Looking For A High Quality AC Power Adapter
Nov 11, 2012
I need a new AC power adapter for my monitors. I have three Acer S243HL LED monitors, and the power adapters basically exploded a few months ago (I heard a loud pop, followed by the monitor just turned off). I tested it with a working power adapter (the one I'm using now for my only functional monitor), and the monitor itself is fine. The power adapter is not. Anyways, to prevent this happening in the future, could someone recommend to me a high quality power adapter which won't short out on me?

Is there anyway to have a High Definition/Quality moving background? I've tried dreamscene and searched around, but no luck. I'm looking for something that can make wmv / flv / etc../ into a background.

I'm having problems with my the graphics card on my laptop. It's an APU and I have picture and videos problems. Whenever I watch movies or look at pictures I see most things fuzzy, (if that makes any sense). I tried to watch a DVD and the video quality was unbearable. The most unbelievable thing is it affects picture quality. I can't do anything without poor quality pictures or videos. I have tried installing new drivers and all sorts of things. Is it me or is it my laptop?
My Laptop Specs:
AMD A6 Quad Core APU 1.5Ghz
AMD Radeon HD 6520G
6GB DDR3 Memory 1066Mhz
Windows 7 Home Premium 64bit

I received my copy of Windows 7 Home Premium. I skipped the Vista bandwagon, so I was moving directly from Windows XP Service Pack 3 (32-bit) to Windows 7 Home Premium. I opted to install the 64-bit version of Windows 7, as I had no issues when running the 64-bit beta.
As it turns out, I seem to have encountered an issue with my network adapter on Windows 7. Using any speed test site, such as speedtest.net, I get an extremely high ping (500ms +). I have tested another machine behind my router running Windows XP and there is no problem. Also, on the speed.io website, which tests connections per minute, I can only get around 200 on Windows 7, whereas I could get 2000+ on Windows XP with the same hardware.
Strangely, in games like Counter-Strike: Source, my ping is normal and in the 25-60 range on most nearby servers. Also, when running the ping command from the command prompt, most servers return a result lower than 100ms ... which is also normal. So, I don't understand why on speedtest.net, pingtest.net, and dslreport's flash speed test.. I get a ridiculous ping time of 500+ms. Web browsing does seem to be slow as well, as images take longer to load then they should.
I'm not sure whether this is a driver issue, or what. I have tried disabling both my firewall and AV software, so they are not at fault. I've tried 3 different version of the drivers for my NIC. One from the Gigabyte website, and two from Realtek's website (they released an updated version yesterday). My motherboard is a Gigabyte GA-EP45-UD3R (rev 1.1). I have all of my system specs listed on my profile if anyone needs to know more.

I have a system I am working on that no matter what I do svchost.exe keeps CPU usage on a Quad core hovering around 70-80% and temps in excess of 120F with a ThermalTake BlueOrd cooler installed. It is a custom system I built, with the following specs:
Tech Support Guy System Info Utility version 1.0.0.1
OS Version: Microsoft Windows 7 Professional , 64 bit
Processor: AMD Phenom(tm) 9850 Quad-Core Processor, AMD64 Family 16 Model 2 Stepping 3
Processor Count: 4
RAM: 1791 Mb
Graphics Card: ATI Radeon HD 4200, 256 Mb
Hard Drives: C: Total - 305142 MB, Free - 265597 MB;
Motherboard: ASUSTeK Computer INC., M4A785-M, Rev X.0x, 105424870002755
Antivirus: Microsoft Security Essentials, Updated and Enabled
Usage spikes when Outlook, IE8 and SKype are running after a random time period. I had this system on my bench for 2 weeks straight running benchmark tests and stress test software which all came back "PASS." I scanned for malware, virus, rootkits, etc. to no avail (all clean). Because of the extraordinarily high usage, USB drives are not working properly (take more than 2 hours to come up) and the system is sluggish. This should not be happening on a QuadCore system with a high-performance cooler. I even went so far as to format the HDD and perform a fresh install of everything. It worked perfectly for about 30-min then the BluRay drive stopped recognizing discs, CPU usage spiked up to 70%+ (two cores are at 94-97% usage all the time), and it won't pick up USB devices.

Anyways, in laptops (gaming or not), does setting the power plan to High Performance actually improve gaming (frame rates, speed and anything else) in battery mode? I'm using a laptop (not dedicated gaming, but suffices) and my games (the recent ones) slow down whenever I'm in battery mode. A couple of friends told me I should set it High Performance, which I doubted since they don't seem to be the type to change the power plan settings and more so with the advanced plan settings.

I am traveling to Hong Kong in a couple of months. My HP laptop is from the US. It has an external power brick that takes 100-240V.My question is about the cord that goes from the power brick to the wall outlet. The cord has a US plug. Does the cord also take 100-240V and I just need to buy a plug adapter, or does the cord only take US voltage and I need to buy a new cord?

I just installed windows 7 ultimate sp1 - Like the title says I'm seeing 35% cpu usage with nothing going on. I googled around and ran traces to see which driver it was, turned out the ahci driver was doing it. The USB driver showed similarly high latency but that can be delt with later. Most forums recommend upgrading your drivers but this problem has stayed constant both with microsoft's stock drivers for everything and after running windows built in search for drivers even after I manually grabbed the latest drivers for everything. url...BIOS is up to date4 GB RAM - Corsair something or otherEVGA Geforce 8800 GT450W psu1 DVD burner (sata)5 hard drives (sata) plugged into all but the first sata port because that caused nothing but headaches for me. Update - switching from AHCI to IDE in BIOS fixed the problem.

I have a 1080p LG LCD Monitor.
It has 2 inputs, DVI and VGA. I have two different types of cables, HDMI-DVI and VGA-VGA. I tried connecting my laptop to the monitor.
My laptop has two outputs, VGA and HDMI. When I use the HDMI output, the image on my monitor is sharp and clear. When I use the VGA output and the VGA-VGA cable, the image on my monitor is blurry.
EDIT: My VGA connector also has one peculiarity. From the point of view of the sockets, Pin No. 9 is missing, for both ends. (although it may unused)

I have just upgraded to Windows 7, and transferred a group of photos I used in XP as screen savers onto the new system
I have the same screen as before, but the quality of these photos as screensavers is greatly inferior to how they appeared under XP
I know the images themselves are sharp, but in Windows 7 they are quite "out of focus"
Do I need to tweak anything in Windows 7?

I work as a pianist and have recorded a few videos of me playing the piano using my mini-DV camcorder (a Panasonic NV-GS230). I transferred the videos from camcorder to PC using Panasonic's MotionDV Studio software which has created very good quality .AVI files. When I watch the AVI files on my 4 year old laptop (Acer Aspire 5920 running Vista) the video quality looks superb - the video looks very clear and runs very smoothly. However, when I watch the video on my new custom PC (spec included below) for some reason the video looks a little more grainy/blurry and not quite so fluid/smooth. If I say the video quality on the laptop is 100%, then I'd have to say the quality on the PC is about 75-80%. Here is my PC speec

I just recently received a new dell xps 9100 loaded with an intel I7 six core 930 processor, 16 gigs of ram, 2x1tb hardrives, soundblaster x-fi soundcard, ati radeon 5870 1gb video card and a few other goodies. when im listening to my music while running other applications it starts to crackle and pop and drops in quality drastically. I have tried installing a new soundcard, installed new drivers, changed the power settings and its still doing th e same thing. I am running windows 7 64 as well. The dell technician has even been here and tried to resolve the issue with no success. with the headphones on as well it still does the same thing.
