Hello,

I have had my computer for about a year now. I am having a major issue with my computer. Everytime time I turn on my computer, nothing happens. All the fans, hard drives, video card, dvd, floppy, and cpu power up, but the computer doesnt boot up. My monitor says no signal and turns off. I have to reset the computer and then it boots up and works perfectly fine. I have switched out power supplies, video card, but it still has the same problem. I have also changed the CMOS battery and updated the bios. I have narrowed it down to 2 things. It is eather is a ram or motherboard issue! Do you think it could be the new bios?

Does anybody know what is causing this problem? Anything I can do to fix this? Any tests I can run?


My Computer:

ATI Radeon X1800XT
AMD Athlon 64 3500+
ASUS A8V-E Deluxe

Creative Sound Blaster X-Fi Xtreme 7.1
CORSAIR XMS 2GB RAM (4 x 512MB)
Western Digital Raptor 74GB 10,000 RPM
Western Digital Caviar 250GB 7200 RPM

Pioneer DVD + - DL Burner Black IDE
NEC Black 3.5" Internal Floppy Drive
Thermaltake Tough Power 600W Power Supply
Thermaltake Tsunami Black Aluminum ATX Mid Tower

ViewSonic VX924 Black/Silver 19" LCD Monitor
Logitech Z-2300 200 watts RMS 2.1 Speaker
Logitech MX518 - 1600 dpi Wired Optical Mouse
Logitech Media EliteBlack Wired Keyboard

Hi Subaru41,
Looks like a nice rig, good-quality stuff, just acting up eh?
To test memory, first run 2 x 512MB only (and try each 512 individually, in single-channel.) You can test all 4 sticks, one by one...
Reset all memory timings in BIOS to SPD. Have you been 'pushing' the ticks? 4 x 512MB requires 2T setting; also memory voltage ~2.75V.
Actually, a new mobo is inexpensive - something like a new A8N-E is ~$100 bucks (cheaper than memory, LoL :^)
Good luck,
Regards

No i havent been overclocking my computer, or pushing the ticks on my memory sticks. I will try reseting the memory timing and let you know.

Thanks

I had a similar issue when I was overclocking my RAM, clearing the CMOS did the trick.

I had the same problem with one computer..

Bought an Antex ATX12V tester and found errors on the power supply.

I replaced the power supply and everything was ok again

I have already switched out the power supply and video card with another and it still does it.

have you tried another brand of the power supply ?

I got the info that the Antec supply I had had trouble with some Asus boards and mine version never managed to work with that computer although I got it replaced, had to take another brand...

Well I just barely upgraded my power supply and new video card about 2 weeks ago. I tried going back to my old video card and power supply, but it did the same thing.

i am going to assume the motherboard is going, best thing you can do is buy one from comp usa or somwhere that sells them, test it out if it works keep it, if it does the same thing bring it back as a return. This is how I would do that:

First thing is take out all unneeded hardware this includes pci cards, usb devices etc like printers scanners everything not crucial. Including cd roms as well and any extra hard drives besides the primary.

If you still have this issue then replace the motherboard using either a friends or a spare or buy a new one then return it when your done. If you still have the issue most likely it is the processor.

You will figure it out, not many things to rule out. check out http://ubcd.sourceforge.net/ for a great boot utility disc. check out the system board, ram and whatever else you can find there.
