Any computer gurus can give me a quick help?
 

I fixed my computer over the last month after it was out of service for 2 years.


Power supply died. I replaced it.


Had random crashes before that, once I replaced the powersupply I diagnosed a bad memory stick which was replaced.


I don't have any issues with the computer now. It doesn't crash anymore and works flawlessly.


But monitoring the task manager I see erratic CPU usage. Up to 80-90%. This picture below all I am doing is watching a youtube video. Like I said I don't notice any issues using the PC but it's old now so maybe this is a warning sign.


BTW the CPU is i5-2500

CRTL+shift+ESC

Bring up task manager.

Sort by CPU usage.
See whats using up the cpu.

Come back with what service is running.

Don't think there are any computer professionals on this forum.

Click "Show Processes from all users" on the bottom left and be sure to view while experiencing high CPU usage.

Are you noticing a noticeable slowdown when it hits 90%? How often is it happening and what are you doing when it spikes? I would run antivirus in safe mode just to be sure personally.

It's noticing the unnoticeable slowdowns that's difficult.:D

That's why you log incidents of >90% usages.

There are no other users. There is not even a guest account on my computer.
I have run Microsoft Security Essentials. Only thing I can think that it spikes when I alt+tab but that sounds silly considering im alt tab from web browser to task manager???
Well I just happened to notice the erratic graph on task manager while I was diagnosing my random crash issue. It still persists after fixing it. I notice occasional studders in a game I play but I thought it was because it was taxing my system. The screen shots I posted is with Firefox open with 5 or 6 tabs. Youtube, gmail, news article, and a couple forums

Apologies, but I just don't have the patience to tackle a response like this over a forum anymore. Good luck.

Sorry I'm not very computer literate that is why I was asking help :( :cry:

There is a button at the bottom of task manger on the left that says "show processes from all users" You are a user, the computer itself is another user, "sorta" It will show more things than what you screen capped.

Also , alt+tab does make the comp spike to 100% for an instant. That's normal.

Spikes to 100% are normal.

Extended periods of 100% aren't unless you are doing something that is pushing the processor. (rendering video, moving large files, ect)

An extended period would be having the processor pegged at 100% for over 30 seconds.

when i have weird windows issues, i swap a replacement hard drive in, install windows, and then slowly migrate my files over to the new OS.

this also explains why my current gaming rig has 6 hard drives.

It's just been a long week. x808 has you covered.

RAID time.
