Despite having installed the latest nVidia drivers, my PC has gotten from bad to worse. Playing games and videos on it shows a choppy image and also seems to have slowed down even in loading programs or webpages.

Is there some software/website available that can check whether it is the CPU or the VGA card which is defectice?

Before I bought a UPS, there were very frequent power outages. Could that have damaged the CPU?

BTW, my PC is less than a year old, and was working quite well before the virus attack/reformat/ installation of updated driver.

Thanks!

You can do a benchmark from most of your hardware, and compare it with other common hardware...

Thanks for the link Monty. CPU seems good. But was surprised to see results for my c: d: f: g: drives. They (c: & d:) are partitions of a 200 GB SATA drive and (f: & g:) are partitions of a 160 GB SATA drive as well. But the values are nowhere close to that of drive h:which is just a 250 GB IDE drive.

Is there a way to configure both my SATA HDDs to run at optimum level? Are there settings in the BIOS?
