Hi, hope someone can help me with this.
I have 640MB of RAM installed on my pc (emachines 220 running XP Home) but when i go to computer properties it says i only have 256mb. I removed the 512mb upgrade that i installed over a year ago and rebooted the pc, checked and it was showing 128mb so i reinstalled the 512mb and removed the 128mb and rebooted the pc and it shows 256mb so i then put both in the pc and rebooted and it still shows 256mb.
I had no problem until recently when i noticed my pc was running slower than normal. My motherboard supports 2gig of Ram so i don't think there's an issue there.
Checked the bios and where it says "extended memory" the number says something like 650000kb. Is this RAM??
I'm getting desperate, hope someone can help.
