Flickering after upgrade?

Heres my problem:

For the holidays I received a few upgrades for my computer.
A matching 20"ws monitor and a new PSU a nice thermaltake with modular cables.

After installing everything I noticed a flicker on the main monitor when I would open a folder.
I checked both the refresh rates on the monitors and have them both at 60 mhz (the other option was 59) I have the latest drivers installed and the latest bios for the mb.

It does not do it at random just when opening a folder or something like that. Sometimes its one quick little flicker other times a few longer ones.

What should I do? I have done a virus sweep and had a defrag lately. No spyware that I kind find with a few sweepers.

I am open to any suggestions.
Thanks.
 
I would hate to point at the new supply right off as a possible reason. The list of "good" and "bad" make supplies still only partial can be seen here.

Good:
Akasa PaxPower - Antec(except Smart Power models) - Astec - AOpen - Channel Well - Coolermaster - Enermax
- Enlight - Fortron Source (Sparkle) - HEC - Hi-Power - Jeantech - NSpire - OCZ Technology - PC Power & Cooling - PowerMan
- Seasonic - SilenX - SilverStone - Tagan - TTGI/SuperFlower - Vantec - Zippy / Emacs - Verax - Zalman
- Corsair

Bad:
Allied - Antec Smart Power models(recommend True Power or NeoHE) - Aspire - CoolMax - DEER - EYE-T
- KingStar - L&C - Linkworld - Logisys - PowerMagic - PowerUp - Powmax - Q-Tec - Raidmax - Skyhawk - Star
- Turbolink - Ultra - ThermalTake

Did you have a dual monitor setup prior to receiving the new 20" models? The video card should support it while that also can't not be ruled out. You are not dealing with a virus or malware but hardware configuration issue. Have you tried bringing the refresh rates upto 70-75htz?

are you using a nVidia or ATI card?

Last time I checked, LCD's dont do more then 60

That must have been some time long ago. I run the BenQ 17" model here at 75htz all the time. You set that in the advanced section of the desktop setting for adapter there. You wouldn't want to run an lcd over 75htz however.
 
Lcds will run at lower refresh rates then crts while gaming. This is mainly because an lcd remains constant while crts will brighten or dim when refresh rates are changed depending on whether they are raised or lowered. 100htz is the optimum for most according to the information seen http://en.wikipedia.org/wiki/Refresh_rate

Soupmaker's sig shows that there's a GeForce 7600GT(NVidia) card installed on the system there. The flickering could be the result of the way the vga bandwidth is now being split between the two monitors. That would tend to pull a little more on power through the card itself.
 
do you have that option, "hide modes that this monitor cant support, enabled?

if so.. try disabling that one, and put the refresh rate to 70Hz then. ( dont press anything if you screen goes weird tough, it'll reset if the monitor really cant handle it)
not sure if it would work,. but it would be worth a shot i think (dont change the resolution tough )
 
I would try that as well looking at going through the reconfiguration of the desktop setting for multiple monitors as far as extended desktops. Besides any possible increase of demand on the card you may well be seeing a software problem. ATI has done well with their Catalyst Control Center when running multiple monitor setups. I give them that much.

He has a Thermaltake 700watt powersupply powering a non-powerhungry PC with a 7600gt. Whether the PSU makes your good or bad list, I highly doubt it's the PSU not delivering enough power.

It's not the wattage rating of any supply but the stability that really matters.

I had that problem until I got different drivers and I'm on a CRT, did the same on a LCD...

You are starting to hit the nail on the head there with the possible need for a set of updated drivers for the card itself. Sometimes reverting to an older set rather then the latest can work out better. That model card has out long enough for updates to have passed it by. I've seen that on ATI cards as well where after a certain point the updates fail.
 
So you're saying this powersupply, which costs $165 has stability issues when it comes to handling a system that maybe uses 500watts?

You are going to find that most systems will never even touch 500w. The $165 price tag means nothing if a supply is faulty. But the real problem here and ideas for seeing it corrected have more to do with the Windows/software environment and trying a higher refresh rate to see if those work.

While a supply problem can never be totally ruled out this sounds far more like a software or model card type problem. Some cards are not really good for dual monitor setups while being great for gaming and other things when using a single display. The output isn't sufficient on those models.

The system there needs some tweaking to correct the flickering when going to browse folders. The worst case would be a defect in that one monitor. You could try running that one monitor on it's own briefly to see if any further problems are seen. If so the gift would have to be exchanged by the person who bought it for you. The other ideas should be tried first however.
 
unless you have a voltometer of course, i recently purchased one and its kinda fun :)

FLUKE is an execellent brand for those. The one thing to remember when going to measure current is the need to have a load on the supply itself when you go to use it. And make sure you don't cross the test leads between ground and positive to avoid any possible damage to hardwares or the metter itself. :)
