Ministry of silly walks
Hi all! Please apologize my poor english...
I'm experiencing a big and strange problem with my video card, but it
could be related to the motherboard (a7v8x). I'll try to the describe it as
precisely as possible.
My system is: amd 2400+, 512 mb ram, geforce4 mx 440; no overclocking since
I'm not a gamer. It worked perfectly since the last two years.
Last week, while I was working, my monitor (a 1-year-old Samsung
Syncmaster) suddenly became black, as in standby mode (green led
flashing)... but the machine continued working normally. After reboot it
remanied black.
I connected a second monitor; it worked for 20 minutes then it shutten down
again as described.
Now I cannot resume the monitors from stanby even if I connect them to
another pc, so they must have been "fried".
I tried with a third old monitor, and it seems to work, but occasionally I
experience one of these problems (that could happen after 5 minutes or
after 3 hours):
- the image disappears and then re-appears in few seconds;
- the image disappears and doesn't come back (but the pc continues
working); after reset, I hear 3 beeps like the machine doesn't recognize my
video card, so I have to remove it form the AGP slot and then plug it in
again;
- pc resets randomly but after reboot screen remains black (I have to turn
it off and wait some minutes)
- the machine (mouse and keyboard) stops responding and the image freezes,
(once happened while I was in BIOS) !!!!
Voltages and temperatures seems to be ok according to Asus Probe; RAM is ok
according to Memtest; refresh rates and resolution are set to standard
values.
It seems a video card fault but I wonder if a bad video card can result in
these symptoms (and could really damage my monitors). Can it be a mobo/agp
slot problem?
It is a random problem too, so it's difficult to identify it.
I'm really stuck since it's the first time I experience something similar,
and I can't test other video cards.
I hope you can help me. Thanks in advance!
