I have a problem with my old PC, but I’m not really sure what’s the problem. It’s a Windows XP Pro with a Intel Pentium IV and 512 MB processor.
I got this PC around 4-5 years ago if I’m not mistaken.
The problem here is that when I start the computer, the CPU seems to be running since the LED at the motherboard is on, the fan is running and so is the power supply. However, the monitor remained black and blank. After 30 seconds, the light that indicates the CPU is on switches off, but the fan and the normal sounds coming from the CPU remains.
My questions are does anyone have any idea what’s the cause? And do you think it is costly to fix it and will it harm the data inside?
On top of that, the day before I had just tried installing Avira and run it to clean my pc. deleted some trojans in it. The next morning, the computer was running perfectly. The problem had started during the night.
