I thought my motherboard was dying.
I have an old Lenovo built, IBM branded desktop with 512 megs of memory and a 3 GHz processor. It runs Windows XP Pro, because the bank requires I run a piece of crap software that only speaks Windows. I’ve learned to live with it.
It’s got a Pentium 4, which had heat dissipation problems, which is why I figure the folks at Lenovo installed a gee-whiz thermostat controlled fan that’ll rev-up way high when needed. Normally that hasn’t been necessary, except when I get carried away watching high def movies or spend too much time strolling down memory lane on YouTube.
