Well, I had an old computer. It was slow but it worked. I ordered some memory for it. When I booted it up after putting in the new memory it came up with a SYSTEM MEMORY error. Wouldn't boot. so, I put in my old memory and worked as usual. I mentioned this to a co-worker. He said he fixes computers, bring it in. so I did. When I returned the next day I asked if he had a chance to look at it. He said, yes, your motherboard is fried. I was in shock. I told him it was working before I brought it in. I shut it down and disconnected it. He just smiled. So I am now without a computer. Desperately need one for difficult child and homework. I am overwhelmed currently with so MANY, MANY repairs and bills. I just cannot go buy another. does anyone have any ideas where they may sell cheap, old, used computers?
