Ultra 40 hangs right before memory test during POST

While I do enjoy using my Sun Ultra 40 Workstation, there is one thing that bothers me. And I am wondering if I can get a help from you guys.
Before I describe what I am experiencing, I politely ask you not to tell me to go other place for using Windows O/S. :)
Anyway, here's what happens:
Ultra 40 hangs right before Mem check during POST (Power-On Self-Test) when rebooting after running h/w monitoring software such as Speedfan or EVEREST Ultimate Edition to see CPU temps or Fan speed of my Workstation.
It seems that my keyboard is working since I can warm-reboot by pressing Ctrl+Alt+Del and I can see Num Lock light goes on when pressing Num Lock key, but that's about it.
Even rebooting my system (either cold-boot or warm-boot) won't help me getting through POST. And I won't be able to go into the BIOS (CMOS) Setup Menu, since Menu screen comes up after Memtest during POST. As I stated before, it just doesn't do anything when it's supposed to run Memtest during POST. Plus there is no BIOS (CMOS) menu to turn Memtest off.
Only way to make my system to pass the POST process is to disconnect the actual power cord and reconnect it. Then it reboots fine.
Does anyone know what's going on?
Is this BIOS firmware related bug?
I am desperately seeking for help.

Unfortunately, this shining blue globe we all live on
is split into regions of responsibility as far as Sun's techsupport is concerned.
Consequently, system serial numbers are registered for their respective geographical regions.
Asia and Pacific is referred to with an abbreviation of APAC.
Europe, Middle East, and Africa is the EMEA area for support.
The Western Hemisphere is further split. North America is one support region
and Central America is grouped with South America for their own support responsibilities.
In this way, Sun gets local people to help where the equipment is sold, without any language barriers.
You need to go back to your local support center, refer back to your case number,
and request they go through an escalation procedure for a second examination.
If this effects you there is a chance it may effect thousands of owners of that model computer.
They send it through escalation reviews in your APAC support,
and they may decide to open a North American case, for the sole purpose of a review of the issue.
(After a local escalation, they may not need to consult North America,
because there may already be an answer in a database that your first engineer overlooked.)
There is no mandatory rule that they must escalate out of their region.
Your local Sun Microsystems people get back to you on your local case number
when there is any sort of an answer.
This may all seem complicated or maybe have too many layers of procedure,
but it is done so that everyone in Sun gets it all documented
into the troubleshooting databases, and gets trained where to find the answers.

What triggers the prompt for memory test during boot up of WLC.

I have a controller that sometimes does and sometimes doesn't prompt for memory test at boot up. What triggers the prompt for memory test at boot up?

We have the same behaviour with a 4402 controller.
After a software upgrade from 4.2.130.0 to 4.2.176.0 the controller didn't reboot automaticly during the first restart with the new software. I connected via console and saw this message:
Airespace 4200 Wireless LAN Switch Board - Memory Test
Invalid Option...Press any key to continue
Airespace 4200 Wireless LAN Switch Board - Memory Test
1. Restricted [4kB per MB]
2. Entire Range [512M]
3. EXIT
Then I choosed option <3 Exit> and the controller started correct.

V120 Fails Core Memory Test

I have a V120 which will not get past the Core Memory Test. I have tried installing a different 256MB DIMM card into all 4 slots to no avail. The system recognizes when and in which slot the card is installed, but I am getting the same error message.
Any recomendations would be appreciated.
Thanks

No, It is not making it past the LOM to get to the console at all. The only way of seeing the memory failure is by setting the bootmode to diag. The boot up just hangs after the memory test until I return to the LOM prompt.

XBench Results - Memory Test Only Request

I upgraded to gigaram 2x1GB and want to see if the memory performance is different. Theoretically anyone that has a Solo should get the same throughput results with 512 as they would with 1GB or 2GB from Apple as they are all in matched pairs. Not sure what XBench really spits out but it's a start. I am trying to see what matched pair performance gets you vs. unmatched. There are lots of claims out there of "significant" differences and I agree that there would be but I want some tests run. Can you run Xbench:
http://www.xbench.com/
and just run the memory test and post results here:
Thanks,

I'll post mine in a separate post.

How to measure memory consumption during unit tests?

Hello,
I'm looking for simple tools to automate measurement of overall memory consumption during some memory-sensitive unit tests.
I would like to apply this when running a batch of some test suite targetting tests that exercise memory-sensitive operations.
The intent is, to verify that a modification of code in this area does not introduce regression (raise) of memory consumption.
I would include it in the nightly build, and monitor evolution of summary figure (a-ah, the "userAccount" test suite consumed 615Mb last night, compared to 500Mb the night before... What did we check-in yesterday?)
Running on Win32, the system-level info of memory consumed is known not to be accurate.
Using perfmon is more accurate but it seems an overkill - plus it's difficult to automate, you have to attach it to an existing process...
I've looked in the hprof included in Sun's JDK, but it seems to be targetted at investigating problems rather than discovering them. In particular there isn't a "summary line" of the total memory consumed...
What tools do you use/suggest?

However this requires manual code in my unit test
classes themselves, e.g. in my setUp/tearDown
methods.
I was expecting something more orthogonal to the
tests, that I could activate or not depending on the
purpose of the test.Some IDEs display mmeory usage and execution time for each test/group of tests.
If I don't have another option, OK I'll wire my own
pre/post memory counting, maybe using AOP, and will
activate memory measurement only when needed.If you need to check the memory used, I would do this.
You can do the same thing with AOP. Unless you are using an AOP library, I doubt it is worth additional effort.
Have you actually used your suggestion to automate
memory consumption measurement as part of daily builds?Yes, but I have less than a dozen tests which fail if the memory consumption is significantly different.
I have more test which fail if the execution time is siginificantly different.
Rather than use the setUp()/tearDown() approach, I use the testMethod() as a wrapper for the real test and add the check inside it. This is useful as different test will use different amounts of memory.
Plus, I did not understand your suggestion, can you elaborate?
- I first assumed you meant freeMemory(), which, as
you suggest, is not accurate, since it returns "an
approximation of [available memory]"freeMemory gives the free memory from the total. The total can change so you need to take the total - free as the memory used.
- I re-read it and now assume you do mean
totalMemory(), which unfortunately will grow only
when more memory than the initial heap setting is
needed.more memory is needed when more memory is used. Unless your test uses a significant amount of memory there is no way to measure it reliably. i.e. if a GC is perform during a test, you can have the test appear to use less memory than it consumes.
- Eventually, I may need to inlcude calls to
System.gc() but I seem to remember it is best-effort
only (endless discussion) and may not help accuracy.if you do a System.gc(); followed by a Thread.yield() at the start it can improve things marginally.

BIOS hangs during post

Well I decided to start a new topic on my continuing problem. I reinstalled my memory in the correct config. (DIMM 1 and 3) but it still hangs during POST. I cleared NVRAM, cleared CMOS settings and reloaded the defaults. I have counted the number of times I have to hit the reset button before it decides to load. It is usually 3... I am at a complete loss as for what the problem is. When it works, it works fine, but more often than not, it hangs and the LEDs on my DDR hang also...The memory is brand new so that's not a problem. This might be more of an annoyance than anything that I can fix, but I really don't understand...

Yes, all corsair RAM is warrantied to 2.8V, except PC4000 and above, which they warranty to 2.9V. If you wish to clarify this with them direct then read or post here
I think there is a compatibility problem with this chipset / memory combination, please read:-
https://forum-en.msi.com/index.php?threadid=24288&sid=&hilight=twinx+3200c2
and
http://www.houseofhelp.com/forums/showindex.php?s=d70e4df71151b858162832276f5f31d1&threadid=14984&highlight=twinx+1024+3200c2
I suspect that PAT is playing a part in this, but you need to confirm this via BIOS.
In Frequency / Voltage Control
Do you have Performance Mode: Slow.
If so, I would try manually setting timings:-
Advanced Chipset Features
DRAM Timing Setting
Configure DRAM Timing by SPD: Disabled
CAS Latency: 3 Clocks
RAS Precharge: 4 Clocks
RAS to CAS Delay: 8 Clocks
Burst Length: 4 Clocks
Integrity Mode: Disabled
and see if you can post.
Second thing to try is just one memory module at a time and run Memtest on each and see which errors.
If you still can't post at relaxed timings, see if trying some NoName PC3200 memory does the trick!
Unfortunately, the only DDR400 Corsair Memory Modules listed in this mobo's Compatibility List is the CMX512-3500C2PT and I have a feeling I've read somewhere that the a fix was implemented on these modules to ensure compatibility.
I would post on the Corsair forum, and see if you can't persuade them to swap your modules for a more compatible type.
The benefits of Low Latency memory on the 865 / 875 chipsets (all manufacturers) are the subject of much debate anyway and whilst opinion is as ever divided, I am firmly in the higher frequency is better than lower latency group.
Hope this helps.

KT4VL Memory test HANG

System Specs:
2000+XP
KT4VL
GeForce2 TI 64MB
Maxtor DiamondMax Plus 9 60GB
DDR Modules tried:
Samsung PC2700 (256 & 512)
Nanya PC2700
Antec True 430
I just put this system together today and it wont get past the memory test according to the D-LED. I tried all three of these DDR Modules (in all three of the DIMMs- one at a time). The system never gets past this test and hangs at this point.
All the listed DDR work in my other systems yet this mobo wont do anything. Very frustrating!!!
So far I have cleared the CMOS... removed all the other PCI cards besides the Graphics Card.
The PSU works with my other 2000+XP system (KT3 Ultra2) so I know its not the psu or anything of the sort. I am clueless on where this problem lies. The bios never even gets a chance to load ... and there isnt an OS on it yet since it never gets past the mem test during startup.
Please help- Want to know if its the mobo or something else.

Pazul,
I don't really get you clear. Are you using 1 stick of RAM and you have tried 3 different stick and none of each of them work?
Or you try to put 3 sticks of different RAM occupying 3 slots? If so, I would suggest you swap your RAM to 1 or 2 identical one. Occupying all 3 slots with different RAM is only to find problems.
As you're mixing different type of RAM, at most you can go is just 2 sticks of RAM, on slot 1 and slot 3. Unless you want to slow the RAM to run at only PC1600 speed, else this is not very feasible to do so.
Also, check each stick of your RAM with http://www.memtest86.com

KT3 Ultra memory error on POST

I posted this problem to the MSI newsgroup a while back. I got some help, but was not able to resolve the problem. Now I'm trying these forums.
I have a strange, annoying problem:
When my system shuts off in normal mode, it locks on memory test next startup. After the failed boot, it will start after the power is cycled.
It does not fail if the shutdown is from a crash (ctr alt del).
It is not windows, I have tested it with a boot disk without starting windows - same behavior.
It is not that power to power supply is not shut off. If I cycle power BEFORE the failed boot, the boot still fails.
It is not the memory, I have confirmed the memory works in another system, and I have tried other memory in this system with same results.
It is not the power supply, I switched it out with another and same results.
I have removed all PCI cards, and the problem still happened.
My system:
XP 1700+
512 M crucial PC2100
350 W Antec PS
Please help.

I have the same problem,
however, if i turn off the power supple after i turn off the computer, and then the next time i wanna use the computer, i turn them both on, it works fine
but if i forget to turn off the PSU, and turn on the computer the next time i get the beeps and i gotta reboot
some have said switching powersupplies fixes the problem, some say switching ram fixes it
i say a bios update should fix it

Problem with P45 Platinum during POST

Good day!
I have MSI P45 Platinum mainboard and from to time to time it freezes during POST with AMI bios POST code - 423C. This happens right after the message that "4096MB OK" and before the detection of SATA/IDE drives. When this happens, the only way to make the system run is to turn off the power (pressing Ctrl-Alt-Del of Reset would result in the same error) - after that the POST procedure finishes correctly and I don't experience any problems afterwards (system is rock-solid after POST completion).
So my question is - can anyone explain me what does this post code mean (D-Leds are not much of a help)? Is this a mobo problem or may be there is some kind of incompatibility with my hardware. I should mention also that I've tried all versions of Bios both official and beta without any success.
This problem does not trouble me that much (doesn't happen often), but still I would like to understand what may cause it.
P.S. My system config - iC2D E8300/MSI P45 Platinum/4x1Gb DDR2-800 Geil Black Dragon (5-5-5-15)/MSI Radeon 4870 1Gb OC edition/HDD 250 Gb WD + 120Gb Seagate/SB Audigy 4/DVD-RW Asus 1814/PSU TT Toughpower 700w (w0105)
Thanx in advance and please excuse my poor English

Thank you for the reply!

What is your current BIOS Version?
I've recently flashed the latest beta bios version - 1,5 beta 6... but it produces the same error as did the latest official bios v1.4
Quote from: Jack the Newbie
Does the same problem occur with only one memory module installed?
I don't know actually. But thanks for pointing this out - I will test the system with one (and then with two) module(s). I've tested the modules with the memtest86+ software (the latest version, which supports P45 chipset) several times and it showed no errors. So the modules are OK and they worked without any problems with my previous mb (Gigabyte P35-DS3).

What do the POST-Status LEDs of the board tell you, when the system freezes at the described stage?
Well, I guess I don't fully understand what does the combination of LEDs tell during the freeze. I'll try to describe the combination -
LED12 - OFF LED13 - GREEN
LED8 - RED LED7 - OFF
LED14 - OFF LED10 - GREEN
LED15 - RED LED11 - OFF
In mobo's manual this diagnostic LEDs are grouped in 4 groups and the description of the group that most closely resembles my case is - "Testing base and Extended memory etc." But I'm not sure that I'm identifying the problem correctly, because of the LEDs that are OFF.
Quote from: Jack the Newbie
Are you experiencing any freeze and/or stability problems appart from the described problem?
No, as I said in my initial post, once it get past this stage everything is running smoothly - OS boots and all software, including the most demanding games or tests, are running OK.

P45 platinum gets stuck on Base and Extended Memory Test

First my system specs:
MB: P45 platinum
CPU: Intel Core Duo Quad Q6600
GPU: Nvidia Evga 8600 GTS 256MB
RAM: 1x 1GB OCZ Nnvidia PC2 6400 dual channel 1x 2GB Corsair
OS: Windows XP Pro sp3
Well my current problem is that when i turn on my computer it gets stuck on Testing Extended and Base Memory according to the LED lights, sometimes if i wait it will start up the system and sometimes it wont, this has been happening for about a week. Also another thing that happens is that it blue screens me sometimes when its starting up and restarts not sure if this is a OS or a motherboard issue. Previously when it was doing the extended base memory test it would reset right there several times even before starting, when it does start i have no issues though, would really appreciate if anyone can help me with this, thanks before hand.

If you got hang while trying to go into BIOS, it means that a hardware is failing depending on where it is stuck at. I suggest you hit esc key during bootup and see where the bootup hangs at.
I have the splash screen disabled so can see exactly where its happening. Initialises USB devices, two beeps, then stops at end of memory count 4gb. The only other time it doesnt load is when my monitor doesnt kick in and the LED's stay on initializing video interface.
After work today it took about 20 reboots to get it on. You can still input keyboard commands when it seems to halt, i shall describe:
if you press 'del to enter setup' you get loading setup... (doesnt enter BIOS screen)
or
press 'f11 to load [something]'... (doesnt enter BIOS screen)
The only other information I can give is a three letter/digit code on the bottom right of screen.
I seem to have ruled out overclocking and BIOS versions as they still happen now I have controlled the factors (changed BIOS' and default non-overclock settings).
This used to be very infrequent however is every time I boot up now. Like you say some hardware is failing, whether its a cable, psu or other component I just do not know...
* also it seems to be happening to other users who have completely different hardware to me

865PE NEO2 FSIR fails memory tests

This is the second MB that I've had this problem with, so something is causing them to fail. Here's the story:
New install, 865PE Neo2 FSIR + P4 2.6GHz 800MHz FSB, 2 x Crucial PC3200 256MB DDR, everything seems ok, XP installs with no problems.
About a month down the road I'm plagued by sudden reboots, Microsoft Error Reporting says RAM, says to DL and run it's DOS memory check utility. I get the utility, create bootable CD and run the utility, computer fails all RAM checks. I pull each RAM stick in turn and re-run the check with each stick separately, still fails all tests. Shortly after this, the board refuses to POST. Ship the board back to New Egg for replacement.
Installed replacement MB with 4 x 256MB Crucial PC3200, Microsoft DOS memory check program passes, no problems. About 2 weeks later I run into minor instability so I run the same memory check again, the board fails all tests????? I pull all Crucial memory sticks and put in a test stick of Corsair XMS 3200; same result, failure of all memory tests.
At this point, WinXP still runs, but this is the same pattern that the other board showed, right until it quit altogether.
It occurs to me that I DID flash BIOS to 1.9 between the time I first tested the RAM and got a pass and the time I tested and got a failure, could this be a coincidence? I can't remember if I updated the BIOS on the first board or not, so this may mean nothing.
System Specs:
MSI 865PE NEO2 FSIR
P4 2.6GHz, 800MHz FSB (all defaults, no overclock, Vantec HS)
Crucial CT3264Z40B.8T PC3200, CL3 256MB (2 Modules)
Crucial CT3264Z40B.8T2 PC 3200, CL3 256MB (2 Modules)
(Tested with same results with single Corsair CMX512-3200C2PT 512MB)
Antex True Power 430W PS
ATI Radeon 9600 Pro
All PCI slots open
Seagate 120GB System drive, 7,200RPM primary master
IBM 30GB drive, 7,200RPM primary slave
LiteOn DVD ROM secondary master
Sony CDRW secondary slave
2 x IBM 30GB drives on Promise PATA.
I know I'm probably gonna have to RMA this board, but I'd really like to know what is causing this so I can avoid it next time.
If anyone has any ideas I'd sure appreciate it.

--BUT--
Suspect it is the reallocation for the P4 EE that is the issue. Reason is that Memtest86 has been running on that box for 9 hours now with NO error. However, it also shows only 104K of reserved memory. My other 865 board with onboard RAID (an ASUS P4P800 Deluxe) shows 687K reserved. So either the ASUS is wasting a lot of space, or the MIS is no longer correctly indicating the amount of memory reserved by the BIOS (including the Promise BIOS) at startup. Then Microsoft's utility is not correctly scanning. But Memtest, which probes for the "correct" setting, is. (The Memtest86 version is 3.0, and the test was done with the Promise enabled and drives attached (so the BIOS loads) and all the other setup was as it would be normally (standard IBOS options, etc.)
So who's right? And if MS' tool has the problem, does that indicate Windows XP reads memory the same way? Hmmm...
Hmm, I haven't tried reverting BIOS, but I'm typing this on the affected machine (which Memtest 86 says is fine) with only the two RAM chips it likes and so far no problems; I've run PCMark4 and 3DMark4 benchmarks all night and no problems, it was still happily churning away on 3DMark this morning. I guess either one of the Crucial sticks it doesn't like is bad or Crucial changed something in a revision to the chips it doesn't like.
Just a FYI, the Crucial sticks it DOESN'T like are CT3264Z40B.8T2
The sticks it DOES like (at slow or fast performance, forget about turbo or ultra turbo) are CT3264Z40B.8T
Both pairs are PC3200, CL3, 256MB DIMM's, single sided.
I think you're right about Microsoft's RAM tester being buggy, I can't believe ANYTHING could run if the RAM was actually giving the errors it shows, EVERY test shows things like "expected result 11111111 actual result ff1e0001" The Microsoft tester does run fine on the other 5 computers here; a mix of laptops and desktops; none using this board. It also ran on this board when it was installed, I guess the BIOS upgrade must be the cause.

MacBook Pro 2,2 won't pass memory test at boot

Hi Apple and Mac folks,
I have a MacBook Pro 2,2 15", 2007 year model, equipped with 2,16 GHz Intel Core 2 Duo and 2 GB 667 Mhz factory-installed DDR2 SDRAM, running Mac OS X 10.4.11. SMC version is 1.12f5.
Three months ago, when I was installing the Safari beta and the installation requested a reboot, the machine wouldn't start at all. It didn't give me any startup chime; the only thing to be heard was the initial movement from the DVD scanning mechanism (?), but after that nothing happened. If I waited for a while I could assume that the CPU was working, since I could hear the fans spinning up. But the screen was black and the computer wouldn't load any CDs or DVDs or even listen to any keyboard commands. The only thing that was working was the force shutdown by the 10-second press on the start button.
After some trial and error I realized that the system would reboot without problems if I let it rest (cool down?) for about 15 minutes. Sometimes, connecting an external hard drive via FireWire would also help the system to start up, bit it seemed to work rather randomly.
I ran the Apple hardware test and it reported an error on one of the SDRAM modules the first time I checked, but running the more thorough test wouldn't report any error and the system didn't show any signs of errors whatsoever once it was up and running.
I have also tried to reset PRAM and SMC, but it does not alleviate the reboot problem.
Since I then suspected that I had a faulty memory module I decided to upgrade the system with 2 Kingston DDR2 2GB SODIMM modules (yes, I know it only supports 3GB of memory, but I wanted the modules to work in pair). Unfortunately, the system exhibits the same problems with the new modules, and now things are getting even worse - now the 15-minute cool down period does not seem to be sufficient to get the system to pass (as I suspect) the initial memory test.
Last night I had to fiddle around, switching memory modules around in the slots to get the system restarted. I could get it rebooted once with one of the older 1 GB modules in the upper slot, and once it rebooted with an older module in the lower slot. Things seemed to act quite randomly and the previous cooling period method didn't seem to make any difference. Finally, I sort of gave up and put back the two new 2 GB modules and tried a last restart while having an external hard drive attached via FireWire and then it gave me the chime and restarted!
My interpretation of the problem is that the system has some kind of glitch (maybe not the correct term for a small gap in the circuits?) in the circuits connecting one or both of the SODIMM modules and that this glitching is getting worse as the system grows older.
So, I have three questions to you:
1. Is there any way to turn off or circumvent the initial memory check, so that I can temporarily live with this problem and not risk having an unusable system at next reboot?
2. Have you heard about this kind of problem before and maybe have knowledge about what part of the system that would have to be replaced and what it will cost me if I bring the computer to a service station (I'm located in Sweden).
3. Are there any SMC or EFI updates I should try before going to service?
Thanks for any help on this,
Ulf

The firewire bridge is the most likely component in a FW HDD to fail. I have seen it a few times, and all that was needed was to remove the drive from the case and place it in a new firewire enclosure. I insist on getting an enclosure with an Oxford chipset, as they are the most reliable.
Hi again Cornelius,
first of all, thanks for the support in the struggle troubleshooting this issue.
Secondly, I don't think the problems has to do with the cabinet of the externa FW drive, but rather the problem would be located in the FW port in the computer.
Doing some research today, I found indications on that the AHT actually is installed on the hard drive of MacBooks after 2007. So, I decided to see if I could launch the AHT from my internal hard drive. Reboot needed, so hold your thumbs...
Reboot. Dead computer. Attached firewire disc. Dead computer. Let computer rest and cool down for half an hour. Restart -> dead computer. Connected firewire drive -> chime and boot!
Pressed D to load ATH. System gave me a dimmed screen with a text box telling me that I had to reboot the computer. I gave OK to that and the computer restarted normally, but reported an abnormal shutdown and gave me the opportunity to send a report about a kernel panic to Apple.
When the system came up the attached FW disc was not reachable. Looking in the system log, I find the following error message repeated:
Jun 26 16:24:49 Ulf-Kronman kernel[0]: FireWire GUID ffffffffffffffff is invalid!
The research on the net is getting me more and more confused: Is the ATH really located on the hard drive of MacBooks? Is the Power On Self Test really run at reboot? According to this wikipedia note (http://en.wikipedia.org/wiki/Power-on_self-test) the test is not run at reebot:
" Apple's Macintosh computers also perform a POST after a cold boot. In the event of a fatal error, the Mac will not make its startup chime. "
But my problems occur both when I cold start and when I reboot.
Isn't a lack of chime a very un-Apple-like way of reporting an error? Where/how can I get some more information about what's going on before the chime? And how do I know if the Self Test is run or not? System profiler only reports that self-test at start hasn't found any errors, but only when the system starts (due to that it not has found any errors )
Somewhere I saw instructions for doing a
Terminal> sudo nvram boot-args="-x -v"
to get a report of whats going on during startup. Could that be a way to proceed or is there a leaner way to get info out of the self test?
I'll continue to some research on the FireWire GUID, whatever that is.
Regards,
Ulf

HP Pavilion g6-2330dx. "No Boot Device. Insert boot disk and press any key" Memory test failed

Hi. So I am trying to help a friend with her laptop. It's a HP Pavilion g6-2330dx.
Product #: D1C01UA#ABA
Serial #: [Personal Information Removed]
Windows 8
ADATA 4GB RAM
Toshiba 640GB HDD from the looks of it.
The laptop is unable to boot into Windows, so I suspect the hard drive. But I ran the hard drive test and it passed all the tests. The SMART test and both the short and long test. I ran the tests multiple times and it passed each time. I tried reseating the hard drive and still no go. I also removed the HDD and connected it to my desktop PC to see if it detects and it did. Ran the Windows 7 own HDD test and it passed.
Currently, there doesnt seem to be any operating system at all on the HDD. When I check, there is a C: drive of ~90GB partition that is ~90GB free, but inside there are Windows files/folders. There is also a D: drive Recovery partition that says ~26GB with only ~2GB free, but when I go inside there's only ~350MB worth of data.
So then I ran the memory test (in BIOS) and it failed immediately. I reseated the RAM module. I tried the other slot. It still failed. So is it safe to say the memory is the cause of this problem?
Pressing the F11 key that is supposed to take me to the System Recovery only leads me back to the black screen with "No Boot Device. Insert boot disk and press any key"
I even tried to install Windows 7 to see if it'll work. I was able to get the laptop to boot/read off the Windows 7. But when I click to install, it asks for a boot device driver or something like that.
My friend doesn't have the recovery disk either. I guess she lost it.
Anyway, is it as simple as replacing the memory or could it actually be the HDD (even though it passes)?
EDIT: This is what the System Log in BIOS says
0021           Time: 10/13/2014
03F0           Time: 10/13/2014
03F0           Time: 10/13/2014
The date was the first time I ran the tests. I havent received those numbers (error codes?) since.
EDIT: Just for kicks, I ran Memtest 2.11 just now (forgot I had the disc) and it immediately went red with thousands of errors, hah.

Hi bghs,

I understand that you were unable to boot into Windows, and you suspected the hard drive and tested it, but it passed both short and long test. With that being said and the fact that it also passed leads me to believe the hard drive is fine.
You tested the memory and it failed. You tried reseating and swapping slots but they still failed the test.
I would test each card individual with the memtest to determine if it is just one or both cards that have an issue.
When you installed it in another computer, you did see the recovery partition. Once the memory issue is resolved, if you are still unable to boot into Windows, I suggest you do a recovery with the minimized image.   Here is a link to Performing an HP System Recovery (Windows 8) to assist you with that process.
I hope this helps.
