Well,

My friend have a laptop which monitor goes blank random times. I hooked it up to my monitor and it happened the same thing. However; when I take the memory out of the laptop and plug back in. It lasts long without screen going blank. I also set to never in the power management settings and no hibranation or nothing is set up.
I would like to know that what makes computer to work fine for a while after removing the memory and plug back in? Also, he had a virus, spyware and adaware infected hard drive, I did a dos format and when I try to install windows, it went half of the way and hangs up while in the screen in the place where it says creating files to be copied. Second time it copied half of the files before it stops. Third time I remove the memory and put back in, windows installation went without no errors. I did twice and worked great then the screen of the laptop goes blank again. Does anyone has a clue what is this mysterious problem could be? It seems that problem somewhat fix whenever I remove the memory and put it back in.

Several posters describe two related failure patterns: intermittent full blanking that temporarily clears after reseating RAM (noted by ), and partial-screen black regions that appear and disappear (reported by and ). Those are usually two different fault families — intermittent memory/contact faults that cause system instability, and display-path failures (panel/inverter/cable/T-CON or GPU) that produce visible black areas — so troubleshooting should follow a clear isolation path.

Reseating RAM often "fixes" the symptom temporarily because a bad contact or a failing SODIMM will reconnect briefly when disturbed. A practical diagnostic flow: run a bootable memory tester (memtest86+) for many passes; try each SODIMM alone and in each slot; swap in a known-good SODIMM if available. If errors appear or instability follows, replacing the faulty SODIMM is the appropriate next step — that is the inexpensive, sensible first repair. When handling modules, use ESD precautions and clean contacts with isopropyl alcohol or a gentle eraser only if contacts are visibly dirty.

For partial black areas, distinguish internal vs external behavior. If an external monitor shows the same blanking, the GPU/chipset or driver is suspect; if the external stays normal while the laptop panel blacks, the LVDS/eDP ribbon, hinge connector, inverter (for CCFL panels) or the panel/T-CON are the likely culprits. A visible device change in Windows (Plug and Play Monitor vs Digital Flat Panel) is usually the driver reporting mode and not by itself diagnostic of the hardware fault. Avoid risky home fixes like reflowing chips; ribbon reseating or panel replacement is commonly needed for internal-only faults.

Because a Windows install stalled in the original report, check RAM first (see above), then verify the hard drive (SMART/diagnostics) and the install media. If memory and disk test clean and the problem remains intermittent, escalate to motherboard/GPU diagnostics or professional repair — start with the cheap, verifiable fixes (memtest and single-stick testing) before replacing major components.

I am not really understanding what you are saying. Best thing to test is hooking up to another monitor. If not sometimes it is the resolution problem. RIGHT CLICK DESKTOP >>> GO TO PROPERTIES >>> CLICK SETTINGS TAB >>> SOMETIMES IT SHOWS TWO MONITORS 1 and 2 Make sure you select ONE AND HIT APPLY.

So you mean you can perform things because you can see because the only half of the screen is blank instead of the whole thing? I would hook up to another monitor and see also what happens. :rolleyes:

FOR ME, it turned out to be the memory that laptop screen goes blank after about 2-3 hours of working sometimes even early. So I changed the memory and it worked very well since then. :cool:

What do you mean by "I changed the memory"? Do we need to buy a new RAM?

I myself had the same problem. My notebook is Acer Aspire 5550. It is hard to solve this problem cause it happens sometimes only. The left part of the screen becomes black while the other part was OK. When it entered Windows, sometimes it is full screen, sometimes it continues with the problem.

The strange thing is....When the problem happens, my monitor hardware changes from Plug and Play Monitor to Digital Flat Panel display. This is really strange....

I really hope if someone could help me getting out of this irritating problem.
