Well, I've been a lurker but it is now time to post.

Lately my P5E has begun to have difficulties. If I shut it down and restart it, it usually won't post (This problem is much worse if it has been sitting in the off position overnight. If I have been working on the computer for awhile and just do a restart, it will usually restart just fine). It might get halfway through posting and stop, it sometimes says bad bios checksum, sometimes it won't even send a signal to the monitor (it turns on but the monitor goes into sleep mode and nothing happens), sometimes (rarely) it blue screens. I've tried swapping RAM sticks to no avail. It seems like it is more likely to post and load Vista normally if I have been fiddling with it awhile and the system is warmer (may be just me). Once it actually does post, it works just fine. I can play games, do my work etc without a hitch.

I am not overclocking. The only issue I can even remotely identify is that, in the bios hardware monitor, all the voltages are slightly below spec (the 5.5V rail shows 4.9ish, the 12V rail shows 11.9ish etc) but I dunno if that means my power supply is bad or my supply is overtaxed (I went onto the corsair power supply recommendation and I am over-supplied according to the site).

Any ideas?

My system:
P5E (0702 bios)
Q9300
8GB Ram (2) twin2x4096-6400c5
Corsair 620HX power
(2) Samsung F1 750GB in a Raid 0
(2) Sata optical drives
HD3870 Video
Vista 64

Thanks in advance for any help you can provide.

Is your bios going bad? You may try flashing it (Though, if its giving you problems this may not be the best step as you could lose the board).

I don't know, it just sounds like your board is going bad, you might need to contact Asus about it.
