I am new here and need some opinions as to what the heck is going on with my PC. I have an S4300sx Compaq with a shut down problem. It started with the computer randomly shutting down. I took it apart and reseated everything , but it kept on happening It has gotten to the point where it will boot up and run for awhile and now when it shuts down , it will not boot up. It comes on for second then shuts off. If iet it sit for a half hour or so it will start again but does shut back down eventually.Initially I thought it might be the power supply as I know most often these problems can be traced to that. ...it almost seems as if it is overheating. The fans are all working but could the PS be overheating.
I also noticed that the system interrupt controller is no longer recognized...lost the driver??? However I don't think that is the problem. Any one else think it is the power supply or something else ...processor??Motherboard problem (capacitor heating up )??? ...i know sometimes it is tough to lock a problem down to one thing especially with a PC.
It may be your PSU. But first:
-- Have you cleaned the dust from the heatsinks, including the cpu heatsink?
-- Have you reset the cpu heastsink?
You'll need some thermal interface material, like Arctic Silver 5, rubbing alcohol, and coffee filters to remove the old material and clean the cpu and the heatsink.
Just a while ago someone had the same issue as you are. He found out that the CPU fan is not running. After he replaced it, the PC works fine again. Based on his experience, check the CPU fan first. If it's running okay, then you can narrow down the suspicion to the PSU.
While you're at it, enter BIOS and keep an eye on the hardware temperature. Random shut down is usually connected to overheating issue.
Personally, I'd suspect the PSU. But an organized standard troubleshooting procedure won't hurt.
I have a Dell studio 17 laptop. It has been acting up recently and i cannot get it to shut down properly. I click the shut down button and right when it shuts down it automatically restarts afterward. Can someone help me please?
Shutdown Problem (Solved)
First of all,,Thanx for the suggestios. It was the PS indeed!! I put a new one in and the computer does not shutdown anymore.
I ordered a Bestec 250W from a company online for $34.00, they sent me a replacement PS for the Bestec which they claim is an upgrade but it has no name on it and say's output is 165W ...Max 275 but I guess it's ok ..seems to be working altho i may return it for a better one.
Thanx again for the input.
