Hi there, I am having problems with my computer, everything started when I change the CD/DVD drive after I replaced I turned on my pc and it started up then shuts down (first time) second time it made a beep sound turns on for like 4 second the shuts down. thank you for your help
I found the problem, I think when I replace the cd/dvd drive I move the CPU fan brackets, so 2 supports were loose, causing the shut down for preventing CPU overheating. Thanks for the help
When computer beeps and shuts down withiut booting then either the CPU Fan is not working , or the Heatsink is loose and not sitting properly as you have found . Third is the memory . Pull out Memory Module one by one , then switch on comp to find the bad module.
