I have an ECS K7S5A (SiS 735 chipset) motherboard running an athlon 1.4Ghz and using DDR 266 ram. It's been running well for 8 months, but it started acting strangely a week ago. I was using it, same as always and it just cut out, went blank. Tried resetting, but the board wouldn't POST (no beep codes). Tested CPU(ok), swaped everything, stripped it to CPU only, no beeps. Then I took the MB to the shop because I was sure it had failed. The guy said he tried it and it POSTed right away with his configuration, so he flashed the BIOS to an updated one and gave it back.
I tried it, and it POSTed with the same configuration I had before, but I kept getting "Windows Protection Error. You must restart your system". Left it for a day, then it booted fine. After a few hours, the system suddenly reset while I was using it. Now when I restart, I either get a "Windows Protection Error", or the system resets itself while booting. If I shut it off and wait for a while, I can get it to boot, but the problem keeps popping up.
Somethign's wrong, but I'm not sure what, MB, CPU, RAM, power supply, or even heating maybe? Any ideas? Thanks.
