To the admin: I posted this here because I think my mobo is the fault, but if I'm in err, please feel free to move the post. I searched around for some time trying to figure out whats wrong, but I am out of ideas. Asus A7N8X 3000+ w/ 200 FS bus 1g Corsaid XMS 2-3-2-6 matched run in parallel Asus Geforce FX 5900 Ultra Netgear NG311T Wireless card one 15g IDE drive running only Windows XP pro 2x120g Serial ATA run in striped raid BIOS and all drivers are at the newest versions. Several months ago my aunt asked me too help remove stuff from an old computer, so I pulled out the drive, and attached to mine to remove everything. At the time, I didn't have virus software installed, and after about a week, I realized something was wrong, found the problem and deleted the virus. Since then, though, I have had some major wierd hardware issues. In the Bios, I can not set my CPU speed to anything over what it defaults to when I use the reset jumper. If I change the settings to aggressive, or raise the bus from 100 to 200 (where it should be), then when it boots again I get wierd dancing squigglies all over the screen. I can see through them that Windows is still booting fine, but it's all a colored mess. When I am in windows, I get strange beeping sounds, that cause my computer to freeze for about 2-4 seconds, while some major "think" sounds come from the processor, then a slight click, then everything works again. These happen more frequently when running a game, and happen constantly when trying to run something like 3DMark, and happen whenever I try to use the mouse wheel in Internet Explorer (but not in Netscape, which is what I usually use). Just happened again, man thats driving me nuts. So, now even as I typed this, it seems to me that something is wrong with either my mobo, my cpu, or my vid card. Unfortunately, I have just moved, and don't know anyone, nor have the funds to procure test subjects to rule any of these out. So...has anybody heard of this, or have any suggestions...not looking for a miracle cure, just a direction to keep looking in, until I can try swapping out some parts.
