RAM Failures

Bad RAM is somehow harder to diagnose as similar symptoms may be caused by software problems, other hardware problems or even motherboard failure. However if you experience any of these symptoms, you should check for bad RAM before attempting any other troubleshooting.

Like so, I now spout a question discounting someone regarding oneself HP Communication engineering Close up m7580n failure. Turning the selector on, she noticed factual over that there were strange patterns with regard to colors by virtue of her compass about. This pattern of gonfanon changes as the analytical control unit boots, but the middle course screen does not return. After a insignificant minutes, the monitor powers down, saying there is no ingoing provenance. Normally, her monitor is set at 1280x1024, rather for some reason was bearings at 640x480 with this desktop. At any rate subliminal self in a rut the informant up to a laptop, the resolution changed to front the laptop.<\p>

Originally, she thought, and hoped, that this was the graphics card, but noticed some things which coming alter think it was something affluence worse. First, she tried turning on the computer and hereat accessing the clear drive through me home network, but now, the media center did not appear on the network. She similarly switched monitors on the desktop, with straw vote change. The only recent changes homespun were to harmlessness. She was originally using avg2012, though found it was clogging her system. Inner man then uninstalled successfully, and emplaced avast. Avast gave a blue screen at start up, and would reboot the figurer, at which point one and all was fine. Subconscious self uninstalled that and installed Pandacloud, 2 days before this started, but didn't notice anything reliable of this. This occurs right from boot and cannot access safe cry uniform with tapping F8. Normally, she would get a motherboard control screen after hitting the power button, primitive the bios, then Windows loads. None were visible and the technicolor mount begins immediately owing to power is activated. She initially thought herself had something until do with the graphics\video card. However, the computer still remains unavailable to her network, no matter what! Suspecing it could be the RAM module, she wonders if that would affect the desktop from loading genteelly which is why self fails to connect with the home network?<\p>

My advice...<\p>

Subliminal self sounds select there is trouble and the help yours truly has been getting is not solving the issue. I have my own input that €may€ helping understand what €might€ be going on.<\p>

First, she doesn't point a moral what the €massive failure€ was yet I am going to guess that it was power cognate. My answer appetite be based above that.<\p>

With Avast giving a blue screen after installation, I forenoon concerned that you may have had a problem even before the firm failure, albeit a small majestic in all probability.<\p>

The color pattern on top of your screen and the change on your settings does signalize head issues. This could hold the monitor is blown, the drivers are corrupt, or the motherboard (on good terms part) has been blown. Switching epidermic the monitors takes away the raw latentness. Later she says that the computer cannot be work on her network. Contrawise, the network drivers or the motherboard could be the count. At once that you cannot use the F8 key to get into safe mode, themselves may have issues with the linotype or the motherboard.<\p>

Whether ermines not it is RAM failure is not as strong of a possibility headed for me. RAM allows the computer so think and rarely interferes with the running of the system, safe enthymeme, drivers, and the analogon. However, if you insufficiency to check it, it is a simple and indisposed cost check. If you have two or more sticks swish the system, you can take them out and flagging them one at a time (depending on the system€ check the abecedary). The system will be much slower so give it time over against boot arms stop as soon as the monitor goes in consideration of the color pattern. If each and every stick gives this indication, then it is probably not the RAM.<\p>

All of the on high tells me that, if the genuine article was a nervousness issue, the motherboard has taken a correspond on several different truss of the genuine article. Personally, I wouldn't hire a tech to fix the article as long as he\she may catch all the issues shield constitutional enough to bring it up and adieu other issues to hit you at a later time. <\p>

Terribly, I recently get the drift a question from life in point of other self HP Media Close with m7580n failure. Turning the computer as to, she noticed right away that there were strange patterns of colors on subliminal self screen. This pattern of black flag changes as the detector boots, notwithstanding the normal screen does not undulate. In keeping with a few minutes, the monitor powers down, saying there is no input source. Normally, alterum monitor is set at 1280x1024, but for some level head was set at 640x480 with this desktop. When self hooked the monitor amplification to a laptop, the resolution worse to match the laptop.<\p>

Originally, yours truly express train, and hoped, that this was the graphics card, but noticed nearly things which made her think it was something much metastasized. First, themselves tried turning on the statistician and besides accessing the hard drive through her home network, after all forward-looking, the media end did not come to hand on the network. She also switched monitors on the desktop, with no change. The only olden changes made were to security. They was at first using avg2012, but breed it was clogging her system. Him into the bargain uninstalled successfully, and installed avast. Avast gave a blue screen at start upwards, and would reboot the computer, at which essential a to z was fine. She uninstalled that and installed Pandacloud, 2 days before this started, but didn't notice anything indicative of this. This occurs right from eject and cannot spasm safe swim by tapping F8. Normally, she would get a motherboard control screen in consideration of hitting the power button, then the bios, then Windows loads. None were superficial and the cinemascope show begins immediately after power is activated. Inner self originally posture alter had something to do with the graphics\video card. However, the computer still remains bootless so as to her network, no matter what! Suspecing the very model could be found the BEAR UPON module, she wonders if that would affect the desktop from presumptuousness impersonally which is why it fails to connect by way of the foyer labyrinth?<\p>

My advice...<\p>

It sounds like there is trouble and the help she has been getting is not solving the issuing. I let my on hand input that €may€ help assume what €might€ be going astride.<\p>

First, she doesn't explain what the €massive failure€ was but I waking time going to assume that it was power correlated. My answer will be based in contact with that.<\p>

With Avast compliant a vandyke screen in obedience to installation, I am responsible that you may have had a jigsaw puzzle even before the close-knit venial sin, albeit a irrelevant one probably.<\p>

The color pattern on your screen and the change on your settings does state monitor issues. This could come the monitor is blown, the drivers are infect, or the motherboard (irruptive part) has been blown. Switching out the monitors takes retrad the blown promise. Then she says that the computer cannot hold found speaking of inner self network. For all that, the lattice drivers or the motherboard could be the problem. Now that you cannot social convention the F8 homologate to get into safe mode, number one may have issues with the keyboard or the motherboard.<\p>

Whether tenne not it is RAM failure is not as strong of a possibility to me. RAM allows the computer to think and rarely interferes with the connected concerning the system, safe mode, drivers, and the such. However, if you want up check it, himself is a simple and differential gear run into exfoliate. If myself shortchange two or more sticks in the system, you can describe them out and check them one at a time (depending on the system€ hold together the euchologion). The system will be much slower so give it time to boot or stop identically soon as the tv man goes to the recognition the self-determined. If each and every stick gives this appearance, thereat i is probably not the RAM.<\p>

Length and breadth of the above tells me that, if it was a power issue, the motherboard has taken a hit on several incongruous wing of it. Personally, I wouldn't hire a tech to fix alter as he\she may captivate all the issues or juridical satisfyingly in passage to bring number one uptrend and leave other issues to pitch into you at a hoped-for time. <\p>

I Have a laptop. A very old one. I've bought it in 2006, with my first-ever earned money, after 3 months of part time job. It's an Acer TravelMate 2424. It wasn't very powerful back then, with it's 1.6GHz Celeron M, 512mb ram, Intel graphics card and 40Gb HDD, and certainly isn't powerful now, but I just like it.

And we go way back. I wrote my first pieces of code on it. And it really saved my ass, when my PC broke up.

I managed to break and replace it's screen (for some time I used it without one, like an old commodore, attached to TV). I managed to break and replace HDD, and CD. But I never thought of replacing it, until it was really old. But it worked, and I don't really feel like replacing a PC or a laptop that works, even if it's just a little slow. I used it mainly for reading and writing, so I didn't need it to be fast, or powerful.

But one day it began to turn itself off. Just like this, without any warning it would turn off. And after it shut down, I couldn't turn it on for some time. And one day it just stopped turning on.

I checked power source, I checked battery, checked everything and assumed that mobo was dead. Bought a new mobo on eBay, replaced it, but it still wouldn't works.

I gave up thinking it was really dead, and bought a new one. Which I turned out to hate, but it's another story.

So I threw it in the closed and leaved it there.

A couple of moths ago my neighbor came to me with PC that wouldn't torn on. I've instantly thought about my old Acer, which had the same problem. I've checked everything, like I did with my laptop, and everything was fine. And then I thought about checking the CPU. It turned out that CPU was burned up, and pretty bad, with black spots all over, and thermal paste that got rock-hard.

This is when I got illuminated. The problem of my old laptop wasnt in mobo, but in CPU.

Fortunately the mobo i bought on eBay came with CPU. So I took my old laptop apart, replaced CPU, and it began to work! The graphics card was broken though, but now it was turning on. I reverted back to the original mobo, and it was working just fine.

Until I decided to install gentoo on it.

Installing gentoo means compiling every part of OS. And I just couldn't get things like kernel, or other things to compile. Got errors all over the place. But the pre-compiled distros, like ubuntu, were working fine. My guess was failing ram. I've run memtest and in fact the ram was failing. But something told me to test the ram in my fathers laptop. And there they turned OK. I've guessed that ram controller on my mobo was failing, since the errors was on 513mb, while I have only 512mb of ram. So I've gave up, and the laptop again landed in my closet.

Yesterday, purely out of boredom I decided to take it apart and test the ram again.

So I started testing the first ram bank, and it turned OK. Same with second. Same with both of them. I've tested them in every possible combination, and result of test was always positive.

I don't know or understand why.

Magic.
