i have this pc about 7 yrs. it powers on but no disp. boot beeps, but the fans, hdd, dvd rom works.
my psu is not branded btw. 540w, and the prob occured when i smelled something burned or toased. i just cant tell surelly.
note: i have no vcard, also tried reseating cmos. checked the cpu hsf normal temp
As you know, something burned out (literally).
The most likely suspects are the power supply and the motherboard (a component on the motherboard).
If you can borrow a compatible power supply from someone you can hook it up to test.
If it is not the power supply then you are most likely looking at a new motherboard. And since this is 7 years old there is a good chance you will not find a new replacement.
It could be time for a new (or new used) system.
i found a shops where i can replace the components. so i should bring it to them.
btw my pc specs are
pentium d 920 3.0 ghz
512mb 533mhz ddr2 ram
via p4m800p... mobo
generic psu 540watts
80gb seagate baracuda 7200rpm sata 2
Along with TVeblen's ideas, also check your monitor on another PC to test it. If you have only onboard video I also suspect the board is bad. Look very closely for anything that looks burned or bare copper traces.
