Many have BAD CAPS. Did you research BAD CAPS and then inspect for such?
Also, if the power supply is overtaxed or old, you'll see this.
Hey I'm Isuru and have a problem that you might help
I have foxconn mars motherboard, It is 3.5 years old now
It has following problems,
1. Some times PC not power on, mobo led bulb works, but not booting
But after 2/3 days its working normally, Once starts it working completely normally, No over heatings, 45-49 C processor temp, 70-72 C while games playing. (71 C normal in Core2Quad Kentsfield cpu)
2. Some times processor identified wrongly as Core2Due, but after restart it shows correctly as Core2Quad.
3. Computer booting and no display, after 4-5 seconds it is restarting and still no disply and keep restarting. But it is works fine when I re-install the battery,VGA or Ram cards until I turn off the PC. When next day same problem continues. (This problem arise when PC is shutdown around 10-12 hrs, boot completely normally otherwise.)
4. Some times take too much time to pass the POST screen.
What are your ideas, please reply
