My system is quite old, so this was expected. The fan on my Asus v9280 went south the other day, so my computer has been out of action for a while now, finally got around to replacing the vid card with a Powercolor X800 a friend kindly donated. It worked like a dream for all of about an hour.
What happened was I took the Asus out, put in the Powercolor. Went into XP via safe mode, removed all existing drivers, then rebooted into XP normally, letting windows find drivers automatically over the Internet. Working great so far.
Drivers found, installed, reboot.
Loaded up Counter-Strike: Source and ran the video stress test. Excellent! Frame rates have more than doubled, even with all settings maxed out.
About an hour later, was burning a CD. Suddenly the OSD shows 'No Signal Detected' and the monitor (BenQ FP222W) goes into sleep mode. Notice that CD was still burning, wasnt sure if it was the computer had hung, or the monitor just lost connection. Wait about 10 minutes and decided the system had hung, pressed hard reset key. Nothing.
Help down the I/O button and powered down. Then when I went to power it back up again, nothing.
Tried all the usual, reseating vid card, unplug power for a minute. Nothing.
Took the video card out, and magic, it booted up. Went into windows. I heard my welcome tone and was able to shut down the computer by pressing *windows key > up > 'u' > enter*
So I m assuming the Powercolor X800 was stopping my PC from even booting up. Weird? I put in the old Asus v9280 in, and booted up first go. Quickly shut down as HSF isnt working.
So... Any ideas? I m guessing its a bad vid card, but why would it break after 1 hour of use? Is it just pure coincidence? Or is there something I m completely missing here? BIOS settings? When the Powercolor is in, computer wont boot at all. Without a video card, or with the old Asus, it will run no worries. Motherboard is Asus P4P800E-Deluxe.
If it doesnt run in another motherboard then the card's likely toast.
See if your friend knows anything about the warranties, and if it's been voided or not. At least I've always had a good tendency to void a video cards warranty
I quickly shut down because the HSF on the Asus v9280 wasnt working...
So basically the computer would boot up with the old vid card, or no vid card at all.
I decided to give the X800 another go when I got home today, before I plugged it in I pulled out the fan connector that was on the vid card, and plugged it back in firmly. I dont know if this was what did it, but it fired up all sweet, and everything is working sweet now, it's been less than 10 minutes since I plugged in the card so I m not holding my breath, but so far so good.
So... I guess it was the fan connector that was loose?
Anyway, I ll see what happens in the next few days, if this card even lasts that long.
