ASUS M4A88TD-V EVO not posting

[madhatter42]

Hello,
I have the mobo mentioned in the title. The ati cat drivers were set to have it go into hibernate mode after being idle for 4 hours. I was surprised this morning to see the computer still online this morning with all the fans blowing etc. Sat down, and moved the mouse and nothing happened. So I tried to restart it, and it did not respond. Ended up pulling the power cable. Upon replugging it did not post... So i thought the video card had become unseated, reseated it and restarted. It did post, and the bios flashed by. Entered the bios, was not in it for more than 10 seconds when it left the bios by itself and went to the next splash screen.. then went back to the bios splash. It looped through that about 3 times then nothing. Now its back to not posting again. Anyone have any similar experiences?

Im having this same/similar problem. only i think mine is a faulty mobo, all my fans are working and i have not added anything to my system.

PSU (750w Thermaltake, CPU (phenom 1100t 6 core 3.3ghz), GPU (radeon saphire hd6950) have all been working for about 7 months no problem.

M4A88TD-V EVO/USB3 mobo just got replaced about 20 days ago and then everything started to crap out. cant boot, crashes in bios and in boot selection menu. ive gone through many event id's to try fix anything i could while it was still able to boot to windows.

Run memtest with no errors on any sticks
Monitored GPU and CPU heat using speedfan.
Hard Drive extended test on speedfan S.M.A.R.T
Done SFC/Scannow and CHKDSK /R
Fresh install of windows 7 home prem 64 bit.
Run CCleaner and Spybot.

Run on one ram stick with same problem in multiple slots.
run on onboard graphics. same problem

going to remove cmos battery tonight and see where i get too.

Reason i had the mobo replaced was because the last one was faulty. (bad ram slot found from extensive memtesting)

Any advice would be well received as im tearing my hair out and ive exhausted my knowledge and need a pro's help.
