Question about Sony VAIO PCV-RX753 PC Desktop
If the fan sound is very loud, there might be 2 probabilities- 1) you haven't connected it roperly- 2) the fan is losing its life- so its better to replace it as you can get it for lower prices everywhere..!!

Check that the fan is not hitting any wires in side the case.
If not you may have disoriented the fins while cleaning them. Make sure the fins are not hitting the fan body.
If the fan wasn't installed property the CPU temprature should rise fast and your computer might automatically shut down to prevent damage to the CPU. If that is the case, try reinstalling it making sure it's attached well to the CPU. And remember to add some thermal compound to help the heatsink transfer heat.
If none have solved your problem you can buy a new fan for your CPU at any computer store. Make sure it's compatable with your CPU socket type.
I have lately purchased this fan for my quad core CPU and it's 100% silent. You can run it without a fan also. It's a really huge heatsink. I recommend it.

Plug in an external monitor and see if the display shows up on it. It can be any kind of monitor even the old big fat crt monitors as long as it has a vga cable to connect to your computer's vga port. If so that proves your video card is ok. The video will show on most systems when you reboot without you having to do anything. Some systems will require you to hit the FN (Function key) + F1 thru F12. Hold down the FN key then hit the correct key for displaying on the monitor (F1 thru F12). The correct key will normally have CRT/LCD on it or it will have the icon of a display.
If you see no icons by shinning a flash light and the external monitor works, then your screen is bad. If you see no icons by shinning the flash light and nothing shows on the external monitor, then most likely your video card is bad.
