My mom has always complained about her computer being too slow ever since I've installed a couple of my things on here, and I have to admit, it has slowed it down a bit. So my idea of fixing this was uninstalling some software and getting her some new RAM. Uninstalling the software helped, and the new RAM is doing pretty well, except, just about 10 minutes ago, when I tried to boot up, the monitor wouldn't turn on, and it just kept beeping. So I turned it off, went onto my other computer, googled it, couldn't find anything, and when I tried to turn it back on, it worked fine. Any idea what's going on? I looked up my motherboard's page, and it says that: My RAM's supply voltage is 3.3V, could this be the problem? If you think it is, please let me know, and also post on how to adjust my memory settings in the BIOS, and the ramifications of doing so. I'm also new-ish to installing RAM, and I believe I followed to population rules, (slot 1,2,3 are filled, 1 & 3 with 512 mb each). The RAM I bought:. My specs are: MSI P965 Motherboard 1 GB of existing ram (512mb x2), and added another 1GB, link to the ram is above. Intel Pentium D (Duo/Dual core) 3.40 GHz. Running Windows XP Thanks.
