Question about Computers & Internet
Hi....I have a Compaq Presario SR1838NX. When I push the power button to turn it on, it flashes green for about 5 seconds and then automatically shuts off. It never completes the power up cycle. It's only 3 years old. Any suggestions? Thank you for any help.
This is a 1,2,3 item. If it is not the power supply, the cpu or motherboard are the next likely culprits. Generally, if the power supply is OK, the pc would have the fans running and you should be able to open the case and check the North Bridge, the large chip on the motherboard near the cpu and the cooler on the cpu itself. If they are both still cold, it is most likely the mother board.
It it were the cpu, it won't post, but you should still be able to feel the heat with the back of your fingers, just to be safe and touch it quickly so you don't get burned.
You can also try to remove the ram and try to reboot, if you get a steady series of beeps, you can add 1 stick at a time and reboot just to try to elimanate ram as a potential problem.
My next step would be to remove all of the other cards and add 1 at a time and reboot after each card, I probably removw the 4 pin connectord from the dvd/cd hard drives also ans add 1 at a time.
I know this sounds like a lot of work, but this is how I troubleshoot pc and telephone systems for the last 25 years.
