Hello everyone, and thank You for looking. I am Having a very hard problem with my computer. I just got a new Desktop about 3 days ago and I started to build it up. Well...Yesterday I was messing around with the BIOS graphics system. I have a 256mb graphics card, and so i decided to mess around with it and Change the Memory for it to 512 on the settings area in BIOS. Now it doesn't show a picture on the screen, and It doesnt give a booting beep at all, all I here Is the fans. And I tried the CMOS thing, didn't work My specs: Nvidia nForce2 Motherboard 3 DDR2 512mb Sicks GeForce 256mb Graphics Card(Works, the fan on it works) Unknown(working) DVD burner 160 GB Seagate HD MASTER 120 GB Maxtor HD SLAVE _____________________ I don't have a operating system, I have no idea how to add one _____________________ CPU: AMD Athlon XP 2800+

"And I tried the CMOS thing, didn't work". Did you try clearing the CMOS with the computer unplugged or the PSU switched off? That is necessary in order to clear it.

Yep, I did that

"And I tried the CMOS thing, didn't work" Check you mboard manual and make sure you reset it to the proper "normal" or similar situation after you cleared the cmos. The mboard may not boot if you got that wrong. "a 256mb graphics card" People often say that even when they don't actually have a graphics card. Your graphics adapter is not on a "card" unless it is on an actual separate physical card in a mboard slot. If you mean you set the amount of ram used for your built-into-the-mboard - onboard - graphics, setting that to 512mb should not have caused the problem you are having. You are not supposed to set that to more than 1/2 of the ram installed in the ram slots, but since you have 1.5 gb of ram installed that should not be a problem. If you have an actual graphics card in a mboard slot, the ram on the card is used rather than it sharing the ram installed in ram slots, and in almost all cases the onboard video is disabled automatically when you install a video card in a slot, and any settings for the amount of ram shared with onboard video is ignored by the bios. ATX power supplies are always powering ATX mboards in some places even when the computer is not running, as long as the PS is getting live AC power. Did you unplug the computer, or switch off the AC to it, every time your fiddled with connections or components inside your case? If you DID NOT, you may have damaged something, including possibly the power supply. Do that, and make sure all your connections, and all your ram, and cards in slots, are all the way on their connections or in the bottoms of their slots, then restore power and try the computer. If it still won't boot, a damaged power supply will often partially work, fans and hard drives spin, leds come on, yet you get no video and the mboard will not boot all the way. If you can borrow a PS from a working computer and try it with this mboard, do that. What's the capacity (max watts) of the power supply? Bare minumum it should be at least 400 watts, 430 watts if you have an actual graphics card.

I have a physical GC that I can take away from the Motherboard. And I have a 240 V PS I cant find the watts. And I have tested the Power Supply before and It worked.

Reseat all cards, RAM and cables. You may have disturbed something when you cleared the CMOS. Take proper static precautions when going inside the case.

"....I have a 240 V PS" This isn't likely to be moved unless you deliberately moved it, because it's recessed, but it's possible.... If your PS has a 240v/120v slide switch - it's usually a small red rectangle inside a rectangular opening - on the outside of it at the back of the case, make sure it is all the way to the 240 side. "I cant find the watts." I've never seen a power supply that does not have a label on it that states it's model and specs and capacity, but sometimes it's on a side you can't see when it has been installed in the case, and you must remove it from the case to find the label. There are usually 4 screws you must remove on the outside of the case at the back where the PS fan outlet is, and sometimes one or two more screws that fasten the other end of the PS case inside the computer case. Or, if you bought the case and PS new together, look at the bill for the case if you can find it - the wattage should be on that, or at least the model number, which you should be able to look up on the web. " And I have tested the Power Supply before and It worked." That was then. It may not be okay now. If the capacity of the PS is inadequate, it is common for it to work at first, but then it is damaged from being overloaded in a short time. If your mboard has onboard video, try removing the video card and connecting the monitor to the onboard video port, and trying to boot.
