Windows explorer using 30 - 35% of the capacity of my CPU

by CTEC19 / August 22, 2015 1:58 PM PDT

Although I'm not quite sure that this comes under this section, windows explorer has been taking up around 30 - 35% of my CPU's processing capacity. it started just after I replaced the broken MSI GD-45 gaming motherboard with the MSI gaming 7 motherboard, whilst doing this I swapped my I5 - 4670 with my brothers I5 - 4670K. minus this problem my system took well to the change informing me that my processor ad changed and directing me to the bios to view any new settings that may have come with the change. After boating up installing the new motherboard drivers and checking everything was fine i added a 600 MHz overclock to the processor which appears to be stable after stress testing it for an hour or so. About a day after the overclock I realized i had this issue. I've run antivirus software, booted in safe mode, in which the problem no longer seemed to persist but when i re-enabled start up items (1 by 1) non seem to cause the problem again until about 30 - 40 minutes into my computer being turned on with all enabled (I should note that this normally occurs as soon as i startup and not after a specific program launches.). short of reinstalling windows, which for me goes XP, upgrade to 7 then upgrade to win 10 i cant think what to do.

I apologies for the very long post but i wanted to be sure none of these little details or a combination of them were responsible for my problem. thank you if you read to the end.

That's one of those persistant issues of moving Windows.

After reading your post, it made me realize I had been having a bit of trouble with my Nvidia drivers, i reinstalled them and now all seems good.

Thank you, will post back if problem persists.
