|My sister bought new PC & I'm trying to fix her old one so she can use it to check email & light tasks. 20GB hdd was almost full, so got an 80GB one, copied all info using ddrescue, resized the partition & all works fine, EXCEPT it is still very slow. It has 512MB RAM. I've also put in a PCI wireless card to allow her to set the pc up without worrying about wires & that works fine. Have scanned with Malwarebytes, Microsoft Safety Scanner, GMER, TDSS Rootkit killer and maybe others and found a couple of infected files (which were removed), but nothing serious. Used msconfig to stop all unnecessary startup items. Used ccleaner to clear temp & unneeded files. System runs Avast anti-virus which is up to date. Ran chkdsk and sfc. System is still very slow and CPU usage is running consistently near 100%. Further suggestions????|
Almost forgot... I checked the fragmentation of the hdd and it showed almost 30% fragmented, so it is now defragging which will probably take several hours. I'm hoping that helps, but I'm not confident that it will fix the issue.
I've thought of increased temps causing this, but haven't checked that yet. Or, could there be some driver that needs updating? Or, could it still be infected and I just haven't found it yet?
