Dear Expert,
I have faced a big problem about my desktop computer. Its showing different behavior on different time. When i want to start my CPU and click on power button then CPU start nicely but monitor can not boot up,its power light still biped. Then I turn off my CPU and start again, sometimes monitor boots up but when its show desktop or open explorer or after some time monitor go to off/previous mode. Then if I give some pressure on my casing like make sound by pressing hand on casing then monitor boot up and show a white screen.

Already I have changed my RAM,power supply and installed new instrument but result is same.

How can I solve this issue. Please give me suggestions.

With Thanks,
Salah

Dear Salah

Here is my suggestion. Have you graphic card checked by a qualified technician.

Good luck

Hi Salah

I think, try to change your processor.. If your CPU run in the same way.. My suggestion is change your motherboard..

because they cant supply more power to boot up..and when you switch the power button.. automatically the 1st priority is your ram before the BIOS... so the motherboard is the problem..
