Blank Screen when loading Games

[AAtique]

I'm using PPSSPP version 0.9.1 for windows. Whenever I click load and select any ISO, the screen goes black and it shows "Press ESC to open the pause menu".

Nothing happens if I press ESC. The screen remain black if I do nothing. If I try closing the emulator normally, the screen goes white and it stops responding. I've tried using different builds, but the problem persists for all of them. I've used the default settings and did not download any plugin.

My Specs:
Microsoft XP Professional Service Pack 3
Intel Core 2 Duo E7500 2.93 Ghtz Processor
4 GB Ram
Nvidia Geforce 9500 GT

I've tried loading-
Final Fantasy 7 Crisis Core
Fate/Unlimited Codes

Both of them managed to load on my android tab, so I doubt it's a problem with the ISOs.

This is my first post on this forum, so I apologize if it's the wrong place to ask this. Any help will be appreciated. Thanks in advance.
