Hello.
My problem is rather simple (to understand, at least). It looks like both DIMM_A1 and DIMM_A2 memory slots aren't working. BIOS just doesn't start after I plug in RAM. Did somebody have similiar problem and solved it? I already resetted BIOS, it didn't help. It doesn't report any errors by beeping (checked without any RAMs, the speaker is working).

Hi, Is it the same if you start the board outside the case (just to rule out a short)?

Umm, what do you mean by that? English isn't my first language :(

Neither mine. If the board's circuits touch the case then a short might occur. That's why I suggested taking the board and installing it on its box or similar non conducting surface.

Okay, I did what you suggested. Nothing. Doesn't start.

Then I think that it's either a CPU (memory controller) or a board issue. Try reinstalling the CPU. Check it also for bent/broken pins.

Finally it booted! I just hope it's not something like "I will boot just once to get your hopes up". It seems I just had to clean up the surroundings of CPU and reinstall it. Thank you alexoiu. :)

Okay, this has gone beyond ridiculousness. Since I get no love in Systems, I hope mods won't get mad at me if I post it here, where i can actually get help.
I don't know what else to do besides buying whole new rig, for which I have no money.
Recently I have experienced many bluescreens, like:
SYSTEM_SERVICE_EXCEPTION caused by ntoskrnl.exe
BAD_POOL_HEADER caused by ntoskrnl.exe
PFN_LIST_CORRUPT caused by fltmgr.sys, Ntfs.sys, ntoskrnl.exe
and about three restarts. No errors, just as if I pushed reset button. I scanned and found 6 trojans along with some adware, which were cleaned.

My specs:
ASUS M4N68T PRO
AMD Athlon II x3 440 3.0 GHz
ASUS GT240 512 MB GDDR5
2x 1Gb Kingston 1333 MHz DDR3
1x 2Gb Hynix 1333 MHz DDR3
Logic B21 500W
Samsung 500GB
nothing overclocked

The ridiculous thing I mentiond before is that now after reinstalling Windows I cannot even install drivers from original CDs, which are working on this very laptop I write at the moment. It doesn't seem to be DVD-R issue, because it can read CD with software stuff for saving data on DVDs etc. I have heard that Logic PSUs are actually pretty crappy, but I didn't have problems for 2 years. Could it be PSU problem? Voltages all seem to be good: 3.3v is 3.288v, 12v is between 11.988 and 12.131v and 5v is 5.124v but to be honest I can't measure them when bluescreen or restart happens. I don't have this thing to measure it (forgot what it is called in english, sorry ;p). And one more thing, if somebody decides to help - how much power would I need for that rig which I stated before? Less than 300W seem to be too low to me, but I'm not an expert (calculated using http://www.extreme.outervision.com/psucalculatorlite.js...).
Thank you in advance.
