Screen goes black and mouse goes crazy

[ivanlbc562]

So I have this old computer that was a prebuilt(HP p6510y) and was slowly upgraded. There was a power surge 2 days ago and that's when the problems started. I get 2-3 second black screens when I open the browser or any other program. Opening CSS or GTA IV crashes the pc, CS 1.6 works fine. I ran Memtest86 for 16 passes (8 hours) and had no Errors. I downloaded Seagate Tools and HDTune to check the Hard drive and they both said good health and no bad sectors. Now I'm missing some other programs to test out my other hardware. Do any of you see anything wrong here? Everything should be stock. (would have used fraps but it would just crash the pc)

CPU: Athlon X4 II 630 (Stock - Hyper 212 EVO)
Mobo: H-RS880-uATX (Aloe)
Ram: Generic Samsung PC3-10600
HDD: Seagate ST3750528AS 750GB
PSU: Corsair CX600
GPU: EVGA GTX 470 SC
Other: NZXT 210; NZXT Sentry LX ; 2 Blue LED 120mm Fans; 2 140mm Blue LED Fans; 2 NZXT Fans

Edit: Here's a video I recorded.

I see that you have checked the hard drive, but how about the file system?

Open a command prompt (use the 'run as Administrator' option) and type chkdsk /r.

When the computer crashes in games, is it the same games always? If so, that would suggest the file system problem.

Good to hear the Seatools check came out fine. Which test did you run?

 

[ivanlbc562]

I did the "chkdsk /r" and left it alone. I guess it completed while I was away because when I returned it was back at the home screen. Is there a log I can pull up somewhere? It still goes black/No Signal when I open the browser. It's gotten REALLY SLOW since yesterday...

Yes, there's only 4 games installed on that pc. (GTA IV, CS 1.6, CS:S, and L4D2) They all crash.

Seatools Long Generic Test. Thanks for the help

How's the video card?

 

[ivanlbc562]

How's the video card?

Not sure what you mean. It's about 6 months old that I bought from eBay for $45. How would I check if it's dying? Furmark or one of those kinda tests?

 

[Jaydip]

Can you down clock the video card and test again ? some of these factory oced models aren't stable at all.

 

[ivanlbc562]

Yeah I can do that. What do you suggest? Stock at 975mV / 1250 core / 1701 mem /

Stock at 975mV

Stock

 

[ivanlbc562]

Stock

Is that not stock on a EVGA GTX 470 SC? I googled it and read that was the stock clocks.

 

[denis280]

Reading all again. so far you did the chkdsk/r.check the disk.Now do you have anything overclock.is the Mobo set to default.and last did you try a clear CMOS.won't hurt.

Nope, everything should be stock. Haven't tried clearing the CMOS.

 

[denis280]

The fact.is the screen going black is usually gpu.the mouse going nuts could be virus.but since this happen after power surge.I would clear CMOS to refresh.

 

[ivanlbc562]

I cleared the CMOS , but it's still doing it. Should I just replace the 470?

Edit: Something weird just popped on my screen. It happened so fast and I couldn't read it, but it looked like it said "KOOM" with big overlapping letters in blue.

Gee, that sounds like a virus to me.

 

[John Connor]

Go into safe mode run Rkill and then Malwarebytes. I would boot a Bitdefender anti-virus CD and scan the drive.

[ivanlbc562]

Oh, well that sucks. That pc doesn't have a cd drive, can i run it from a flash drive?

 

[Ketchup]

Very rarely do I need to boot off a CD to remove a virus/malware. Running programs within Windows should do fine. I would start with Malwarebytes. Superantispyware has also done well for me.

Read here on how to put Bitdefender on USB. http://www.bitdefender.com/support/how-to-create-a-bitdefender-rescue-cd-627.html

Also, Koom (if you read that one right) is a keylogger: http://www.softpedia.com/get/Security/Keylogger-Monitoring/Koom.shtml

Oh damn. Will rkill+bitdefender+malwarebytes remove that or will I have to format?

 

[AnitaPeterson]

The nuclear option is preferable, if you have the time to spare.

 

[ivanlbc562]

I have the time, but that pc was never backed up since I bought it.

 

[ivanlbc562]

So, I booted Bitdefender from the USB and was doing a scan for about an hour. Now I have a black screen;no mouse. It's been like that for 30 minutes now. What should I do?

 

[John Connor]

Do you still see a black screen after you restart the computer without Bitdefender?

 

[ivanlbc562]

Nah, I just held the power button. I scanned and deleted 2 files while scanning "Sys Files." it's weird because it wouldn't let me do a "full scan" anymore. I'll update once I finish scanning the main drive... Hopefully it fixes it.
