Hey people! First specs:

Gigabyte GA-X58A-UD3R (Rev. 2001)
Corsair 3x2GB DDR3 1600MHz

Today I was cleaning the insides of my PC, also removing memory sticks and putting them back in, and afterwards my computer won't POST giving 2 short beeps (indicating memory issue?). I've checked I have the memory sticks installed correctly (white sockets, 1/3/5). Everything else seems to be working except the memory; LED, fans, DVD and USB etc. all work. Gives 2 beeps and won't POST even if I have no memory sticks installed. What am I doing wrong or what did I possibly fry?

Tried that, didn't work. If it's not a RAM issue what should I do to find out why it's not POSTing?


I cleaned it by just vacuuming all the dust from the insides, but I also took out the memory sticks and put them back in. I triple-checked that they're seated in the right order. The RAM sticks might have got some static but I think that's pretty unlikely, especially when none of them are working by themselves either.

Tried holding down the "Clr CMOS" button at the back for 5+ seconds, but it doesn't do anything.

Now that I looked more into it there are some MOBO error LEDs on that I don't remember being lit before when I switch the power on. They are (according to manual):
DDR overvoltage LEDs (4 (?) LEDs to the right of the RAM seats), they are from downwards and up: green, yellow, green, yellow. Green indicating slight and yellow indicating moderate overvoltage.
PHASE LEDs (6 LEDs in the upper right corner of the MOBO under the overclock LEDs) indicating CPU loading, from downwards and up, I think it seems like: green, green, yellow, yellow, red, red.

''I cleaned it by just vacuuming ''

that can be a death nail right there that was a bad thing to do.. you need to blow things out with clean dry air ya I would now say that may have did you in.. vacuuming will cause static and is not a recommended way to clean things .. I hope I'm wrong and its not but lets see if some one chimes in on that and see what there opinion is ....

Damn, I sure hope I haven't caused anything critical to fry. I did however vacuum it very carefully and in a way that I think it's very unlikely for any static to have got at my hardware. If it's the RAM then there's no panic and I can just go pick up some new ones. Everything seems to be booting up well though except the memory, can't know for sure about the CPU either because I haven't taken off the CPU fan to check if it heats up when powering up, but I think the CPU being fried is highly unlikely.

I hope someone can help me with what the error LEDs could indicate and how to proceed. Thank you to both of you that have already offered some help.

don't know dude you can start spending on new parts that may or may not work . what if the board is bad and some how zaps the new part ? it blow to be where your at with this and I have been there my self. depends on how much your willing to spend on it before it cost you more than a new build?

I found this at gigabyte uk but don't know if it applies to your board or not and you stated 2 beeps above

The POST beeps indicate the following:
1 short: System boots successfully
2 short: CMOS setting error
1 long, 1 short: Memory or motherboard error
1 long, 2 short: Monitor or graphics card error
1 long, 3 short: Keyboard error
1 long, 9 short: BIOS ROM error
Continuous long beeps: Graphics card not inserted properly
Continuous short beeps: Power error

looking around at that 2 beep thing may be a corrupted bios [???] see you may have zapped that bios chip during cleaning really don't know but its now there to look at ... also I found that if the drives were not set right as with the correct sata ports and boot order it may cause this [??] so re check the optical and hard drive to be sure there in the correct sata port and correct in the bios .

No, vacuums suck air from the board, not spray air. Therefore, any static charge generated by the motor would never get close to the components.

Also the motor is encased in plastic. There is no way for static electricity to conduct towards the tip of the vacuum.

The only way static electrity can build up in this case, is from the rapidly moving air molecules that are hitting each other across the surface of the motherboard. However, this is not significant enough to cause damage, and the same thing occurs when using an airduster.

ok why don't you start a thread on this and see what all the toms folks say on that matter .. but you keep on believing in that.. and good luck to you with it i'll take my chances trying to be as static free as I can when working on my parts ... you know I may have been born at night but not last night

No need to start a thread. Its already been done:http://www.tomshardware.com/forum/283255-31-safe-vacuum

Needless to say, I respect that you don't feel comfortable with using the vacuum, and that's perfectly fine. It sure doesn't hurt to be extra safe.

@OP any progress on getting those error codes from the mobos manual?

I wanting to know if that board has 2 bios chips on it and does it use a jumper to switch them over he may have sucked it off and its trying to look at them both and getting crossed up? also needs to check if a jumper or something from another part of the board is now gone and in the vac bag
