Recently, my Windows XP has had a lot of weird problems. Blue Screen while copying files, burning CDs (euh, coasters hehe) and in many cases won't even boot. Some "Missing Entry Points in [...].dll" errors were popping up and just trying again sometimes worked. Now I try to reinstall Windows and I always get problems. I tried a fresh install which reformats the partition (I have a 4 Gigs part for Windows itself, 2 Gigs for the swap file and 2 25 Gigs for my progs, docs, games and others) Almost all the time, while copying files, it will say that some files are incorrect, retrying sometimes works but after it finished installing, all the problems I had were still there. Thinking it was my disk (burned copy) I tryed with 2 other different copies and also another drive. I even tried installing Linux (On a spare 27 Gigs HD I have) and I get a similar error during installation. To further test, I tried installing XP on my other computer (The one I'm currently using - put the 27 Gigs instead of the 6 (Which has Linux on it)) and the installation worked fine. So my CD-ROM drives (24x and 40x Burner) are fine, all my Win XP copies (Although not legit ones) are not causing this. I suspect my Motherboard is the problem (Well, the on-board IDE controller) which is a Gigabyte GA-7ZXE with a recently flashed BIOS. A few months ago, I had a weird error while rebooting that caused me to reset all my CMOS settings so I flashed the BIOS. It didn't help (What if it caused all this?) Since I want to recover my credit card from Christmas, I'd like to spend the least amount of money as possible to get my computer up and running again. Should I get a new GA-7ZXE (100$ cdn) as it seems to be the only one that would take a Duron with SDRAM that my local computer store has. Or if it is just asking for trouble to take the same thing, what would be best between a Gigabyte GA-7VAX (145$) or a Asus A7V-333WA (180$) These last 2 would also mean buying DDR Ram which makes it a bit too expensive. Or is there a chance it might be the CPU? Or the Power Supply?
