Re: 298MB is 98% of 5.89GB Usable RAM?
bring up end task manager, click processors, click the memory tab, show me a screenie.
It sounds like spyware, malewayre bites download and scan and then give a download of an old version of ccleaner, early 2013 release data for ccleaner, run a scan 2x and run a registry scan, fix all issues.
Goto desktop, open my computer, open c drive, open windows, goto folder ''Prefetch'' delete everything inside apart from ''readyboot''
Now restart, press f8, goto safemode, once open, type MSCONFIG, click start up, make sure all the crap you don't need loading at windows is ticked off, resume in safe mode, give it another scan on maleware, and again with ccleaner, now restart the system, hopefully it's all fixed, once this has been done, make a restore point, simply click start, programs, access..., system tools, system restore, create a point.
Everything should work fine now.
