Hi.
I got one desktop PC to fix (Gigabyte motherboard, 4GB RAM, external Graphic Card. I can't recall other specs. It is roughly 3 years old machine).
1. When I turn on PC, the monitor doesn't respond (gets no signal). Monitor is tested and definitely works.
2. All fans are spinning, all LEDs at PC box are lightning, but after running ~1min., it stops for ~5s., runs again for ~1min., stops for ~5s. and all the time like this.
My efforts:
- Unplugged power cable of DVD ROM
- Unplugged one of HDDs
- Pulled external graphic card off
- Unplugged second HDD
- Pulled out RAM memories one by one
After each step PC behaves exactly the same. The only thing I didn't try - other power supply (current one is 400W). I hope it is not faulty Motherboard (without RAM it keeps beeping a healthy sound).
May anyone else has any ideas or encountered similar issue? Thank you very much.
