Revolt

I disabled it and now the CPU graph is more diverse ranging from even 15% to 60% so I think it's okay .. Hope it doesn't escalates up to 100% again where I can't even use the mouse. Thanks for your help!

That's the problem, it's not about spikes, it's about a constant high CPU usage: Removed: Malware Could it be "normal" for my specs? System Manufacturer Hewlett-PackardSystem Model Compaq Presario CQ61 Notebook PCSystem Type x64-based PCProcessor Pentium(R) Dual-Core CPU T4400 @ 2.20GHz, 2200 Mhz, 2 Core(s), 2 Logical Processor(s)BIOS Version/Date Hewlett-Packard F.20, 13-Oct-09Installed Physical Memory (RAM) 4.00 GBName NVIDIA GeForce G 103MAdapter RAM 512.00 MB (536,870,912 bytes)Driver Version 9.18.13.697 I uploaded another capture again here, if you can't see the problem I give up and try and bare with it, I bothered you enough, sorry.

But the CPU still remains at over 60% all the time, I don't know what's the average but I was told that 60% is very much having opened only Firefox, Chrome, a small editor and Explorer

DPC_Interrupt.etl

I removed it and the CPU still remains at a minimum of around 60%

I just installed it when running the trace run and it was searching the entire C drive, so that's not the problem, it hanged out before installing it too. I have problems with my battery but it didn't make my computer laggy before. It even shows a warning when I boot the PC but I don't have money to buy another one and also I can't see the connection; if I remove it it will solve the high cpu usage? And the NVIDIA driver is up to date, should I uninstall it and install again? I saw it searches every day for updates ..

Here's the etl zip DPC_Interrupt.zip

I followed your steps until some point: i"Now go to the graphs "DPC CPU Usage" or "Interrupt CPU Usage" (depending where you high CPU usage) and select the intervall, make a right click and select "Load Symbols" and next click summary table." I can't find "DPC CPU Usage" nor "Interrupt CPU Usage" graphs, and also the "Load Symbols" menu doesn't shows up when I right click a graph. I downloaded LatencyMon and it showed me different result by running it multiple times including "ndis.sys", "dxgkrnl.sys", "nvlddmkm.sys". I uninstalled and installed both Realtek and Atheros drives but the cpu still stays at 80%-100%. "Look in the dumped text files for µsec values which are over 256µsec."; I looked in the text file and many of them pass over 256µsec and I'm pretty sure this isn't a good thing. I'll attach it since I don't believe it shows up personal information. Especially when it gets to 100% CPU the pc runs very slowly, even the cursor lags and I don't know how to solve it and it p***es me off. Can you please help me? Iulian dpc.txt
