If your system is a Brand name, then we need to know the Brand and model number. If the Operating system or hardware has been upgraded, then we'll need to know this. If it is custom built, then we'll need more information such as, Motherboard manufacturer and model number, processor, amount of memory and type of memory, video card/s are installed network adapter, Operating system. Just pretty much the basics so we know what we're dealing with, otherwise we won't be able to help you. | Report abuse Ask the community Publish Tom's Hardware>Forum>Motherboards>Help> Related ressources: ForumStrange Boot situation on Z77 ForumA7v400 audio driver for windows 7 help ForumDDR3 Tri-Channel Help ForumHelp needed please ForumI need to understand PCIe bandwidth negotiation, please help ForumNew build and need help with Bios settings (ASUS M4A79XTD) ForumHelp, i get nothing after 1 or 2 keystrokes ForumExpert help needed please :-) ForumGeneral Memory Question-Need help!
