open task manager, is your cpu usage choking at high %'s? If so, go to processes and click show processes from all users. this should show if there is one outstanding process causing your issue. If there is, report it back here. If not, we will go further into troubleshooting.

At the bottom it says: Processes: 102 CPU Usage: 100% Physical Memory: 50%
And Where do I look that there is outstanding process? There is just lot of random names and infos like User Name CPU Memory(Private Working Set) Description

that's the page you want to be on. click on the word "CPU". it will filter the names by cpu utilization. Be sure to click the "show processes from all users" at the bottom before you click on CPU. This will show you the Image Name of the highest to lowest processes by CPU utilization. what are the at the top of that list?

It might be a hard drive failure causing your slow pc. If there are no more options then first try reinstalling win7, and then if that doesn't work the next step is to try a new HDD and start fresh from there. If you have an external HDD, test out installing win7 on that drive.

dgen.exe - about 97 CPU
and then others going 00, 01, 02 like that

He has 100% CPU utilization. HDD is the last thing to be considered. It sounds as though a post login application or service is on drugs and causing this issue. When we find out what the name of this thing is, we can delve further.

Right click it and end process. see if it comes back. run this http://gslink.us/tdsskiller its a rootkit finder and what antivirus are you currently using? What this is from what I read is a bit coin miner. so you are infected. by someone running bitcoin mining on your machine most likely. run that tdsskiller and your antivirus.

antivirus - norton
TDSSKiller ran scans but nothing is detected Norton too
1 new Image poped out - System Idli Process - 75 CPU
and rundll32.exe*32 - 25 CPU

Cool do a boot scan with Norton. it should find it and kill it with fire. sys idl is nothing to worry about. and rundll32 isn't either. its all windows stuff. that boot scan should do the trick.

Here this might be a little more effective: https://security.symantec.com/nbrt/npe.aspx?lcid=1033 download and run this. and restart. I hope this catches it...

I donwloaded npe but when i try to run a scan he asks me to restart pc, when i restart it asks me again

 

[Tcinator]

NPE is supposed to restart the machine to do the scan. allow it to do what it wants to. after it restarts, if it finds stuff, it will want to restart again to remove it. at what part is your issue arising?

 

[lukastwz]

maybe you have skype ? bacause i can almost go to this website its so laggy mine is lukastwz
and i could write to you on the phone easilly

I do not have that capability on my work computer. (I am at work) but running that tool should do all you need. possibly starting it in safe mode with networking. There are other more "power user" ways to check this out, but im trying to stay simple for the fourms sake. but if you right click on the dgen.exe you can hop to the file location, just delete the file if you can. Not sure how well that will work but its worth a try.
