I noticed my computer was running MUCH slower than usual today, so I did the usual virus check anti-spyware stuff. That all checked out, but on reboot, I'm now missing 256 MB of RAM. My computer had 768 MB of RAM (originally came with 256, I bought a 512 chip about 1.5 years ago).
This is the second time in about a year I've lost a 256 memory console. Is there some problem with mixing 256 and 512 that I don't know about? There's nothing prohibiting it in the book for my motherboard. Everything was running fine (this time) until my computer just rebooted for no good reason. I think I was just on the internet. After that reboot is when everything starting going hinky, so I'm assuming that caused (or maybe was a symptom) of what was going on.
I have some program that came with my motherboard, and the temps have been fine. It also is supposed to warm me if it's about to explode or something, and I haven't gotten one.
Is memory this fragile? Does it go bad just sitting in a computer? Is there anything I can do to see if my memory slot is an evil soul-sucking demon? Or should I just accept it as a fact of computer life and go buy memory tomorrow morning?
Memory can be tempermental. Try cleaning the contacts, sometimes they get dusty and the memory doesn't get recognised. If you have a mate with a similar spec PC, see if the ram will work in their PC. If it is dead, buy another 512.
Check to see if your video card has settings for brightness, contrast, and gamma. If it still looks dark on a known good monitor, then you may want to adjust those settings on your video card to get an acceptable picture.
