Good day everyone here. im asking for help.
I have my desktop pc and its been working fine for about 2 years. then these past few weeks, I have encounter an unfamiliar issue. When I power on the Box Tower, Its working good but the monitor has no signal and when I try to restart the pc it just the same. the monitor is still no signal. Then sometimes it boots normally but after a few minutes the display has gone and it happens the same when i try to restart. Also I tried to add an external Graphics Card its NVIDIA GT610 then Its working fine but after a few minutes it freezes the display and hang. also the keyboard and mouse are unresponsive.
I tried to fix it by:
1.) Cleaned the Mobo slot for Graphics Card(2gb) and RAM(8gb)
2.) checking the cpu, clean and apply thermal paste.
3.) reset na CMOS
4.) replace Vga cable to HDMI
5.) Re-install OS
Please if anyone knows how to fix it Im desperately need your help. This is my only pc for studying. Thank you in Advance.
