I have a Dell Vostro 1000 laptop that I have had for about 5 years. Recently, I have noticed that when I first turn the computer on it runs great but after letting it sit idle for a while it runs extremely slow, if at all.
The problem was first noticed a couple weeks ago. Initially the computer kept turning off, first when I was doing computer intensive things(using music or video) then when I was just browsing the internet. When the computer would suddenly turn off, it would be as though you turned off a light switch. If I tried to turn it back on, the light would just flash when I hit the power button but not turn on. It was as though it needed to cool down because after 30 secs or so, it would turn back on no problem. After researching, I figured this must mean it overheated and thought the fan or cooling system was bad. So I decided to take the computer apart and inspect the fan, heatsink, and vents. Once opened with the fan out, I saw there was a lot of dust built up so I cleaned it all out and reassembled everything. I also downloaded the program Speedfan to monitor the internal temperature.
After I got everything back up and running, Speedfan was giving me a core temperature between 48 and 58C. I don't know if this is good or not so I got a chill pad but it hasn't made much of a difference. I have noticed that since cleaning out the inside, the computer no longer shuts off on its own. The problem now is that the computer runs extremely slow if left idle for an extended amount of time. Sometimes its so slow that I think its frozen.
I have tried the BIOS diagnostic tool and tested all components but they all test as working. I have tried online scans and Malwarebytes for spyware but they find nothing. I have run CCleaner and Advanced SystemCare and the system still runs the same. I tried looking for the memory dumps from when the computer would shut itself off but none were created. I have run Belarc and attached the results for my system information. I also ran the autoruns and have attached that log as well.
Hopefully someone here can help with this issue because as of now my system is almost unusable.
Thanks in advance!
