So when I start the PC there's 1 long beep followed by 4 short beeps. It was running fine just hours ago and I didn't face any issues of this sort.

Now I did try removing and cleaning the ram and the GPU. The CPU fan is also connected to the right header. But none of this is helping!

PC specs:
Asus H510M-E mobo
XPG ADATA 8gb RAM
Asus GeForce GTX 750Ti
WD Green M.2 SSD 240GB
Seagate Barracuda 2TB HDD
Intel Core i3 10105F

Make sure both ends of each RAM stick is fully seated into its respective slot. Also ensure the GPU is fully seated into its slot.

Also, your PSU has a 3 year warranty. When did you buy it?

I have double checked the RAM and the GPU, both are seated fully.

The PSU is like 7-8 years old. Could it be a problem with the PSU?
