anyway, I have this problem with High CPU Usage, it goes to 80%-100% and eventually to 100% if I run one or two programs like Google Chrome. It began a couple days ago, and a couple days before that I installed some new RAM. I'm pretty sure it's not a virus or any malware, I scanned my computer with AVG 11 Internet Security. I'm running a Latitude D620, and I have another one (#2). When I switch the internal hard drive to the other one (#2) the CPU usage is fine. The High CPU Usage (#1) one has 2.0 GHz and 2.5gb of ram. I recently installed a stick of 2gb ram in one ram slot and couldn't install another one in the other slot because I accidentally stripped the keyboard screws. It worked fine for a couple of days, and then the high CPU usage came. I tried switching back to the normal 1GB it came with but the problem is still there. The other Latitude D620 has 1.66 GHz and 1gb of ram (#2). I'm wondering why it works fine on that one but not on the 2.0 GHz High CPU Usage one, would a reformat on the hard drive work? running Windows 7 Home Premium 32-bit on #1 and XP Pro on #2. I also ran BIOS Diagnostics and stuff but that didn't really help.
#1 - Latitude D620, High CPU Usage, 2.0 GHz, 2.5 gb of RAM (Windows 7 Home Premium) 32-bit
#2 - Latitude D620, CPU Usage fine, 1.66 GHz, 1 gb of RAM (Windows XP Professional)
shorter version: I have a two Latitude D620 laptops, one of them has high CPU Usage. When I switch the hard drive to the other laptop, the CPU Usage is fine. I'm pretty sure it's not a virus then or anything, what's the problem?
thanks, happy halloween
