I'm posting this here because I have windows vista and I have no idea where to post it else..


Good evening,
Since a few days my laptop's gone REAL slow.. Checked for virusses but none were found..

I just had a conversation with someone and he asked for my laptop specs so I gave them, when I looked them up I shocked; it said I had 800 Mhz and not 2000 as it always does.

Does anyone has an idea why this is or how this came to be?

I never changed something hardware related on the laptop.

Most manufacturer's will limit the speed of the processor if it's in Power Saving mode. Did this happen when the computer was running on battery power? If so, it's likely to be normal. Plug the laptop back into the wall and wait a bit for the system to recognize the AC power - then check it again.

No, The laptop was plugged in the wall, it was charging its battery as it always does when its plugged in.

The power save option was turned off as always, so it doesn't go slower if its on battery.

This may be how Windows is set, but there's also (sometimes) power saving stuff set in the BIOS so it'd be advisable to check there.

My BIOS doesn't have a powersave option. And in the BIOS it said my clockspeed was 2.00GHZ.

Something else :

Its dutch but if you open the same screen you can understand what what is.
its supposed to be at 100%, its 40%.




EDIT:

The CPU graph changes with time - so it'll reach 100% for a short period, but won't stay there for long.
If the CPU stays at 100%, then you'll have a bottleneck that'll slow the system down.

My first guess here would be malware - but you've scanned for that.
Beyond that, I'd guess that it was a Windows problem because the BIOS detects the CPU properly.

Have you checked out the instructions at this page: http://www.schoonepc.nl/
I presume it's the same as the English version here ( http://www.optimizingpc.com/ ) - and it may help to narrow down the issue that's occurring here.
I've spoken with the site owner many times - and he's very good with Windows problems and may be able to glean more from your postings than I can.

Here's a link to the Intel specs for your processor: http://processorfinder.intel.com/details.aspx?sSpec=SLB53

On this page ( http://www.intel.com/support/processors/mobile/core2duo/ ) Intel suggests contacting Acer ( http://global.acer.com/ ) before you contact Intel

I'd still say it was a Windows issue since the BIOS detects the speed correctly - but Acer or Intel should be able to verify this.

Have you overclocked this processor at all, or have you had it overheat on you? This is to rule out damage that may have occurred to the processor.
