Recently, I have been experiencing problems when I switch on the computer. Sometimes, the monitor displays the words "no signal" although the CPU is switched on. When i switch on the CPU, the red light glowed for a few seconds, then it dimmed, unlike usual when the red light will keep flashing. I have scanned the computer with BitDefender, but there are no viruses present so I think it is a hardware problem. Someone please guide me in tackling this problem, thank you.

It sounds like a PSU (power supply unit) problem. Do the fans slow down or stop as well?

By the way, a CPU is a Central Processing Unit. I think what you meant is a PC. :thumbsup:

Make sure the monitor cable is firmly attached. If you computer has a separate video card, you can try reseating it

What kind of computer are we working with? Please list make and model and dell service tag if applicable. If it is a custom unit please list the make and model of the motherboard, graphics card, and memory. If you cant find this you can download and run SIW and copy and paste the information under hardware for the motherboard, video, and memory.

If you download Everest Home Edition it will mirror the voltages as seen in the BIOS. Please check the voltages and post them here.

I had the same problem it turned out the graphic card wasn't in the slot right. Make sure it's firmly down.
