Since it doesn't start beeping right away, I tend to think it might be a temperature problem. I would have the case open and turn a big fan on it; if it take longer before it starts to beep, then it's confirm a temperature problem. So do that first and see what the result will be.
I recently built a my own PC, but im having a few troubles with it..
Firstly, i'll give you details on my hardware. Everything was bought from www.overclockers.co.uk, except the RAM, Optical Drive and the extra Fan.
Mobo - Asus M4A785TD-M EVO
Processor - AMD Phenom II X2 3.10ghz Dual Core Black Edition Processor (AM3)
Graphics Card - ATi Radeon HD 4650
RAM - 4gb of DDR3 RAM
Hard Drive - Seagate Barracuda 500gb
Optical Drive - Sony DVD burner.
I think thats it all, i installed an extra chasis fan on the front of my case (Coolermaster Elite 335) but i doubt that would cause any problems. Basically, when i try to install an OS, the PC crashes and it has a continuous beep. However, i did get Windows 7 on it, but it did the same whilst running, especially if i was trying to install drivers.
This is the first PC i built, but im 100% sure everything in the correct place, as i sat with all the manuals for several hours double checking everything. I've read that sometimes new motherboards come with an out-of-date BIOS, and that the builder occasionally has to update it? How can i do this? Is there any way of stopping the PC from crashing?
Help much appreciated guys.
