I purchased a graphic card and installed in my pc. My processor is Intel Core To Duo with 2gb ram and operating system is winxp. It was working fine but after few month display of the monitor it’s just black out. After that I reinstalled the card but no unique result provide. Hence after facing this problem I decided to check the card through different monitor and it was working fine there was no problem. Without install the card my monitor work fine. Please tell me some one what is wrong with that? 

My problem is about my Dell S2440L monitor. It is causing the computer to crash after few hours of usage. I tried connecting the monitor to multiple desktops and laptops with different versions of Windows and Ubuntu. They all crashed so I searched for the latest drivers for each OS, but it consistently crashing. Are there any other solution aside from getting the latest drivers?

Hello! I just bought a new monitor and they gave me two cables, HDMI and VGA cable. What are these two cables for? What is the difference between HDMI and VGA cable? Can I use both at the same time because I think there is an option to use both simultaneously. Thanks in advance!

Hello! I am a Windows 7 user and I have this question. Is it possible to have more than one display at a single time. I intend to do this by using multiple monitors but is it actually practically possible? I want to play games on one monitor and surf the web on the other. Thanks in advance!

I have an iMac 27” which was on Mavericks and then I installed Mountain Lion OS. Now the iMac gives a black screen yet the screen is powered. Whenever I click on sleep or if the PC goes on sleep mode by itself, it just fails to power up again. When I forcefully press the power button it then sounds like it is working well, but the screen is not showing anything. What could be the problem? Graphics card or Display?

I really don't know what's wrong with my PC. The frame rate of my PC decreases at once or it crashes sometimes with a buzzing sound from the sound system. Due to this, I'm unable to listen to music while working. FPS crashes also when I play simple games like Mario. What may be the cause of this problem? How can I fix this?

So, I really feel pity on the BIOS screen. The words on the BIOS screen seem like the writings from the late 19s. I'm looking forward to changing the screen resolution at the BIOS screen? Is there a way to do so? If yes, how and if no, why? Any suggestions will help.
