Wierd crash and reboot problems

[brian_130]

Hey, first time post, so hopefully I'm in the right place.
Here are my specs:
Windows XP all service packs
Athlon XP 1800
K7S5A mobo (I know it sucks)
512 DDR ram
Radeon 9000 pro vid card
Soundblaster live value
Quantum 20 gig 72 spin hd
Here's the problem: I recieved two pop-up 'memory read errors at address .... while loading a game. My system then rebooted and loaded to windows. I ran Norton and it rebooted again. This time I went in to Bios and noticed the +12 V number jumping up down very quickly, it rebooted again and this time nothing loaded at all. My monitor gives me a message that tells me its not receiving a video signal. (I've tried other monitors, to no avail.) So now, my system will power up, but nothing seems to happen at all. The hd light is constantly on, and the cd lights blink sporadically, but nothing else. I think its either my power supply, my ram or my video card. Could somone maybe verify this before I start buying and replacing things? Please ask if you need more information. Thanks!

It could also be your motherboard. You didn't mention what your PSU is so I can't comment on that, but this doesn't sound like a PSU issue to me. Also, ram hardly ever goes bad in its useful lifetime. I've had ram stop working, but it was bad to begin with. Besides, bad ram would give you some sort of error or beeping I would think.

From your post I gather you don't have another system to use as a tesbed, but I'll say it anyways. Try your video card and ram in another system. Run memtest86 on the ram if it works.

My feeling is that it's a mobo issue right now though.

Thanks for the suggestions, I was able to test everything and it turns out it was my motherboard. I've replaced it and all it well. I guess someone can kill this thread now.

Thanks!
