Akshay Ganesh asks:
I reinstalled Windows 7 on my computer and now the score of my processor in the Windows Performance Index has fallen from 5.5 to 2.9 and my computer is generally slow and not able to handle some software and games. Is there a problem with the processor or cooling I should look for? My CPU is a Core i5 750.

July 5, 2012Did you do a clean install or install over old data? The drivers could be the culprit and may need to be updated or reinstalled.

July 5, 2012The performance index is the lowest score of the component scores generated. In order for us to know the culprit, we need to know what component has the lowest score, not what the score itself is. Most likely, it will be a driver issue, but there are other possible causes depending on if it is memory, video, processor, etc. In your case, it should not be the processor since any i5 should be at least a 5, but a video card with a sub-optimal driver will drop these scores like a rock.

July 5, 2012something wrong with your reinstallation? is it 32 or 64bits?
try to scan windows with DriverEasy for missing driver

you can format the hard drive and reinstall if you wish (first do backup of files).

July 5, 2012you need to reinstall drivers.
Your windows Aero rating must be screwing up.
Also do a fresh install if you hadn’t.

July 6, 2012Hello Akshay!
WEI is notoriously inaccurate for describing a computer’s performance. Core i5 750 is a powerhouse. It should score highly in any benchmark, no matter how synthetic. PassMark scores it at 4298. Quite fast by any standard.
I really like Bruce’s suggestion of focusing on the GPU’s drivers and ha14′s suggestion of using DriverEasy to update device drivers. It’s my suggestion that you use both methods – use DriverEasy to automatically locate, download and install the latest GPU drivers. And if that fails, try updating any other drivers pertaining to graphics. It’s imperative that you: (1) restart the computer after updating each driver, (2) follow the installation directions for each driver.
The main reason I suggest this approach is that there’s a small chance DriverEasy may use drivers that cause system instability – by limiting your focus only to potential causes of problem and through restarting after each installation you reduce the risk.
And if all else fails, just try installing everything that DriverEasy suggests.
Also, be certain to turn on System Restore, if it is not already turned on. It will allow you to use Safe Mode to roll back bad drivers, in case you are unable to boot.
Fisrt of all Install OS and Driver, than Intall An antivirus and scan whole drive.
October 24, 2012During the scanning process if you think it is slow than ealier, please check your
HDD performance by tranfering a file size not less than 1GB, notice carefully time
taken, if you find still slow than the culprit might be your your HDD. Yes I do honour all suggestions given about GPU , reinstalling , HDD determined the speed. So my suggestion is chksk your HDD in onther computer, these might help your prolem. Firmware update is also necessary but with original one suppplied is still best in your case to find out the culprit.
