Video card problem

[CommunismFTW]

For about 1 month now i have a weird problem with my computer. PC specs are core2duo e4500 (2.4ghz), 2gbram ddr2, an asus mobo p5ld2-se and an asus v.card en8600gts silent.

Almost every time when i start it i need to reboot it once (force reboot from the button). When it's being started the first time he gives out 4 weird beeping sounds and just stays like that until restarted. After the manual reboot everything worked normal ... or so i thought.
Yesterday i found out something weird about the problem. I've installed Gpu-Z cause i wanna upgrade my video card and i noticed that my video card pci express slot was running at x1 speed instead of x16. Had no idea that this is related to the problem. Searched google for a good while for some solutions but none of them worked.
Today, my pc started without problems (no need for force restart, it happens to start like this rarely) and starting GPU-Z i noticed the slot running at full x16 speed. I thought maybe that the change to the slot frequency (from bios) fixed it but at next start of computer (with a forced restart) it was back at x1 speed.

So, every time when the pc starts from first try the pci express slot runs normally at x16 speed. When the first start fails and i need to force restart, it works at x1 speed. I don't know if anyone knows what x1 speed does, so ill give a small example: running youtube movies at higher then 480p resolutions effectively crashes the browser, it lags like hell. I have to start task manager and end the process.

Sry for the wall of text, i wanted to be sure that i explained this very well, so maybe i can get help from anyone that encountered this problem before or heard of it. Help please

never happened to me, but i suppose that u probably did not install the drivers correctly?
just a guess

I figured it out, the card is broken.
And for your information, drivers have nothing to do with a faulty start of the computer

i confused with RAM , if RAM aint working properly it does those beep sounds before it starts and bios does not start to execute the orders

about graphic card, i had same problem with beep sounds, my graphic card was burned.. did those beep aswell... but u confused me when u said that after some restarts sometimes it worked and sometimes not. Because to me it just did some beeps and then blue screen
my bad
