So my problem is that some of the times (it happens more and more often) when  I try to turn on my laptop, its screen imediately turns to black, white and gray horizontal stripes and there is a continuos beep. I tried to reinstal my windows, but that didn't help..

Probably the graphics adapter is going bad.  Is this what you have:  AMD Radeon HD 7670M

Windows 7-64 bit or something else?
Continuous beep usually means a hardware problem of some kind, but not always.
If you tilt the display back & forth, does the problem clear up?
Reinstall the driver for Intel(R) HD Graphics 3000.  Get it from Dell Support.

I have windows 7-32 bit.
I haven't tried that tilting the display thing, but I'll do that, if the problem continuos.
For now, I reinstaled the Intel driver, I'll see if problem will disapear, thanks for your help:)

I would first re-seat RAM. If you have to modules / memory sticks, remove one and try with another. If you have one, you can borrow another one from a friend or ask in a nearest local computer store.
Alternatively, you can use memtest (http://www.memtest86.com/download.htm), burn it in a USB drive, make it bootable and boot your laptop using the created usb bootable drive. Let it run till it display "100% Pass complete" at the bottom of the screen. If any errors come up, they will be shown on the screen in red color.
If no errors are displayed, then I would move further to checking of the display cable (which connects screen and motherboard).  This problem can also be of the LCD/LED screen going bad.
If all the above tests are good, then as computer_commando said, can be a graphics adapter/chip problem.
