Greetings, First time poster. I'm quite concerned about some recent developments in my computer.
I built my first computer about two years ago and it was my first experiment with many things such as modular powersources and SLI setup. I've been quite proud of its performance and reliability and overall a great first experience. Here is what i'm working with:
ASUS M2N-SLI Deluxe Motherboard:Newegg.com - ASUS M2N-SLI Deluxe AM2 NVIDIA nForce 570 SLI MCP ATX AMD Motherboard - AMD Motherboards
2GB Corsair ddr2800 RAM
2x EVGA Nvidia 7600GT
SunBeam 550 Watt PS: Newegg.com - Sunbeam NUUO SUNNU550-US-BK 550W ATX12V / EPS12V SLI Certified CrossFire Ready Modular Power Supply - Power Supplies
Power On ATX case( Note has some touch sensitive illuminated buttons, mentioned later ):Power Up Black ATX Mid-Tower Case with Front USB and Audio Ports and Touch-Sensitive Controls TC3G-5018 at TigerDirect.com
Today my roommate calls me at work to tell me that my computer is beeping and wonders if he should turn it off because he noticed the front panel lights were acting peculiar. I ask him in further detail and it sounds like my computer is having some kind of hardware malfunction because it is currently on the bios page with:
*Warning: System BOOT Fail*
Your system last boot fail or POST interrupted
Please enter setup to load default and reboot again.
F1 to continue
DEL to enter Setup
when before I left work the computer was idle in vista. I asked my roommate to hit f1 and it would attempt to start windows error recovery displaying safe mode options but then it would shut off and the "restart" and "shutdown" touch panel buttons on my case flash in unison in a pattern opposite of the "lock" button on my case. The lock button traditionally does not flash for any reason, and I've never seen the power and restart flash in unison.
I asked my roommate to leave it until I got home from work when it stayed in the screen displaying options for safe mode after luckily getting it to that stage. When I got home I saw that it could boot into windows normally and that it did not seem to be a problem with my hard disks. I restarted it and then i'm back to the error message in boot.
After seeing all of this in person I also noted that it constantly beeps. Whenever it beeps, the lock button lights up on the case. Again i've never seen the lock button turn on except when pressing it to lock (stays solid) and unlock (off) the panel.
I decided to clean it out for fear of some dust shorting (which it was dusty) or something over heating which may justify constant beeping. When I plugged it back in, the case lit up normally to show it has power. Whats really strange is I waited a few moments and I noticed the power and reset lights beginning to flash in unison and the case seemed to power on by itself. It was not a successful power-on by any means. There wasnt any display on the monitor but the HDD access light lit up and the case power on sound was made. Now i'm a little hesitant to plug it back in.
With all of these quirky facts laid out, does anyone have any suggestions for troubleshooting? Power supply seems like an obvious choice, but I dont have a secondary PS to test it. Thanks for your help!
