Right now I am facing a major problem with hp e-pc C10 Dekstop computer. It is a very old computer running Intel Pentium III processor. The system boots up file and runs proper for about 15 to 45 minutes and the suddenly shuts down. If I try to boot up again, it won’t boot up for at least 10 minutes. Due to this problem I have installed a new CMOS battery. Running Windows XP. I have also installed another cooling fan assuming that it could be temp problem but still no help. Is there any good solution?
