EDIT sorry Abydos, my slow typing again!
Hi and welcome to the WTT forums
Sorry to hear of the problems you are experiencing, but hopefully you will get the advice and assistance you need.
Firstly, yes it would be a good idea to post your printing problem in the hardware forum as many experts scan these subforums to identify any questions where their own specialist knowledge can be useful. However before you do so it would be as well to check (if an inkjet)
1 that your ink cartridges are still reasonably full
2 check your printer driver settings, for grayscale/tint%
3 Check that any ink saver programme is correctly configured
4 That you have used the clean print head function
5 you have used the prime print head function
6 tried brand new OEM cartridges (not refilled ones)
If a laser:
1 That your toner is still reasonably full
2 Toner saver settings are disabled
3 Drum and other replacable elements are within their service life
4 Waste toner bottle/container is emptied/replaced
if a dye sub, or specialist printer
then definitely post in the hardware forum!
Finally its a good idea to download the latest printer drivers from the printer manufacturers website, uninstall your old printer driver, reboot and then reinstall your printer driver aand see how you go.
If still no joy then its off to the hardware forum!
Turning to your 100% usage, this could be caused by malware (in which case posting an HJT log for analysis in the HijackThis and Infections Removal forum is advisable) not here in this forum please.
However there might be a more benign cause, such as a scdeduled anti virus scan or protection product update that is taking a lot of your system resources……… a useful way of checking on this by calling up Task Manager (ALT+CTRL+DEL) and clicking on the processes tab acrross the top, this will list the processes that are running and if you click on the column headers first for CPU this will show you what applications are using the most of your CPU cycles ( resources) you may have to click again to sort the processes into an ordered list.
You can use the same technique to check on memory utilisation………if you are not sure what applications are from their name then fire up your favourite search engine and this should give you lots of information.
