Solve : CPU running slow. What could be the reasons?? |

Answer» I have a Pentium 4 2.4 GHz PROCESSOR. Recently I upgraded to Windows 7. The CPU slows down when playing HD videos, games and multi-tasking and the computer lags. I cleaned the whole system, replaced the HEAT sink, upgraded RAM. When its idle its at full power but slows down as I open more apps or games (Checked with Intel Processor ID Utility). Other tools too report CPU overheating. The hard drive is fine. I think it may be the CPU fan's fault (Works fine but old). Do you think I should replace it? Many Thanks in advance...How much RAM do you have ? ?What make and model is the computer? If you right click on Computer and select Properties, what is your Windows Experience Index? What component of it has the lowest score? Do you have a video card in an expansion slot or do you have onbooard (on the motherboard) video? Other tools too report CPU overheating.What "tools"? Quote The CPU slows down when playing HD videos, games and multi-tasking ...What games? Keep in mind you have an old system to be running Windows 7 on. I have a similar situation. I am running Windows 7 on a 2.66 GHz Pentium 4, with 4GB of RAM (3.50 GB usable). I have an AGP video card in it; it's a NVidia GeForce 6200 with 256MB of memory. The Windows Experience Index on it is 2.9. I have Windows Aero enabled and that works fairly well. I do not play graphics-intensive games with this computer. As far as multi-tasking goes, I typically have a web browser, email client, and one or more other apps, such as Word, EXCEL, or PDF reader, open, and this generally works fairly well. My PC is a custom-made one with an Intel 945G MoBo, Seagate 320GB HD, 2x1GB RAM. My Windows Experience Index shows 2.7 for the CPU and its the lowest. I don't have a video card. Tools like CPU Clock Utility show 'CPU core overheat' all the time. I never overclocked the CPU. Games such as GTA SA, NFS MW, NFS Carbon, FIFA '10, Mafia 2 ran well in XP but not now due to the slow CPU. As to me multi-tasking goes like playing videos & music, web surfing & making Office presentations.You have a 2.7 WEI (Windows Experience Index) for Processor? Is that right? That seems lower than I would expect. My processor, at 2.66GHz, is not much faster than yours but my WEI for Processor is 3.7. Can you add more RAM? Do you have an AGP slot (for an AGP video card)? You have no PCI Express slots, right? If you run dxdiag, what does it show for amount of memory for Display? What size monitor are you using, and what's it's resolution? Edit: You might try disabling Aero. For info on how, SEE http://answers.microsoft.com/en-us/windows/forum/windows_7-hardware/disable-aero-in-windows-7/e3c1e76b-e820-4040-9eec-39caad9092b8Thanks for the reply. The WEI was not just the same every time. When the processor was fine it showed upto 3.4 but now the lowest is 2.7. I don't have AGP but 2 PCI-e slots and 2 PCI slots. The dxdiag shows it has 128MB of Video Memory. The monitor's resolution is 1366x768. Adding more RAM didn't SOLVE the problem. Disabling Aero only sped it up a little bit.I just ran the WEI again and now it shows the CPU and the 3D Business and Gaming Graphics having the lowest and equal score of 3.3 with no progams running in the background.

The WEI should remain constant unless you've made a hardware change (RAM, video card, etc.) or updated a driver. So, that fluctuation you've reported may be a clue to some problem with your processor or motherboard. I suggest you observe your WEI on a frequent basis for awhile to see how it varies. Normally, I believe you need to re-run the assessment, or re-generate the WEI, to make it re-calculate the scores. It toes not re-calculate by merely opening the Properties panel for Computer. I scanned the WEI again. It remained the same. There is a thing I noticed. One of the wedges of the latching mechanism which holds down the CPU fan to the Mobo is broken, which causes the fan & heat-sink not to attach to the CPU completely. I think the CPU is not completely in contact with the heat-sink, which may cause it to slow down. Do you think this is the cause?

Replacing the fan solved the problem. |
