i'm trying to trouble-shoot my sister's computer, and would appreciate some help.
when powered up, the computer does not make any sound (beep) at all, and does not output any video to the monitor (not even the BIOS stuff).
the monitor appears to be OK, it displays the "no input signal" message and puts itself into standby mode.
the power supply appears to be OK, the LED on the case turns on, the case fan drawing air in at the fron is working, the fan on the cooling mechnism of the Pentium II slot is spinning. also the CDROM drive is powered and the tray opens and closes.
1. the videocard is dead
(but on second thought, if that were the case then i should still hear the Beeps the mobo makes upon boot, no?)
2. the motherboard is (partially) dead. although it's at least partially working, since it's supplying power to the the cpu-slot cooler fan, to the CDROM drive, the LED.
3. CPU dead?
(haven't thougt about this option till just now - duh
now it seems to me the most obvious possibility...)
i tried pulling the vid card out of its socket, wiping clean the contacts and re-installing, no help.
OK what do you guys think?
any suggestions as to what i should check next?
i can try to replace the videocard with another one (from my computer), but other than that i don't know what else i can try to diagnose the problem. (could that fry my vidcard???)
thaks in advance.
