Hey guys, i'm no good with computers and seem to carry this same problem with the couple of laptops which i had and am currently having.
i don't know why my CPU usage is always ranging from 25% - 100%, most of the time ranging from 80% - 100%. i only had internet explorer opened and it was still the same. I checked my friends CPU usage and it's all less than 10%! and they had more things running than me! i don't understand why! i just bought this laptop 4 months ago.
this are the specs:
Dell Studio 1558
Intel(R) Core(TM) i7 CPU M 620 @ 2.67GHz
6.00 GB RAM
Windows 7 Home Premium
Ver 1.00 BIOS A04 PARTTBL
ATI Mobility Radeon HD 5470 1GB
I normally use ArchiCAD, AutoCAD and Photoshop, hence why i got this laptop with these specs. but am still so frustrated cause it's still lagging!
all the apps were pre-installed when i got this laptop but there was only 1 hard disk driver (c drive) so a month ago, my friend helped me divide it into 2, apparently it's easier and better for the laptop if u have 2 hard disk drivers? that might be the reason my laptop is acting so hay-wired?
hopefully someone can shed some light and save me for throwing my laptop against the wall! thanksss!! would really appreciate some help!
Use this link to download and run CCleaner.
Just download it and then open/run the file.
Then use the analyse feature and run cleaner.
Then go to registry clean on menu and run that.
Then go to Tools and check startup programs.
Really do not need many startups running.
Google the names of startup programs you are not sure about to see if they
Close the program.
go to Start menu->programs->accessories->system tools->disk defragmenter
run defrag on both hard drives
it will take awhile sometimes an hour or two.
see if that helps.
Please post back if it does.
1 - There's Too much background tasks. Remove them using the normal procedure (close the icons in the taskbars) Or use task manager (in process tab, you can close everything that is not explorer.exe, microsoft in description and your graphic card driver)
Or use msconfig.exe and uncheck alot of unnessary programs in the startup tab
2 - There's an antivirus scanning. Stop the antivirus scan when you are using your programs but re-enable it IMMEDIATLY when you finished using. (second procedure (REALLY NOT RECOMMENDED) Disable live guard on your antivirus, some antivirus takes lots of cpu when its enabled, but WARNING, you may have more virus, bots, worms attacking your computer!
3 - There's an virus that infected your programs. (explanation why it lag : if your program takes 10ms to respond and the virus takes 500ms to respond so your infected program will take 510ms to respond on 1 task!!!! So for drawing for example, it will take 40 tasks for 1 line=20sec!
Run FULL scan (not quick) with an up-to-date antivirus and re-install your programs after the scan.
Open task manager, go to processes, check to see which program is using most of the CPU, then end that process.
hey guys i did all of the things all of you said but it's still lagging! my friend suspects that it might be a virus as well seeing that i didn't update my anti-virus due to university proxy blockage. but i've tried scanning my whole computer with an updated version and still nothing came up :S
things i did:
scan for virus
scan for malware
end unimportant processors
removing background tasks
removing unimportant startup programs
running TuneUp registry cleaner
everything is still lagging! i was thinking of reformatting my laptop but then i'm afraid that the problem might arise again after (and trust me, with me, it will!)... i need to find the problem to ensure that i fix it and avoid it happening again after reformatting!
thanks for your replies! really taught and helped me but still... any other things you think might be of help?
