Acer apsire 3050, high DPC spikes. System sluggish/unusable

I have an acer apsire 3050-1150. The specs: Amd Sempron 3500 processor, 1.8 ghz, ATI radeon xpress 1100, Windows XP SP3. I keep getting unusually high DPC's, deferred procedure calls, and hardware interrupts. The whole system was running fine until a few days ago. I don't know what happened to it and I have no idea how to fix it. The spikes only happen when I enable the wireless connection and I am connected to the internet, otherwise the computer runs normally. Any help would be GREATLY appreciated.

Can i change my processor? AMD LE-1150 to dualcore or core2duo?


If your using AMD LE-1150 you cant use a dualcore nor a core2duo because the socket of your motherboard is for AMD microprocessor only you can upgrade or change your procs to any AMD AM2 dual core model make sure you check the specs of your motherboard for supported CPU list. you can find that in their website

Hi Paul,

Correct, you have to use the same type, but you can upgrade to a faster CPU.

According to the specs for your computer it can take the following:

AMD Sempron processor 2600+ to 3300+, 333MHz FSB
AMD Athlon processor 2800+ to 3200+, 400MHz FSB

See:

http://support.acer.com/acerpanam/desktop/0000/Acer/AspireT135/AspireT135sp2.shtml

The Athlon's are better...faster Bus. The Sempron is cheaper.

The 2 processors you describe are very similar. The difference between the 2 is that the first one is capable of running 64-bit operating systems and applications. The second one is strictly for 32-bit systems.

The next question will probably be, "What do I have?" Probably a 32-bit system. You can go with the 64-bit CPU and be safe as it can run both. You can see what your old one is by the revision number on the top of the CPU. You can use the following comparison chart to see the differences:

I hope this has been some help. Maybe it has just caused more questions. Just ask.

Thanks for using Fixya.

I have an older Acer Aspire 3000... it recently became to cluttered and when I tried to reformat loading windows 7 ultimate, it stopped saying it couldn't find everything it needed. I'm fairly certain its...


Not all systems are supported by Windows 7. Infact many items that were supported by vista are not supported in windows 7.

looking at your system specs you woudl originally have AMD Mobile Sempron 3000+ / 1.8 GHz , 256mb ram and windows xp home as your original.

this system does not meet the minimum requirements to run Windows 7 Ultimate or Windows 7 at all.

minimum specs for windows 7 are

  • 1 gigahertz (GHz) or faster 32-bit (x86) or 64-bit (x64) processor
  • 1 gigabyte (GB) RAM (32-bit) or 2 GB RAM (64-bit)
  • 16 GB available hard disk space (32-bit) or 20 GB (64-bit)
  • DirectX 9 graphics device with WDDM 1.0 or higher driver

  • i do not recommend a 1ghz system. i would recommend a 2ghz or better with 2GB of memory for a basic version

    Processor upgrade


    Need to look at the motherboard specs along with the processor "Socket". It will usually be a 754 or 939 depending on what your motherboard says. I wouldn't try too fast and set yourself up for disappointment. I would upgrade the RAM before the processor.

    I have put a sempron 3.4 processor in but the system only recognises it as 2ghz ?


    Your processor speed is actually correct AMD calculate the clock speeds differently from Pentium type processors, a 3400+ is a 2.0 GHZ processor, see the list below for speeds Sempron 2500+ 1.40 GHz 800 MHz 128 KB 754 Sempron 2600+ 1.60 GHz 800 MHz 128 KB 754 Sempron 2800+ 1.60 GHz 800 MHz 256 KB 754 Sempron 3000+ 1.80GHz 800 MHz 128 KB 754 Sempron 3100+ 1.80 GHz 800 MHz 256 KB 754 Sempron 3300+ 2 GHz 800 MHz 256 KB 754 Sempron 3400+ 2 GHz 800 MHz 256 KB 754 Don't worry too much about the proceesor not being recognised as long as you know it is running at the correct speed.
