a game or something else that stresses the GPU.
Specific symptoms include:
Display goes black
You can try "burning-in" your card by running a benchmark utility such as FurMark3d or similar for an extended time, giving problems a chance to surface. But don't do it if you know your PSU is underrated. Get a new PSU.
