My pc is GQ5090, runs intel celeron D 2.66Ghz, 128MB DDR RAM, and motherboard chipset is SIS661FX. I'd been received pop up message that my virtual memory is low. So I decided to upgrade my RAM to 1GB DDR Ram/400Mhz. I could see a faster processing speed in my pc performance at first. But when I boot up my pc on the second usage, my computer system all of a sudden went into rebooting mode and the problem persisted repeatedly after every 5 minutes. Then I went ahead and reformatting my drive. During the formatting process, it stopped and gave me a message that there is a corrupted cell in my memory, but I went ahead and proceed on with formatting process, and it stopped again and again giving me that same message. So I replaced my new 1GB RAM with the old 128MB RAM, and the formatting process gone smoothly to a completion.
So I have 3 questions that hope to get answer are:
1. How do I determine what maximum capacity of RAM my system need?
2. What speed of Mhz RAM is compatible with my system, 200MHZ, 233MHZ, or 400MHZ?
3. If there is a corrupted cell in RAM, how do I erase it?
Anyone to help answering my question is greatly appreciated!
