My computer's performance all of a sudden dropped yesterday, and I truly have not been able to find out why. The only dodgy thing I've noticed is that my CPU is tasked to 90-100% now in Task Manager, but the highest CPU-eating process is something called WMIPrvSE that I cannot kill (keeps coming back). Any help would be greatly appreciated.

The sudden drop happened last night while I was playing Mass Effect 2. It runs fine and has run fine for the past few months, but after getting to a certain point in it yesterday the whole laptop started to lag badly. I'm fairly certain the lag hasn't got to do with Mass Effect 2 though, but I'm no expert at this.

The computer is relatively new (2.5 months) so i doubt it is a fan issue. It is not a temperature issue because this lag happens regardless of length of time using the laptop (plus its winter). The lag doesnt render the laptop unusable, i can still open chrome windows/tabs and FL studio and other less taxing programs with only tiny performance hitches but games like ME2 and ME3, Civ 5, all lag unbearably, Sony Vegas Pro is significantly more laggy, and file transfer is noticeably slower. I'd like to be able to do the latter again, so any more suggestions would be appreciated

I've also checked for malware (McAfee) but it reports clean

okay, downloaded SpeedFan, apparently lowest temperature for the CPU was 51 C and max was 79 C. Is this within the normal range for the laptop i have?

no malware detected with the malware program you linked
