FPS drops, slow computer.

[Entus]

So, I'm geting pretty common problem with low FPS and slow system working.

These are my specs:
NVIDIA GeForce GTX 650 Ti
Intel Core Duo E7500 2.03GHz
Western Digital WD Blue WD5000AAK
64-bit Windows 7 Ultimate
4GB RAM

A month ago I bought GTX 650 Ti (replaced my 9500 GT one) so by FPS would get higher in games, since it was really fustraiting to play. However, FPS didn't got any better (I was experiencing 30 FPS in LoL/WoW/CoD4 and I still am). Does anyone has any kind of clue why I'm not getting so low preformance?

Also at a recent LAN party (about 3 weeks ago), some idiot "accidently" pushed my computero ff the edge of table. Computer was working at that moment, but after about 3 days, system was kinda getting laggy, and it got worse (I could barley watch videos on youtube).

Sounds like possibly a PSU going bad, what PSU do you have

When your computer got knocked off the table, it's possible your CPU heatsink got knocked loose, and now you're overheating, which may account for some of the bad performance you're getting. Open up your computer and make sure the CPU heatsink is secure. If it's not, you'll need to reapply the thermal paste and remount the cooler, assuming the push pins weren't broken when the computer was dropped.

As for your performance issues before that incident, did you do a clean reinstall of your Nvidia drivers when you installed the 650Ti, if you didn't your lack of improved framerates may be the result of a driver conflict from your old card.

The actual reason is, when that guy pushed your computer off the table it most likely damaged your hard drive (when dropped a hard drive usually gets damaged) this accounts for the huge performance dip in simple tasks and follows your story to a tee. It wouldn't be the CPU or the PSU that's for sure (I would think since in simple tasks it's slow and intense tasks it's still fine), if even the simplistic tasks are slow and your computer is still running. I would get that guy who did that and ask for the money for a new hard drive that ain't cool.

PSU: 700W
Costumer in shop said it works like Cortex ones.

CPE? not sure, but will check it out.
However, I still asume that is a HDD problem. I will try to get more details.

Any hell, if I would know Mr. Gaylord's name...

Here are some information about my HDD (used CCleaner)
Can any of you tell me if it's anything wrong with it?
