So I woke up the other morning, turned my PC on and it gave me 1 long and 3 short beep. It also showed that I should "Check the signal cable". I found out that this can be caused by the video card, RAM or BIOS right? So I opened up my PC and took the video card out and put it back in, tried rubbing the contacts with some paper (dont know if this is a good idea throught). Nothing happened. So I tried removing RAM's (I got 2 RAM cards by 1GB). Still nothing. I dont want to go any futher with dismanteling my PC because I dont have expierience in this. But I suspect its the video cards fault. Right? And basicaly what Im asking is should I buy a new video card? Should I try something else to fix the problem? Dont know if this is of any help but here goes my video card and motherboard: My video card: GeForce 8600GT My Motherbord: M2N-E SLI ASUS This is the card Im considering getting:http://www.asus.com/Graphics_Cards/NVIDIA_Series/ENGT240DI1GD3A/#specifications So should I risk getting a new video card? Looking forward for quick responses.
