My apologies for not having done a search, but I'm stuck in Safe Mode with a 640x480 screen res and no mouse access. I just tab-navigated my way here :b A little backstory, so you guys can understand the problem I'm experiencing: A couple weeks ago, I rebooted my computer (Athlon 1.4Ghz, 256 MB RAM). Well, the screen went blank and my hard drive light stayed on, while the power light blinked. After opening up the box, I realized a capacitor had fallen off the mother board (I'd rather carelessly installed a DVD-ROM drive a few days earlier, which is the likely cause). So, I had to get a new motherboard. After installing it, I tried booting into Windows, only to get a blue screen telling me there was a problem wuith mY IRQ setting. Not being savvy enough to mess with my hardware any further, I called a friend, who set my secondary hard drive as the master and attempted to install windows on it. He eventually got a blue screen msg, though he didn't give me details about it. Anyway, he said perhaps my RAM had been damaged and removed it, installing 128MB of his own, and attempted a new install. This time, it worked. Before leaving, he decided to try my RAM again. It worked. He couldn't quite figure it out, since according to him, RAM either works, or it doesn't. Anyway, I'd been more or less chugging along since last night. I say chugging along because I experienced several random reboots, two of which happened as I tried to download Quicktime. This makes me think perhpas my RAM isn't the problem, but rather my HDs might be damaged. Anyway, I was feeling more confident as the day went on, and decided to install DirectX, WM9, and ACECMP. It all went well until WM9 was installed. The system rebooted itself prior to finishing the install, and locked itself into a constant reboot cycle. I tried reinstalling windows, but booting from the XP CD gave me a blue screen with an error code I couldn't figure out, which was followed by another reboot. The only way to regain control (sort of) of the PC was to enter safe mode. Folks, what could be the problem? As I said earlier, I'm not very savvy when it comes to hardware, but I'm thinking that if I can actually use Windows (in this mode, at least), my RAM can't be at fault. And since most of my random reboots were experienced while downloading or installing software, I'm guessing my hard drives have bad sectors that are causing these reboots. Could this be it? Could formatting both drives, defragmenting them, and making a fresh install be the solution? Please help, I'm lost here, and I really don't want to spend cash on new RAM if I don't need it. ps-- while I'm stuck in safe mode, could anyone help me enable my mouse?
