Got a bit of a problem here. Hoping you can help me figure out what exactly it is. This post will be a bit long.
First, I'll give you the specs of my computer. AMD64 3700+ (San DIego), ASUS A8V motherboard, 1.3 Gig PC3200 RAM, 1 80 Gig Maxtor Diamond 7200rpm HD, 1 200 Gig Maxtor Diamond 7200rpm HD, NEC DVD R/RW drive, Sony DVD ROM drive, Elsa Gladiac 6600GT video card, Soundblaster Live! 24bit, 350W PSU, 1 chasis fan, Windows XP Home and Ubuntu dual boot.
Now for the problem: About a month ago I noticed my computer would not come back on after going into hybernation or suspension (whichever one that basically shuts down you computer, but allows you to turn it back on, without all the bootup stuff, with a short push of the power button). The computer would not come back on when I pushed the power button. I would have to hold down the power button and perform a complete system reboot. However, sometimes the computer would not reboot. The HDs would spin, the DVD drives would spin, the fans would come on, but the monitor would stay blank. I would flip the back power switch (the one connected to the PSU) on, off, on, off, on a couple times and it would catch and boot up. This happened a couple times, so I turned off the hypbernation option in Windows.
Now about 2 weeks ago, this same scenerio started happening again. This time, though, the machine was not in hybernation, it was running overnight with the screensaver on (the monitor turns itself off after about an hour). Same symptoms as above. The screen wouldn't turn back on and I'd have to beboot. I'd then face the same problem as above.
As of now, I can not get my computer to boot using the front power button. If I hit the front reset button, sometimes I get a beep and then nothing. Hit reset again, beep and nothing, again, beep and nothing, again, boots up.
Also, now instead of waiting unitl night time to crash, the computer will crash/freeze during BIOS bootup, during GRUB, while loading Windows, while loading Ubuntu, while using Windows, or while using Ubuntu.
A friend advised that it might be a video card problem. This distresses me cause I bought the video card less than a year ago. However, I took it out, and put in my old Radeon 9200SE (not a good card). I had the same front power button problems, but initially it seemed to work OK. However, after a while it started experiencing the same problems as above.
That's about it. My questions then are, is this a video card problem? Is it a motherboard problem? Is it something else? How can I troubleshoot this in order to figure out which is the faulty componant?
Thanks for your help. Sorry it was such a long post. Let me know if you need any more info.
