Zoli Posted September 20, 2006 Posted September 20, 2006 I just tested my rig with a friend's PSU, a 500W one. Nothing changed, still no boot! I tried to boot with one memory stick in the top orange slot, no HD or DVDRW just the graphic card. No luck, still nothing! Share this post Link to post Share on other sites More sharing options...
Zoli Posted September 20, 2006 Posted September 20, 2006 I'm starting to think that probably the bios got messed up because of the undervolting. Share this post Link to post Share on other sites More sharing options...
ganders75 Posted September 20, 2006 Posted September 20, 2006 What model of PSU was the 500W. You'll really have to try one off the recommended list to be certain... RE: BIOS, this is kind of what i was saying... When you boot the system with it undervolted like that, it may have written to the BIOS in such a manner that it has totally messed up and you need a replacement BIOS chip. I don't know if this is your problem - but it sure isn't sounding good... Share this post Link to post Share on other sites More sharing options...
Zoli Posted September 20, 2006 Posted September 20, 2006 But why would it write data in the bios? I didn't save & exit anything in the bios while in undervolt and sure as hell I didn't flash it! Share this post Link to post Share on other sites More sharing options...
ganders75 Posted September 20, 2006 Posted September 20, 2006 It is still accessing the CMOS part of it though - which is updated everytime you boot. This is still a write, no? If your CPU wasn't stable due to undervolting, it's hard to say exactly what this might do... I'm assuming it is basically the same situation as when you're overclocking - you can mess it up so badly that you need a new chip to get back to square one... P.S. You didn't answer the PSU question? Was it reputable (ie. one off the list) - or just a random 500W model? Share this post Link to post Share on other sites More sharing options...
Zoli Posted September 21, 2006 Posted September 21, 2006 The PSU was some random brand, but I still would have expected the board to act a little differently considering that only one stick of RAM was in and a budget video card.

Zoli Posted September 22, 2006 Posted September 22, 2006 Anyway, I went ahead and RMA the board, my retailer was very relaxed about the thing. Now I'm waiting to see what happens, I'm almost certain now that it's a bios corruption. Share this post Link to post Share on other sites More sharing options...
Zoli Posted September 28, 2006 Posted September 28, 2006 Hi guys, I just wanted to get back with the latest news on the subject. I got my board RMA-ed and it was exchanged with another by my retailer. It's probably not a new board cause it's a little dusty on the chipset fan, but it works. As I got home it, I set it up and it booted right away with no problems whatsoever. So.... finally this prooves that it wasn't a PSU problem, but more likely, a bios corruption due to undervolting. Needless to say, I will not atempt undervolting ever again! It's really a stupid thing to do. Share this post Link to post Share on other sites More sharing options...
